Festo’s angle seat valves VZXA can control media flows quickly and reliably. Their carefully thought-out product architecture and patented interface enable valve bodies and actuators to be freely combined.
Individual, function-tested modules simplify the replacement of actuators during conversion or maintenance. The patented seal system prevents the operating medium from leaking out.
This unique interface between the modules means that the actuators can be replaced without opening the piping.
The spindle seal is in the form of a cartridge. It comprises a stainless steel sleeve with a pre-tensioned domed seal packing consisting of PTFE sealing rings and can be replaced easily.
Angle seat valves VZXA comprise an angle seat valve body, a piston or diaphragm actuator and a visual position indicator. The flow-optimised valve body made of stainless steel is available in the nominal sizes DN15 – DN65.
Stainless steel actuators are available in three sizes and with the control functions NC (normally closed), NO (normally open) and DA (double-acting). The maximum operating pressure, depending on nominal size, is up to 30 bar.
Interfaces are provided, together with internal channels for the operating pressure to allow the subsequent addition of positioners and valve control heads.
