Air Actuated Shut Off Globe Valve Product introduction
Air actuated shut off globe valve manufacturer, factory and supplier. Air actuated shut off globe valve is a kind of shut off valve with welded end or flanged end, top handwheel is optional, Air actuated shut off globe valve is a valve driven by compressed air, which is mainly composed of pneumatic actuators, handwheel actuators, pneumatic control components, signal switches, welded end globe valves, etc., and the compressed air enters the pneumatic actuator to drive the cylinder to connect the valve stem spool valve disc to do lifting movement. Pneumatic on off globe valve uses compressed air to drive the movement of multiple groups of combined pneumatic piston in the actuator, transmits force to the beam and the characteristics of the inner curve track, drives the empty core spindle to rotate, the compressed air disc is transmitted to each cylinder, changes the inlet and outlet position to change the direction of spindle rotation, according to the requirements of the rotating torque required by the load stop valve, the number of cylinder combinations can be adjusted to drive the load stop valve. Air actuated shut off globe valve Pneumatic actuators are generally pneumatic spring piston type and pneumatic cylinder piston type, the former is a single-acting spring return type, the latter is a double-acting gas closed gas open type.
Air actuated shut off globe valve adopts the self-sealing working principle, the medium enters the valve chamber from the top of the valve disc, under the action of the medium pressure, the closing force of the globe valve is small, and the opening force is large, and the diameter of the valve stem can correspondingly reduce the impact force of the fluid. At the same time, under the action of medium pressure, this form of valve is also more tight.
