Product Description

Multifunctional diaphragm type pump control valve is installed in the high-rise building water supply system as well as other water supply system of the pump outlet, to prevent the media back, water hammer and water hammer phenomenon intelligent valve. The valve with electric valve, check valve and water hammer eliminator three functions, which can effectively improve the safety and reliability of water supply system. And will slow opening, fast closing, slow closing to eliminate the technical principle of the integration of water hammer, to prevent the opening of the pump water hammer and stop the generation of water hammer. Only need to operate the pump motor Rev. And close button, the valve can be automatically realized in accordance with the operating rules of the pump to open and close, flow, pressure loss. Diaphragm type 600 - caliber valve.

The Model JD745 is popularly used in pump station of water supply & transport system and sewage treatment, including municipal projects, high-building, mining industry and factories etc. It works as an multi-purpose valve integrating the functions of electric valve, check valve and pressure surge eliminator. As a result, it has a high security and dependability to meet the requirements of system automation.

This valve is provided with three types of structure to eliminate pressure surge including quick shut, slow shut and absorbing chamber, with actions completely linked without errors. When pump is started or stopped, it can use mediums at the two ends of valve and their pressure difference as driving medium and control;ing power, making valve automatically interconnected according to the operating regulations of the pump, and not affected by pipeline pressure and flow rate.
