CHECK VALVE APPLICATION
Sometimes referred to as non-return valve, check valves prevents back-flow, constantly keeping flow in one direction. Check valve are designed to close quickly and automatically with positive shut off in either horizontal or vertical (flow up) pipe runs. Inherently, swing check valves have a low pressure drop and are best suitable for velocity applications. Our enclosure design allows check valve to close completely and remain closed even with no flow when installed in a pipe run.
