The Zurn Wilkins 6-inch ZW209FPX is a pilot-operated pressure reducing valve specifically designed for fire suppression systems. It ensures stable downstream pressure by modulating the main valve, automatically sealing shut once the pilot setting is reached, preventing downstream damage. Constructed from ductile iron with internal and external epoxy coating, this valve offers superior corrosion resistance and is FDA approved. It comes standard with isolation valves and pressure gauges for easy maintenance and is certified to NSF/ANSI/CAN 61 and ANSI/AWWA C530 standards. This valve features ANSI Class 150 flanged connections.

Connections
The 6" ZW209FPX valve is designed with ANSI Class 150 flanged connections.
It will directly connect to existing piping systems that also utilize 6-inch ANSI Class 150 flanges.
Ensure proper alignment and gasketing when installing into your fire suppression system to maintain a secure, leak-free connection.
The 6" ZW209FPX Pressure Reducing Valve is a pilot-operated valve designed for fire suppression systems, ensuring stable downstream pressure even with high flow rates. Its reactive pilot assembly allows the main valve to modulate between closed and open for a constant downstream pressure and automatically seals shut upon reaching the pilot setting to prevent downstream damage.
