Single acting spring return fail open Pneumatic ball valve introduction:
Single acting spring return fail open Pneumatic ball valve is mainly composed of floating ball valve or trunnion ball valve, pneumatic actuator and related accessories. Single acting spring return fail open Pneumatic ball valve body adopts the silicon dissolves the tumble precision casting. Single acting spring return fail open Pneumatic ball valve has the high platform or yoke connection design. Through the compressed air as the power source, we may control the ball valve to open and close. Single acting spring return fail open Pneumatic ball valve overall structure is compact, switch quickly, which is equipped with electrical valve positioner, receive 4-20 mA control signal of industrial automation control system, to complete the adjustment of pipeline medium flow, pressure, temperature and other technical parameters, to achieve automatic control.
