When installed in a line between an upper zone and a lower area of heavy demand, the valve acts to maintain desired upstream pressure to prevent "robbing" of the upper zone. Water in excess of pressure setting is allowed to flow to an area of heavy demand, control is smooth, and pressure regulation is positive.
This fast opening, slow closing relief valve provides system protection against high pressure surges on pump start up and pump shut down by dissipating the excess pressure to a safe location and dissipating the excess pressure to a safe location.
The Pressure Reducing Valve (PRV) automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure.

Cla-Val deluge fire protection valves deliver top of the line performance and reliability. We offers these valves in a range of exotic materials that are uniquely suited to seawater service, including nickel-aluminum-bronze, super duplex stainless steel, and titanium. We have the right fire protection valve for any system and any location.
Cla-Val deluge fire protection valves can be operated hydraulically, pneumatically; remote control options are also available.
Every Cla-Val fire protection valve is designed for easy installation, minimal maintenance, and superior durability in harsh working conditions, such as seawater and other potentially corrosive environments.
Tube diaphragms are manufactured from homogenous nitrile rubber for drip-tight seals. Valve components are UL/ULC listed and/or FM approved (varies by model).All Cla-Val deluge fire protection valves are 100% made in the USA.
