Description of Valve Safety Relief 50B-4KG1
The Cla?Val Model 50B?4KG1 (globe) or 2050B?4KG1 (angle) is a pilot?controlled pressure relief valve specifically designed for fire protection systems. Its primary function is to maintain constant pressure in the pump outlet line during startup and when pressure loads change rapidly. When water demand decreases, the valve opens to divert the pump output to the outlet, allowing the pump to be shut off without causing pressure surges in the system.
