EVR 40 NC/NO Hot gas defrostingWith hot gas defrosting it is not normally possible to select a valve from condensing temperature t c and evaporating temperature t e .This is because the pressure in the evaporator as a rule quickly rises to a value near that of the condensing pressure. It remains at this value until the defrosting is finished.In most cases therefore, the valve will be selected from condensing temperature t c and pressure drop ?p across the valve, as shown in the example for heat recovery.Heat recovery The following is given: y Refrigerant = R22/R407Cy Evaporating temperature t e = -30 °C y Condensingtemperature t c = 40 °Cy Hot gas temperature ahead of valve t h = 85 °Cy Heat recovery condenser yield Q h = 8 kWThe capacity table for R22/R407C with t c = 40 °C gives the capacity for an EVR 10 as 8.9 kW, when pressure drop ?p is 0.2 bar.The required capacity is calculated as :Q table = f evaporator x f hot_temperature x Q hThe correction factor for t e = -30 °C is given in the table as 0.95.The correction for hot gas temperature t h = 85 °C has been calculated as 4% which corresponds to a factor of 1.04.Q h must be corrected with factors found: With ?p = 0.2 baris Q h = 8.71 x 0.95 x 1.04 = 8.6 kW.With ?p = 0.1 bar, Q h becomes only 6.19 x 0.95 x 1.04 = 6.1 kW.An EVR 6 would also be able to give the required capacity, but with ?p at approx. 1 bar. The EVR 6 is therefore too small.The EVR 15 is so large that it is doubtful whether the necessary ?p of approx. 0.1 bar could be obtained.An EVR 15 would therefore be too large.Result: An EVR 10 is the correct valve for the given conditions.Capacity Suction (continued)Data sheetSolenoid valve, types EVR 2 ? EVR 40 NC/NOR22/R407CAn increase in hot gas temperature t h of 10 K, based on t h = t c +25 °C, reduces valve capacity approx. 2% and vice versa.A change in evaporating temperature t e changes valve capacity; see correction factor table below.Correction factorsWhen sizing valves, the table value mustbe multiplied by a correction factor depending on evaporating temperature t e .Correction factors for evaporating temperature teCapacity Hot gas。

Direct operationEVRA 3 is direct operated. The valve opens direct for full flow when the armature (16) moves up into the magnetic field of the coil. This means that the valve operates with a min. differential pressure of 0 bar.The teflon valve plate (18) is fitted direct on the armature (16).Inlet pressure acts from above on the armature and the valve plate. Thus, inlet pressure, spring force and the weight of the armature act to close the valve when the coil is currentless.2. Servo operationEVRA 10 ® 20 are servo operated with a "floating" diaphragm (80). The pilot orifice (29) of stainless steel is placed in the centre of the diaphragm. The teflon pilot valve plate (18) is fitted direct to the armature (16).When the coil is currentless, the main orifice and pilot orifice are closed. The pilot orifice and main orifice are held closed by the weight of the armature, the armature spring force and the differential pressure between inlet and outlet sides.When current is applied to the coil the armature is drawn up into the magnetic field and opens the pilot orifice. This relieves the pressure above the diaphragm, i.e. the space above the diaphragm becomes connected to the outlet side of the valve.The differential pressure between inlet and outlet sides then presses the diaphragm away from the main orifice and opens it for full flow. Thereforea certain minimum differential pressure is necessary to open the valve and keep it open. For EVRA 10 ® 20 valves this differential pressure is 0.05 bar.When current is switched off, the pilot orifice closes. Via the equalization holes (73) in the diaphragm, the pressure above the diaphragm then rises to the same value as the inlet pressure and the diaphragm closes the main orifice.EVRA 25, 32 and 40 are servo operated piston valves. The valves are closed with currentless coil.The servo piston (80) with main valve plate (84) closes against the valve seat (83) by means of the differential pressure between inlet and outlet side of the valve, the force of the compression spring (76) and possibly the piston weight. When current to the coil is switched on, the pilot orifice (29) opens. This relieves the pressure on the piston spring side of the valve. The differen-tial pressure will then open the valve.The minimum differential pressure needed for full opening of the valves is 0.07 bar.4.Coil 16.Armature18.Valve plate / Pilot valve plate 20.Earth terminal24.Connection for flexible steelhose28.Gasket29.Pilot orifice30.O-ring31.Piston ring36.DIN plug40.Terminal box43.Valve cover44.O-ring45.Valve cover gasket48.Flange gasket49.Valve body51.Cover / Threaded plug52.Lock button and top nut53.Manual operation spindle 59.Strainer73.Equalization hole74.Main channel75.Pilot channelpression spring80.Diaphragm/Servo piston82.Support washer83.Valve seat84.Main valve plate EVRA 3EVRA 10, 15 and 20 EVRA 25EVRA 32 and 40Dimensions and weightsEVRA 3 ® 20Coil with terminal boxWeight of coil10 W: approx. 0.3 kg12 and 20 W: approx. 0.5 kg Weight of flange setFor EVRA 3, 10 and 15: 0.6 kgFor EVRA 20: 0.9 kgEVRA 10 ® 20Coil with terminal boxEVRA 10Coil with terminal boxEVRA 3Coil with cableEVRA 3 ® 20Coil with DIN plugsmmmm mm mm mm mm mmmmmm mm kg 1) With coil, without flangesEVRA 38419124658068 1.2EVRA 102210081130688068 1.7EVRA 1510081130688068 1.8EVRA 20110771558596682.77585B 1max.Weight 1)L 5 max.12 W 20 W 10 W B H 1H 2H 3H 4L L 1TypeDimensions and weights (continued)Weight of coil10 W: approx. 0.3 kg12 and 20 W: approx. 0.5 kgWeight of flange set For EVRA 25: 0.9 kgEVRA 25Coil with terminal boxEVRA 32 and 40Coil with terminal boxEVRA 25Coil with terminal boxEVRA 25, 32 and 40Coil with DIN plugsEVRA 25, 32 and 40Coil with cable EVRA 32 and 40Coil with terminal boxmmmm mmmm mm mm mmmmmm mm kg EVRA 254614178162929568 3.0EVRA 32471155318075858068 4.0EVRA 40471155320080684.0B 1max.Weight 1)L 5 max.12 W 20 W 10 W B H 1H 2H 3H 4L L 1Type1) With coil, without flanges。

It remains at this value until the defrosting is finished.In most cases therefore, the valve will be selected from condensing temperature t c and pressure drop ∆p across the valve, as shown in the example for heat recovery.Heat recoveryThe following is given: y Refrigerant = R22/R407Cy Evaporating temperature t e = -30 °C y Condensing temperature t c = 40 °Cy Hot gas temperature ahead of valve t h = 85 °Cy Heat recovery condenser yield Q h = 8 kWThe capacity table for R22/R407C with t c = 40 °C gives the capacity for an EVR 10 as 8.9 kW, when pressure drop ∆p is 0.2 bar.The required capacity is calculated as :Q table = f evaporator x f hot_temperature x Q hThe correction factor for t e = -30 °C is given in the table as 0.95.The correction for hot gas temperature t h = 85 °C has been calculated as 4% which corresponds to a factor of 1.04.Q h must be corrected with factors found: With ∆p = 0.2 baris Q h = 8.71 x 0.95 x 1.04 = 8.6 kW.With ∆p = 0.1 bar, Q h becomes only 6.19 x 0.95 x 1.04 = 6.1 kW.An EVR 6 would also be able to give the required capacity, but with ∆p at approx. 1 bar. The EVR 6 is therefore too small.The EVR 15 is so large that it is doubtful whether the necessary ∆p of approx. 0.1 bar could be obtained.An EVR 15 would therefore be too large.Result: An EVR 10 is the correct valve for the given conditions.Capacity Suction (continued)R22/R407CAn increase in hot gas temperature t h of 10 K, based on t h = t c +25 °C, reduces valve capacity approx. 2% and vice versa.A change in evaporating temperature t e changes valve capacity;

Main valve plateEVR 32 and EVR 40 (NC)EVR 25 (NC)Design (continued)Note :The drawings are only representative.Function EVR solenoid valves are designedon two different principles:1. Direct operation2. Servo operation1. Direct operationEVR 2 – EVR 3 are direct operated. The valves open directly for full flow when the armature (16) moves up into the magnetic field of the coil. This means that the valves operate with a min differential pressure of 0 bar.The valve plate (18) is fitted directly on the armature (16).Inlet pressure acts from above on the armature and the valve plate. Thus, inlet pressure and spring force act to close the valve when the coil is currentless.2. Servo operationEVR 6 – EVR 22 are servo operated with a "floating" diaphragm (80). The pilot orifice (29) of stainless steel is placed in the centre of the diaphragm. The pilot valve plate (18) is fitted directly to the armature (16). When the coil is currentless, the main orifice and pilot orifice are closed. The pilot orifice and main orifice are held closed by the armature spring force and the differential pressure between inlet andoutlet sides.When current is applied to the coil the armature is drawn up into the magnetic field and opens the pilot orifice. This relieves the pressure above the diaphragm, i.e. the space above the diaphragm becomes connected to the outlet side of the valve. The differential pressure between inlet and outlet sides then presses the diaphragm away from the main orifice and opens it for full flow. Therefore a certain minimum differential pressure is necessary to open the valve and keep it open. For EVR 6 – EVR 22 valves this differential pressure is 0.05 bar.When current is switched off, the pilot orifice closes. Via the equalization holes (73) in the diaphragm, the pressure above the diaphragm then rises to the same value as the inlet pressure and the diaphragm closes the main orifice.EVR 25, EVR 32 and EVR 40 are servo operated piston valves. The valves are closed with currentless coil. The servo piston (80) with main valve plate (84) closes against the valve seat (83) by means of the differential pressure between inlet and outlet side of the valve and the force of the compression spring (76). When current to the coil is switched on, the pilot orifice (29) opens. This relieves the pressure on the piston spring side of the valve. The differential pressure will then open the valve. The minimum differential pressure needed for full opening of the valves is 0.2 bar. EVR (NO) has the opposite function to EVR (NC), i.e. it is open with de-energised coil.EVR (NO) is available with servo operation only.Material specifications EVR 2 – EVR 25Note:The drawings are only representative.Material specifications (continued)EVR 32 – EVR 40Note :The drawing is only representative.With DIN plugs coilWith cable connection coilNet weight of coil 10 W: approx. 0.3 kg12 and 20 W: approx. 0.5 kgWith terminal box coilDimensions [mm] and weights [kg]EVR 2 – EVR 6 NC/NO, solder connection For 3D models, visit /products/categories/Note :The drawings are only representative.。
