Angled Seat Valve

Festo’s VZXA angled seat valve comes with a modular design. VZXA valves consist of the angled seat body, a piston or diaphragm actuator, a sealing cartridge and a visual position indicator. The valve body and actuator modules are self-contained functional units that can be freely combined thanks to standardized interfaces, which makes them easy to assemble and maintain and allows for the actuator to be replaced during maintenance without opening the (unpressurized) piping. The patented sealing system, which prevents leakage of the medium into the actuator, is designed as a compact cartridge that if need be, can be changed easily and quickly without using special tools. The large optical position indicator is standard and comes with a transparent polyethersulfone (PES) hood, allowing VZXA valves to be used trouble-free in chemically aggressive environments. Actuators come in three sizes (46mm and 75mm piston type and 90mm diaphragm type), single acting (NC or NO) or double acting (DA). Valve bodies are available in seven, 2/2-way nominal sizes from DN13 (½”) to DN65 (2½”), with threaded, clamped and welded connections. VZXA also is ideally suited for designing customized valve blocks.
