Задвижка с пневмоуправлением

Pneumatically Actuated Gate Valves assemblies consist of three key components: an actuator, a carriage/gate and a valve body. The gate valves that have two series: HV series and UHV series. HV series valves are rotary action, linear travel gate valves. The gate carriage moves in the valve body on a set of wheels, moved back and forth by a manual or pneumatically-actuated valve stem.

We offers a wide variety of Pneumatically Actuated valve types in a comprehensive range of sizes.
Our vacuum gate valves are divided into pneumatical, with bellows and without bellows. And the vacuum gate valve sare available with KF, ISO, ANSI, JIS, and CF flange.

We designs all series gate valves suited for vacuum applications with venting processes, high vacuum applications in pumping systems, semiconductor technology, research systems, etc.
