Casing Relief Valve

Description

Our Cla-Val casing relief valve is a direct-acting, spring-loaded, diaphragm-type valve engineered for reliable overpressure protection in fire protection systems. Designed for precise operation, it opens and closes within very close casing limits to ensure system stability and safety.

This valve can be installed in any position without affecting performance. A unique feature of its design is the removable bottom plug, which may be reinstalled in the inlet to create an angle pattern flow path, offering flexibility for a variety of installation needs.

In fire protection applications, the casing relief valve plays a vital role in trimming excess water casing and preventing dangerous build-up within the distribution network. When system casing rises above the spring setting, the valve discharges to the atmosphere, relieving excess casing and protecting pumps, piping, and other downstream components. By maintaining consistent operating casing, it helps ensure reliable system performance and compliance with fire safety standards.

Built for durability and precision, this casing relief valve is trusted by engineers, contractors, and facility managers to safeguard critical fire protection infrastructure.
