HYK-VAA ZSC SeriesPneumatic diaphragm actuatorGENERALThis Series provides high performance, high power diaphragm actuators of multi-spring type that are compact and light. Receiving pneumatic or electric signals, the unit balances the force created when diaphragm is airpressured through positioner and the force of compressed spring, so that the output shaft is controlled and placed at a set position. Control of position by pneumatic signals(20100KPa) directly applied on diaphragm is also possible.Combination with VAA positioner provides high accuracy position control.STANDARD SPECIFICATIONSSeries ZSCType Multi-spring typeSize210、230、340、450、560FunctionDirect acting (DA) ：Air to output shaft down.Reverse acting (RA) ：Air to output shaft up.Output forceSee Table 1.StrokeSee Table 2.Air supply 140 KPa G 、300 KPa G 、350 KPa GSpring range20100 KPa G、80200 KPa G120300 KPa G 210、230 Size：210、230 onlyPerformanceHysteresis ：Less than 0.8% of Full stroke with positioner.Less than 1.0% of Full stroke with positioner for Spring range 120300KPa G.Less than 5% of Full stroke without positioner.Linearity ：Less than 1.5% of Full stroke with positioner.Less than 2% of Full stroke with positioner for Spring range 120300KPa G.Less than 4% of Full stroke without positioner.* The above hyteresis and linearity vary depending on the gland packing material of11the control valves.Ambient temperatureStandard type1070High temperature service (option) 0100Low temperature service (option)4040MaterialsDiaphragm case SPHEDiaphragm EPDMDrive shaft SUS303Yoke FCPaintingOrange ( Epoxy resin group )AccessoriesEP Positioner, PP Positioner, Air-set, Booster relay, Air-valve, Limit switch,Solenoid valve, Lock-valve, Speed controller, Position transmitter, etc.OptionManual hand-wheel, Yoke material, Special air piping, Special air fitting, Low temperature service, High temperature service, Tropical area proof, Salty environment proof, Cold area proof, Non-standard painting, etc.Table 1.
