Standard pneumatic actuator is committed to improving energy saving and safety, with fast response, small size, long life and so on. Has a number of patented technologies: carbon graphite filled PTFE (Teflon) piston guide point patent, carbon graphite filled PTFE (Teflon) piston seal patent, self-lubricating drive pin patent. Fork type special structure, increase the output torque, to meet the ball valve, butterfly valve opening and closing requirements for greater torque. The moving parts are made of reinforced alloy steel, with ultra-long durability (1,000,000 cycles of operation test).
