Cla-Val - Fire Protection - Pressure Relief Valves - 50-49 Pump Start Pressure Relief Valve
The Cla-Val Pressure Relief Valves are designed specifically for fire protection pumping systems and are available in a variety of configurations and end connections.
- 50 Series Pressure Relief and Pump Suction Control Valves used in conjunction with fire pumping systems to relieve excess pressure, control pump draw or prevent surge, depending on the configuration and pilot controls.
- The 55L-60 is a direct-acting, spring-loaded relief valve that can be installed in any position in a fire sprinkler piping system to prevent pressure build-up that could damage the pipeline.
- 750 Series Pressure Relief Valves are also used to relieve excess pressure, as well as to maintain constant pressure at the pump discharge.
- 850 Series Tubular Diaphragm Fire Relief Valves provide fast-acting deluge service and are fitted with integral cavitation protection.
Cla-Val Pressure Relief Valves are not only durable and reliable, but they are also backed by the more than 80 years of control valve expertise and the best customer service in the business.
The Cla-Val Model 50-49 Pump Start Pressure Relief Valve provides pump and pipeline protection during pump start sequence and pump operation when discharge pressure rises to unsafe levels.
Should the discharge pump pressure continue to rise due to little or no system demand, the normally closed pilot provides overpressure protection by relieving excess pressure to the atmosphere as long as the relief valve inlet pressure is greater than the pilot pressure setting. This pilot has various adjustable spring ranges to meet the system pressure requirements.
