Cla-Val - Hydraulic Pressure Control Valves - 55B-60 Pressure Relief Valve ***
The 50 Series Pressure Relief Valve is designed to maintain constant upstream pressure within close limits. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. In addition to surge relief, this valve can be used for pressure relief, pressure sustaining, back pressure or unloading functions in a by-pass system.
The Cla-Val Model 55B-60 Pressure Relief Valve is a direct-acting, spring-loaded, diaphragm type relief valve and is typically used in high-rise building water systems to prevent pressure build-up whenever line pressure exceeds the setting of the spring.
Installed downstream of the pressure reducing valves, the 55B-60 relieves excess pressure to the atmosphere to prevent damage to the distribution network.
