Product Description
Construction of double acting pneumatic actuator 1, Actuator Body:  the extruded aluminum alloy ASTM6005 body can be treated with hard anodized, powder  polyester  painted ( different colors is available such as blue, orange, yellow etc.),PTFE or Nickel plated according to different requirements.2, The twin rack pistons are made form Die-casting aluminum treated with Hard anodized or made form Cast steel  with galvanization. Symmetric mounting position, long cycle life and fast operation, reversing rotation by simply inverting the pistons. 3, Preloaded coating springs are made form the high quality material for resistant to corrosion and longer service life, which can be denounced safely and conveniently to satisfy different requirements of torque by changing quantity of springs4, NBR rubber O-rings provide trouble-free operation at standard temperature ranges.For high and low temperature applications viton or Silicone.Double acting pneumatic actuator's operating modeThere are two operating modes1, when ball valve closed, Air to Port A forces the pistons outwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port B. When ball valve opened, Air to Port B forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port A 2, when ball valve closed, Air to Port A forces the pistons outwards, causing the pinion to turn clockwise while the air is being exhausted from Port B. Air to Port B forces the pistons inwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port A.Double acting pneumatic actuator's operating condition1, medium : Dry or lubricated air, or the non-corrosive gas2, air supply pressure: the minimum supply pressure is 2.5 Barthe maximum supply pressure is 8 Bar3, travel adjustment : have adjustment range of ±5° for the rotation at 0°and 90°Main technical data for ball valves1, BALL VALVE MATERIALbody material : WCB, LCB, A105, CF8,CF8M,F304,F316 ball material : A105, LF2,304,316,316Lstem material : 420, LF2,F304,F316Seat material : PTEF,PEEK,PPL2, BALL VALVE STRUCTUREFloating ball and trunnion mounted ball with 2-piece or 3-piece body3, CONNECTION ENDDouble flanged end, screwed end, wafer end, butt welded end4, VALVE STANDARDDesign : API 608, API6D,ASME B16.34, DIN3357/1 Length of face to face : ASME B 16.10, DIN 3202 F1 or F7Flange end : ASME B16.5, EN1092-1Thread end: ASME B16.11Test : API 598, BS EN 12266, ISO 52085, VALVE SIZE and PRESSURE RANGENPS : 1/2'' - 8''for floating ball valve and wafer ball valve1/2''-4''for thread end ball valve2''-20''for trunnion mounted ball valvePressure : 150 LB - 1500 LB, PN10-PN646, ISO5211 DIRECT MOINTING PADFor ball valve connection size information, pls check our ball valve page of this website !
