The JD745X Multi-functional Water Pump Control Valve is a hydraulic control device that integrates electric valve, check valve, and water hammer eliminator functions. It is mainly used at the pump outlet end of high-rise buildings, municipal water supply and drainage systems, fire protection systems, and industrial fluid transmission systems to prevent backflow of the medium and eliminate water hammer effects.

Core Features

‌Prevent Water Hammer: Through three stages of gradual opening, quick closing, and gradual closing, effectively suppresses pressure fluctuations generated during the start-up and shutdown of the pump, protecting the pipeline and pump.‌

‌Automatic Control: No external electrical control system required; valve operations are automatically completed with the start and stop of the pump.‌

Media unidirectional flow: The valve body arrow must align with the water flow to ensure unidirectional flow.

Structural Features

‌Dual control room structure: Diaphragm or piston design for quick closure to 90% of the opening to prevent backflow, with the remaining opening gradually closed by the combined action of water pressure.‌

‌Full-channel streamlined design: Low hydraulic loss, high flow rate, compact volume, and light weight.‌

Applicable scenarios

Pipe Size Range: DN40 - DN1600.

Operating Pressure: 1.0-2.5 MPa (standard type), 1.0-10.0 MPa (diaphragm type).

Medium Temperature: 0-150°C.

Installation Key Points

Filters must be installed before the valve, and it should be easy to drain.

Ensure the valve body arrow is aligned with the water flow direction during installation.
