Details Explanation
This series of valves is driven by both pneumatic and electric methods, with a reasonable structural design. It has the advantages of smooth operation, low impact vibration, reliable use, good sealing performance, and long service life. It is one of the preferred valves for automation of large vacuum equipment. A valve is driven by a pneumatic or electric actuator to push a push rod, which is connected to a hinge mechanism through the push rod to drive the hinge to move, thereby achieving the opening and closing actions of the valve.
Adopting a hinge mechanism to enlarge the valve stroke and increase the force arm; Four wheel support motion mechanism, smooth movement, low motion noise; Fork structure reduces valve friction loss, ensures smooth opening and closing of the valve, and increases sealing; The sealing ring is made of fluororubber, which provides reliable sealing and low air release rate; The valve is welded internally with stainless steel sections, resulting in a low leakage rate.
