Festo’s new angled seat valve VZXA features field-friendly modularity
VZXA valves from Festo consist of the angled seat body, a piston or diaphragm actuator, a sealing cartridge and a visual position indicator.
MISSISSAUGA, ONT.—Festo’s new VZXA delivers everything the process sector requires in an angled seat valve. Its optimized bore passages enables extremely high flow rates of highly viscous media, liquids, gases or vapors.
Its sturdy steel body assures a long, reliable service life. And with virtually no dead spaces inside, a VZXA is quick and easy to clean inside and out.
What truly distinguishes VZXA, however, is its 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 for VZVA 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.
