Kunkle 19 Continuous By-Pass Relief Valve

 

Hand wheel for easy adjustment within spring ranges.

The Kunkle 19 is a non-code bronze liquid relief valve designed for overpressure relief of pumps, tanks, lines and hydraulic systems.

A common application in the water industry is to regulate system pressure while pumps must be run continuously during periods of bypass and maintenance on water tanks. Excess water capacity from the pumps is diverted through the valve to provide constant system pressure.

The valve disc is designed to re-seat when system pressure is relieved. To minimize water leakage we recommend the set pressure be 10- 15% above normal system operating pressure or 5 psi, whichever is greater.

The valve body and disc are made of bronze and the spring is stainless steel. A feature of the Kunkle 19 is it can be disassembled for inspection without removing it from the piping. Inlet connection is NPT(M) and the discharge or outlet port is NPT(F). Rated for service up to 300 psi and 406°F.

When installing a Kunkle 19 valve use Teflon® tape, not pipe dope, and mount in a vertical, upward position.

When ordering, from the chart below select the spring pressure range and the actual pressure setting within that range which is best for your application. That setting is what will appear on the nameplate.
