The Waterous Intake Relief Valve system is designed to act as a safety valve by "dumping" excess pressure from the inlet side of the pump. The Discharge Relief Valve provides sensitive pump control to protect firefighters from sudden pressure surges resulting from changes in discharge flows from the pump.
Discharge Relief Valve
Designed with a ‘‘built–in–memory’’, this system has a wide continuous range of pressure control from a minimum of 75 to a maximum of 300 psig (5.2 to 20.7 bar) depending upon pump performance characteristics, and may be put in or taken out of operation without disturbing the pressure setting. This lets you leave the system at a pre–set ‘‘ready–to– use’’ pressure setting. The Waterous discharge relief valve system incorporates two separate units, a panel mounted pilot valve which controls the operation of the relief valve proper, and the relief valve which is normally mounted on the pump.
Intake Relief Valve
The Waterous Intake Relief Valve system incorporates two separate units for ultimate flexibility in installation and operation: the pilot valve and the main valve. The pilot valve controls operation of the main valve and can be panel mounted to be easily field adjusted for varying operating conditions, or compartment mounted and preset for a specific pressure. It includes a removable strainer and removable needle valve for easy servicing.
