Differential Pressure Control Valve
DN25~DN50
DN50~DN150

◆Asjust automaticaly using the pressure of the user. Automatically eliminate the flow changes induced by the residual pressure head of the pipe network and the fluctuation of pressure. Keep the inlet and outlet pressure constant. Stabilize the system operation.
◆ Buit-in diaphragm capsule, small-sized valve body, easy installation.
◆ Absorb fluctuation of differential pressure in external network.
◆ Higher control precision, better stability, more energy saving.
◆ No balancing debugging after valve installation. Debugging cost is greatly reduced.
◆ Noise reduced. Differential pressure limitation make ensure that the differential pressure through the control valve won’t increase even in the case of sub-load. That will help to reduce the noise.
◆ Ductile iron with rust-proof treatment provides elegant appearance.
