One,Multi-functional pump control valveUsage:
The JD745X-10/16/25/40/64/100C High-Pressure Multi-functional Water Pump Control Valve is installed in systems for water abstraction, conveyance, submersible, and wastewater pump rooms in the municipal, construction, steel, metallurgical, petroleum, chemical, gas (natural gas), food, power stations, and nuclear power industries. It integrates the functions of electric valves, check valves, and water hammer eliminators into one unit, effectively enhancing system safety and reliability, and meeting the requirements for system automation control. The Multi-functional Water Pump Control Valve is a pressure control valve, consisting of a main valve and its accessories such as conduits, guide valves, needle valves, ball valves, and pressure gauges. Depending on the purpose, function, and location, it can be transformed into remote-controlled float ball valves, pressure-reducing valves, slow-closing check valves, flow control valves, pressure relief valves, hydraulic-electric control valves, and water pump control valves. This type of valve should generally be installed horizontally in pipelines.
Section 2: Features of the Multi-functional Pump Control Valve:
High safety and reliability. Equipped with three water hammer mitigation measures: quick closure, slow closure, and energy-absorbing cavity, and operates with complete interlock, preventing any false operation.
2. No operational control required. When the pump starts or stops, ingeniously utilizes the medium and pressure difference at both ends of the valve as the driving medium and control power, causing the valve to automatically act in accordance with the pump operation procedures.
3. No professional adjustment required. The valve operation is unaffected by the difference in liquid levels, water pressure, and changes in pump flow, with a wide range of adaptability.
4. Virtually maintenance-free with a long lifespan.
5. Significant energy-saving effect. Utilizes the pressure at the import end to support the weight of the diaphragm and valve rod in the lower cavity, resulting in minimal resistance loss.
