2-position, 6-way, soft shift, solenoid-operated directional spool valve Capacity:5 gpm (20 L/min.)Functional Group:Products : Cartridges : Directional : 6 Way : 2 Position, 6 Way Spool, Soft Shift, Solenoid OperatedModel: DNDYSProduct DescriptionThis solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve with a soft shift feature. The soft shift feature greatly reduces system shock due to valve actuation. The typical use for this valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit and when energized connects P and T to the second circuit.Technical FeaturesThe soft shift cartridge is interchangeable with the standard cartridge, however, the performance limits are lower. This valve is direct actuated and requires no minimum hydraulic pressure for operation.The soft shift feature can greatly reduce shock due to valve actuation but should not be counted upon in applications where timing is critical. If you need accurate ramping or timing control, consider Sun's electro-proportional valves. This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.The soft shift feature results in significant increase in response time over Sun's standard solenoid. Response time is dependant on flow, pressure, coil voltage, oil viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms. The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.For consistent soft shift performance, port 1 should be at a positive pressure. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.This valve includes a push-type manual override control. Other manual control options such as T or D, cannot be ordered with the soft shift control but can be installed easily in the field. See Twist/Lock Manual Override link above for details. Please note: Manual override functionality is not compatible with weatherized coils. Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service. Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.Special NotesPlease verify cartridge clearance when choosing a Sun manifold. Different valve controls and coils require different clearances.DownloadDNDY-SXN-*** $184.40Recommended List PriceSpool ConfigurationSeal MaterialCoilStandard OptionsX-+0.00Standard OptionsN Buna-N +0.00VViton+6.00*** See Coil Options Below Standard Coil Options (View All )DIN 43650 3 pin (Hirschman) SAE J858AAMP Junior TimerTwin LeadMetri-PackDeutsch DT04-2P*** no coil528 SAE J858A, 28 VDC, +25.30 814 Metri-Pack, 14 VDC, +27.70211DIN 43650 3 pin(Hirschman), 115 VAC, +36.40 536SAE J858A, 36 VDC, +22.50 814N Metri-Pack, 14 VDC, notransient voltagesuppression (TVS) diodes+27.20212DIN 43650 3 pin(Hirschman), 12 VDC,+20.40 612AMP Junior Timer, 12 VDC, +19.90 824Metri-Pack, 24 VDC, +24.90212N DIN 43650 3 pin(Hirschman), 12 VDC, notransient voltagesuppression (TVS) diodes +19.90 612N AMP Junior Timer, 12 VDC,no transient voltagesuppression (TVS) diodes+19.40 828Metri-Pack, 28 VDC, +27.70214DIN 43650 3 pin(Hirschman), 14 VDC,+23.20 614AMP Junior Timer, 14 VDC, +22.60 836Metri-Pack, 36 VDC, +27.70214N DIN 43650 3 pin(Hirschman), 14 VDC, notransient voltagesuppression (TVS) diodes+22.70 624AMP Junior Timer, 24 VDC, +19.90 848Metri-Pack, 48 VDC, +27.70223DIN 43650 3 pin(Hirschman), 230 VAC, +36.40 624N AMP Junior Timer, 24 VDC,no transient voltagesuppression (TVS) diodes+19.40 912Deutsch DT04-2P, 12 VDC, +26.20224DIN 43650 3 pin(Hirschman), 24 VDC, +20.40 628AMP Junior Timer, 28 VDC, +22.60 912N Deutsch DT04-2P, 12 VDC,no transient voltagesuppression (TVS) diodes+25.70224N DIN 43650 3 pin(Hirschman), 24 VDC, notransient voltagesuppression (TVS) diodes+19.90 636AMP Junior Timer, 36 VDC, +22.60 914Deutsch DT04-2P, 14 VDC, +29.10228DIN 43650 3 pin(Hirschman), 28 VDC, +23.20 712Twin Lead, 12 VDC, +22.50 914N Deutsch DT04-2P, 14 VDC,no transient voltagesuppression (TVS) diodes+28.60236DIN 43650 3 pin(Hirschman), 36 VDC, +23.20 712N Twin Lead, 12 VDC, notransient voltagesuppression (TVS) diodes+22.00 924Deutsch DT04-2P, 24 VDC, +26.20248DIN 43650 3 pin(Hirschman), 48 VDC, +23.20 724Twin Lead, 24 VDC, +22.50 924N Deutsch DT04-2P, 24 VDC,no transient voltagesuppression (TVS) diodes+25.70297DIN 43650 3 pin(Hirschman), 24 VAC, +48.80 724N Twin Lead, 24 VDC, notransient voltagesuppression (TVS) diodes+22.00 928Deutsch DT04-2P, 28 VDC, +29.10298DIN 43650 3 pin(Hirschman), 220 VDC,+48.80 728Twin Lead, 28 VDC, +25.30 936Deutsch DT04-2P, 36 VDC, +29.10299DIN 43650 3 pin(Hirschman), 127 VDC,+48.80 736Twin Lead, 36 VDC, +25.30 948Deutsch DT04-2P, 48 VDC, +29.10514SAE J858A, 14 VDC, +25.30 812Metri-Pack, 12 VDC, +24.90 HN24AA Hazardous environmentduty, 1/2 inch MPTmechanical conduit, 24VDC, 10 feet twin lead,ATEX Certification Ex mb IICT3 Gb.+852.00524SAE J858A, 24 VDC, +22.50 812N Metri-Pack, 12 VDC, notransient voltagesuppression (TVS) diodes +24.40 HN24AB Hazardous environmentduty, 1/2 inch MPTmechanical conduit, 24VDC, 10 feet twin lead, CSACertification+852.00Embedded Coil Options (Click Here)2E12V DIN 43650 3 pin(Hirschman), programmablevia IR link coil/power saver,12 VDC, 0-10V +172.90 4E12V Deutsch DT04-6P,programmable via IR linkcoil/power saver, 12 VDC, 0-10V+161.10 4E24V Deutsch DT04-6P,programmable via IR linkcoil/power saver, 24 VDC, 0-10V+161.102E24V DIN 43650 3 pin(Hirschman), programmablevia IR link coil/power saver,24 VDC, 0-10V+172.90 Additional Options (Click Here)Additional Coils512SAE J858A, 12 VDC, +22.50 71219Twin Lead, to DelphiWeather-Pack Connector, 9inch lead length, 12 VDC, +33.40 72419Twin Lead, to DelphiWeather-Pack Connector, 9inch lead length 24 VDC,+33.40548SAE J858A, 48 VDC, +22.50 71299Twin Lead, to Deutschconnector, 9 inch leadlength, +34.70 72499Twin Lead, to Deutschconnector, 9 inch leadlength,+34.70648AMP Junior Timer, 48 VDC, +22.60 714Twin Lead, 14 VDC, +25.30 748Twin Lead, 48 VDC, +25.30 Stainless options not available for this modelRelated ModelsDNDYCopyright © 2002-2013 Sun Hydraulics Corporation.

2-way, solenoid-operated directional spool valve with position switchCapacity:12 gpm (45 L/min.)Functional Group:Products : Cartridges : Solenoid Operated : 2-Way : Spool with Position Indicating SwitchModel: DLDAZProduct DescriptionThis solenoid-operated 2-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The valve is available in either a normally open or normally closed configuration.The position switch provides confirmation that the valve is in the spring biased position.Technical FeaturesA coil must be ordered with this cartridge. This cartridge is supplied as a sealed, factory set unit and is not field serviceable. If the assembly requires changes or service it needs to be returned to the factory.Any tampering will violate the product warranty. This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.Position switch is CE approved.A wide variety of coil termination and voltage options are available. When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.The solenoid's unique magnetic design results in a high efficiencysolenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.Incorporates the Sun floating style construction to minimize thepossibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.This valve is direct actuated and requires no minimum hydraulic pressure for operation.C-Spool DownloadH-Spool DownloadDLDA-ZCN-224 $575.00Recommended List PriceSpool ConfigurationSeal MaterialCoilStandard Options C Normally Closed +0.00HNormally Open+0.00Standard OptionsN Buna-N +0.00VViton+3.50*** See Coil Options Below Standard Coil Options (View All )DIN 43650 3 pin (Hirschman)AMP Junior TimerTwin LeadMetri-PackDeutsch DT04-2P211DIN 43650 3 pin(Hirschman) 115 VAC +36.40 612 AMP Junior Timer 12 VDC +19.90 812NMetri-Pack 12 VDC no transient voltagesuppression (TVS) diodes +24.40212 DIN 43650 3 pin+20.40 612NAMP Junior Timer 12 VDC no+19.40 824Metri-Pack 24 VDC+24.90(Hirschman) 12 VDC transient voltagesuppression (TVS) diodes212N DIN 43650 3 pin(Hirschman) 12 VDC notransient voltagesuppression (TVS) diodes+19.90 624AMP Junior Timer 24 VDC +19.90 912Deutsch DT04-2P 12 VDC +26.20214N DIN 43650 3 pin(Hirschman) 14 VDC notransient voltagesuppression (TVS) diodes +22.70 624N AMP Junior Timer 24 VDC notransient voltagesuppression (TVS) diodes+19.40 912N Deutsch DT04-2P 12 VDC notransient voltagesuppression (TVS) diodes+25.70223DIN 43650 3 pin(Hirschman) 230 VAC +36.40 724N Twin Lead 24 VDC notransient voltagesuppression (TVS) diodes+22.00 924Deutsch DT04-2P 24 VDC +26.20224DIN 43650 3 pin(Hirschman) 24 VDC +20.40 812Metri-Pack 12 VDC +24.90 924N Deutsch DT04-2P 24 VDC notransient voltagesuppression (TVS) diodes+25.70224N DIN 43650 3 pin(Hirschman) 24 VDC notransient voltagesuppression (TVS) diodes+19.90Stainless options not available for this modelRelated ModelsDLDA DLDASCopyright © 2002-2013 Sun Hydraulics Corporation.

3-way, solenoid-operated directional spool valve - pilot capacityCapacity:.25 gpm (1 L/min.)Functional Group:Products : Cartridges : Directional : 3 Way : Solenoid Operated SpoolModel: DBAAProduct DescriptionThis solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool pilot valve used to pilot other full-flow valves. The valve is normally open between port 1 and port 2 or port 1 and port 3 and all flow paths are bidirectional.Technical FeaturesThe solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.This valve is direct actuated and requires no minimum hydraulic pressure for operation.A wide variety of coil termination and voltage options are available. Highly efficient tube design requires only 12 Watts to shift the valve. Coils are interchangeable with other Sun Series P pilot solenoid products and can be mounted on the tube in either direction.Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @ 350 bar).Incorporates the Sun floating style construction to minimize thepossibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.C-Spool Download H-Spool DownloadDBAA-MCN-***$112.20Recommended List PriceControl Spool Configuration Seal Material CoilStandard OptionsC Concealed ManualOverride+0.00M Manual Override +0.00Standard OptionsC Normally Open 1 to 3,Closed 1 to 2+0.00H Normally Open 1 to 2,Closed 1 to 3+0.00Standard OptionsN Buna-N +0.00V Viton +5.00***See Coil Options Below Standard Coil Options (View All)DIN 43650 3 pin(Hirschman)SAE J858A Twin Lead*** no coil 236DIN 43650 3 pin(Hirschman) 36 VDC+34.90 506SAE J858A 6 VDC +31.40206DIN 43650 3 pin(Hirschman) 6 VDC+34.90 248DIN 43650 3 pin(Hirschman) 48 VDC+34.90 512SAE J858A 12 VDC +31.40211DIN 43650 3 pin(Hirschman) 115 VAC+45.00 311NFPA 115 VAC +80.00 524SAE J858A 24 VDC +31.40212DIN 43650 3 pin(Hirschman) 12 VDC+34.90 323NFPA 230 VAC +85.10 712Twin Lead 12 VDC +31.40223DIN 43650 3 pin(Hirschman) 230 VAC+45.00 324NFPA 24 VDC +68.30 724Twin Lead 24 VDC +31.40224DIN 43650 3 pin+34.90(Hirschman) 24 VDCAdditional Options (Click Here)Additional Coils706Twin Lead 6 VDC +31.40Stainless options not available for this modelCopyright © 2002-2012 Sun Hydraulics Corporation.
