Spring return fail close pneumatic actuated ball valve introduction:
Spring return fail close pneumatic actuated ball valve is mainly composed of floating ball valve, pneumatic actuator and related accessories. Spring return fail close pneumatic actuated ball valve body adopts the silicon dissolves the tumble precision casting. Spring return fail close pneumatic actuated ball valve has the high platform design. Through the compressed air as the power source, we may control the ball valve to open and close. Spring return fail close pneumatic actuated 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.
