DUAL ‘s Pump Protection Valve has been designed and manufactured to provide protection against excessive fluid temperature rise, within the pump housing. Low flow conditions can cause flashing, cavitation, vibration, bearing failure and damage to mechanical seals and pump housing. The DPV valve is titted to the suction side of the pump. The valve can also be used to control or limit the pressure in a pipeline or vessel.
