Pump bypass valves give you on/off control of the required minimum water flow for cooling of the centrifugal pumps when the main descale system does not have a demand for water spray. With this control, you can eliminate the bypass flow when the water is required for the descale system. These valves are located at the pump discharge.

The versatility of Hunt Valve’s 2- and 3-inch descale spray valves makes them the perfect choice for use as pump bypass valves designed as normally open/bias open for fail-safe operation and pump protection.
