The Cla-Val Pacific 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 pressure reducing valves, the 55B-60 relieves excess pressure to atmosphere to prevent damage to the distribution network.
