Automatic Recirculating Valves

Pump protection valves ensure minimum flow through a pump. By doing so the pump is protected against overheating and cavitation which can cause damage. In case the process requires no flow or a small quantity of the pumped liquids, the pump protection valve automatically returns the required minimum flow via a bypass back to the pump.
