Festo VZXA angle seat valves

Festo has introduced a highly adaptable angle seat valve, the VZXA. Featuring a modular product architecture, its wide variety of valve bodies and actuators can be freely combined for configuration flexibility. Engineers designing process applications in industries such as food and beverage, chemical, biopharma and industrial water can use the VZXA to control media flows.

The VZXA consists of an angle seat valve body, a piston or diaphragm actuator and a visual position indicator. The robust, flow-optimised valve body is made of easy-to-clean stainless steel and available in nominal sizes DN15 to DN65, and connection variants include threaded, clamped or welded. Its high flow rate makes the VZXA suitable for highly viscous media: liquids, gases or vapours.

Stainless steel actuators are available in three sizes, with the control functions NC, NO and DA (double-acting). The standardised interface between modules simplifies installation, allowing actuators to be replaced without having to remove the entire valve. Separation of valve bodies and actuators also makes installation of valves in pipelines easier and faster. The spindle seal is in the form of a cartridge, meaning it can be replaced simply without need for special tools.

The VZXA is quick and easy to clean inside and out as it has virtually no dead spaces. Its modular construction means the actuator can be easily removed and sterilised in an autoclave, for instance.
