I would like to inquire about the usage of the multi-functional water pump control valve JD745X-10
Thread Content
A multi-functional pump control valve of the JD745X-10 model is installed at the outlet of the circulating water pump. I would like to ask: 1. Can it replace the outlet electric valve in order to achieve automatic control after the pump starts and stops? 2. What problems may arise during actual use? 3. Which is better, domestic or foreign?
This is a hydraulic control valve (or slow-closing check valve), which prevents the rapid closure of a regular check valve when the pump stops, thereby avoiding severe water hammer effects. It cannot replace the shut-off valve at the pump outlet. A hydraulic control valve is a valve that uses the pressure of the fluid in the pipeline as power to open, close, and regulate. The pilot valve operates in response to changes in the liquid level and pressure of the medium; it can open or close its own small valve opening based on changes in the downstream pressure, thereby altering the pressure level in the control chamber above the diaphragm (piston) and controlling the adjustment position of the main valve’s disc. It is commonly used in domestic water supply, fire protection systems, and industrial water supply systems.
According to the information, it seems to incorporate the functions of an electric valve; but is it still necessary to install an electric valve on-site in reality?
