1/2" MPT Thermal Relief Valve 190 Degree Maximum General Pump

Protects the pump from damaging heat buildup while it is in bypass mode. The thermal relief valve, sensing a rise in temperature opens and discharges a small amount of heated fluid. This allows cooler water to enter the system and cool the pump. When the gun is discharged the cooler water will cause the valve to close immediately.

The most consistent temperature range on the market.

Quickest response to rising temperature.

Less stress on the pump. 

Shorter overall length.

Most cost-effective thermal protector on the market.

Mounts easily in the pump manifold, inlet water supply, or bypass loop plumbing.

Hose barb: 90 1/4" (You do not need to install a hose on the barb. It is better to see this orifice leaking as it presents a problem when it is leaking, and the problem must be dealt with as soon as possible.)

Weight: 1.5 oz.
