Festo VZXA pneumatically actuated angle seat valves

Feb. 10, 2023

The Festo VZXA family of pneumatically actuated angle seat valves delivers installation, maintenance, operational, and inventory benefits thanks to a modular design.

When a VZXA actuator is removed for maintenance or changeover, for example, the stem, seat and seal stay inside the valve body, allowing the process system to remain pressurized. In applications containing hazardous materials, those materials reside safely within the system. Reinstalling the actuator is simply a matter of screwing it into the valve body. The actuator does not have to be pressurized, which eliminates strain on the stem, seat and seal, and lowers the potential of damaging the valve seat.

Modularity lends itself to valve body repair as stem, seat and seal are individual components with readily available replacement parts. The valve family’s standardized design ensures VZXA actuators are all compatible with every valve body in the family. The universal fit between actuators and valve bodies simplifies ordering and inventory management.

An online valve configurator enables the correct valve for the application to be specified and ordered in a matter of minutes. Normally open, normally closed, and double acting actuators are available. Line connections include threaded, sanitary clamp and welded end. Valve body materials include stainless steel and brass. Actuator bodies are stainless steel or polymer. Each VZXA actuator has an optical indicator showing valve position.
