Description

The VZXA angle seat valves are externally operated valves which are controlled by a direct intake of compressed air and are used to shut off gassing or liquid media in piping systems. In the process, a spindle with a soft sealing valve disc is raised and lowered with the aid of a pneumatic actuator. In all the above versions, the valve seat is inclined at an angle of about 40 ° in the direction of the fluid flow. The direction of the flow is determined by the design of the valve (process valve and actuator).
