Brief IntroductionSplit body (2-piece) valve allows easy replacement of gasket, seal, and seats without special tools. Series 90 ball valves use “floating ball” design. Induced by the line pressure the ball is free to move horizontally inside the valve body. The valve is capable of tight shutoff with flow in either direction or dead-end, regardless of the position of the valve in the line. The downstream seat, opposite the pressurized side of a closed valve, carries the load exerted by the line pressure on the ball, while the upstream seat is subject to little load or wear. For this reason, it is sometimes possible to increase seat life by turning the valve end-for-end in the pipeline.1. USE:1.1 Life of valve can be maximized if the valve is used within the rated range, in accordance with pressure, temperature,and corrosion data.2. MANUAL OPERATION:2.1 To open or close the valve, turn the handle ¼ turn (90 degrees).A. Valve in Open Position – the handle is in parallel (in-line) with the valve or pipeline.B. Valve in Closed Position – the handle is perpendicular (crossed) with the valve or pipeline.3. AUTOMATED OPERATION:3.1 Valves with actuators should be checked for valve stem alignment. Angular or linear misalignment will result in highoperational torque and unnecessary wear on the stem seal.4. GENERAL INFORMATION FOR ON-SITE INSTALLATION:4.1 The valve may be fitted in any position on the pipeline.4.2 To prevent damage to the seats and ball surface, the pipeline must be flushed, free of dirt, burrs, and weldingresidues before installing the valve.5. DISASSEMBLING & CLEANING THE VALVE:5.1 If the valve has been used in hazardous media, it must be decontaminated before disassembly.5.2 As shipped from the factory, valves contain silicon-free lubricant. If Lubricant is unacceptable for your particularapplication, you may disassemble the valve and wash the parts in solvent.6. REPLACING THE THRUST WASHER AND PACKING6.1 Before replacing the thrust washer and the packing, the pipeline must be de-pressurized.Note: Stem seal leakage may be corrected without replacing the seal and/or packing. Tighten the packing nut toflatten the belleville washers. If leakage continues or valve’s operating torque becomes excessive, the seals are worn and must be replaced.A. Remove flange bolts and nuts and lift the valve from the line. Care should be taken to avoid scratching ordamaging serrated gasket. The valves are heavy, and they should be adequately supported before removing it from the line.B. Loosen the stem nut and remove handle and stop plate. Next, remove lock saddle, packing nuts, bellevillewashers and gland.C. Remove body bolt nuts, using proper wrench. Lift off body end. One seat should come out with the body end.D. Remove body seal.E. To take out the ball, rotate stem so ball is in fully closed position. Lift ball from the body, using a strap and liftdevice, if necessary. Extreme caution should be taken to avoid damage to the ball. F. Take out the other seat.G. Stem must be removed from inside the body. A tap to the top of the stem should loosen it. The thrust washershould come out with the stem. Then, remove the stem packing.7. VISUAL INSPECTION:7.1 Clean and inspect metal parts. It is not necessary to replace neither ball nor stem unless the surface has signs ofabrasion or corrosion. We strongly recommend replacement of all soft parts whenever the valve is disassembled for reconditioning. We provide replacement kits that contain all the replaceable parts.Note: The valve may be assembled and operated dry with any lubricant. However, a light lubrication will aid inassembly and reduce initial operating torque. Lubricant used must be acceptable with the intended line fluid.8. ASSEMBLYInstall one seat in the body cavity with the spherical curvature facing the ball.8.1 Install the thrust washer on stem and slide the stem up through the body. Install packing, gland, belleville washers,locking saddle. Screw the packing nut into the stem. Lock the saddle in place.8.3 Install stop plate, handle and washer. Screw the stem nut into the stem until the handle is secure.8.4 Turn handle to the closed position. Line up the ball slot with the stem end and slide the ball into position. Turn thehandle to the open position to hold the ball in place. 8.5 Install the remaining seat into body side.8.6 Put body seal gasket into body and line up end flange. Because the body flange bolt pattern is different from the lineflange bolt pattern, it is possible to assemble the valve such that the line flanges bolt pattern don’t line up. Be certain to align end flanges bolt holes to straddle valve center lines. Be careful not to damage body seal when putting cap end into body.8.8 Install cap end nuts and tighten in the “star” pattern to the proper torque. Extreme care must be exercised duringadjustment of cap end nuts to make sure that complete engagement of the studs with body flange is maintained. There should be at least one stud thread exposed on each side.8.9 Cycle the valve slowly, with a gentle back and forth motion, to build gradually to the full quarter turn. By cyclingslowly, the seat lips will assume a permanent seal shape against the ball. A fast turning motion, at this point, may cut the seats before they have a chance to form the proper seal.8.10 Test valve, if possible, prior to placing valve back into line position. If not properly secured, the valve can separatefrom the pressure source, resulting in possible injury. Always join the valve to companion flanges of same pressure rating as valve and secure with a full set of flange bolts.TEST AS FOLLOWS:A. Secure valve to a test fixture by means of a mating flange with full bolting and a suitable gasket. Orient valve soseat to be tested is facing up.B. Introduce 50 to 100 psig air. Partially cycle the valve, under pressure, then slowly close to make sure the cavity ispressurized (use hearing protection). Pour water into the upper port to cover the ball and visually check for bubbles. If bubbles appear, pour the water out, cycle the valve several times and recheck. To check for leakage in the other port, reverse the valve and introduce air pressure to the port just checked.C. Check stem seal at this time by coating the stem top area with a water/soap solution. If leakage occurs, tighten stemseal just until leakage stops.Valve SizeBreak Away Torque(In-lbs.)Torque of Body Bolts(In-lbs.)Torque of Stem Nut(In-lbs.)½” 92 95 ~ 130 87 ¾” 115 122 ~ 156 87 1” 150 365 ~ 399 130 1-1/2” 320 365 ~ 399 208 2” 415 365 ~ 399 208 2-1/2” 675 365 ~ 399 208 3” 1000 477 ~ 521 304 4”1800477 ~ 521304A-T Controls product, when properly selected, is designed to perform its intended function safely during its useful life.

In order to avoid danger, Valve allows theuse temperature between-20℃to 200℃, and doesn't allow more than this temperaturerange.c.流动性热的扩充: Liquidity thermal expansion当球阀在封闭的条件下工作，阀体内的封闭腔体可能封有流体。
若流体不能被及时释放出来，将会升温膨胀，导致压力边缘失效。
而我们的产品具有球垫压力自动调节功能，能够预防压力增强。
建议用户通过管道系统设计、安装或操作程序等方法来进行预防，以避免阀体内压力超过额定压力值。
When ball valve working in the closed conditions, the valve body of closed cavity couldseal a fluid. If the fluid can not be released in time, it will be heating expansion, leading to the failure of pressure edges. However, our products have the cushion pressureautoregulation, preventing pressure increase. To avoid the valve body pressure exceed the rated value, we recommend that users through the piping system design, installation oroperation procedure and methods for prevention.d.静电影响:Electrostatic effect南京苯邦阀门公司球阀具有抗静电能力，当使用环境连续用电需要预防静电时，阀门应有接地，以使静电能够即时得以释放。
Ball valves have the antistatic ability. When the using environment continuous electricity needs to prevent static electricity, the valve should be grounded, so that static electricity can be released immediately.e.意外火灾预防:Accidental fire prevention通常，球阀的使用应遵守压力温度要求。
如果发生意外火灾时造成的危险较大，建议您选择我们的防火型产品。

If causing greater risk in the event of accidental fires, it is recommended that you choose our fire protection products. The product has passed the API - 607certification. For details, please contact with the valve sales or contact with us directly.f.液体流速:Liquid velocity当球阀必须经常在高速流体条件下频繁开关时，销售商或制造商应适当建议最小化密封垫变形的可能性，尤其是在高温线上进行高温密封的球阀，并进行检查。
When the ball valve must always frequently switch in high speed fluid condition, vendors or manufacturers should suggest to minimize the possibility of Gasket deformationappropriately, especially the ball valves in the high- temperature line for high-temperature sealing, and check.g.节流装置：Throttling device当用阀门做为节流装置时，流体和钢球的前边缘能损坏密封垫的回弹力，导致泄露。
因此建议球阀一般不要用做节流。
用做节流时产生的高流体流速及悬浮固体颗粒将进一步缩短密封垫的使用寿命。
When the valves used as the throttle device, fluid and the front edge of the ball candamage the resiliency of the gasket, causing leakage. So, we suggest that ball valvegenerally don't used as throttle. High fluid velocity used for throttling and suspended solids will further shorten the service life of the seal.h.当打开阀门困难时，（阀体内正承受压力时）不要拧开螺帽检查。
