KPRV and KBPV Relief Valves

The KENCO KBPV Back Pressure Valves are two-way relief valves designed to keep a constant pressure in the discharge lines of a chemical feed pump system. Constant pressure on the discharge side of the chemical feed (metering) pump prevents siphoning, ensuring proper operation of the pump and an accurate chemical dosage rate. KENCO KPRV Pressure Relief Valves are similar in design to KBPV Valves but are three-way valves that allow unrestricted flow through two ports and a third relief port designed to be connected back to tank. This configuration provides protection from over pressurization of the chemical feed systems lines and components by relieving the system pressure back to tank through the third port when the system pressure exceeds the KPRV’s set pressure.

Relief Pressure are factory set to 50 psig (3.44 bar) and can field adjusted from 15 to 150 psig (1.03- 10.34 bar).

Available with 1/4″, 1/2″, 3/4″ and 1″ port sizes in either female FNPT threads or Socket Weld connections.
