The sensing component of the multifunctional water pump control valve is a diaphragm, which has a smaller flow resistance coefficient than diaphragm and piston types.
○ Nominal pressure: 1.0MPa, 1.6MPa, 2.5MPa
○ Minimum operating pressure: ≥ 0.04MPa
○ Slow closing time: 3-60s (adjustable)
○ Applicable medium: water
○ Medium temperature: 0-80 ° C
○ Valve body material: ductile iron, carbon steel, stainless steel
○ Nominal diameter: DN50-DN300mm
○ High reliability in eliminating water hammer. The opening and closing of the slow closing device are interlocked with the main penalty plate; Automatically achieve quick closing, unaffected by fluctuations in the actual flow rate and head of the water pump, without the need for quick closing time calculation; No need for on-site adjustment by professional technicians; No need for any electrical appliances or hydraulic components, with fewer fault points.
○ The effect of eliminating water hammer is good. Integrating the technical principles of quick closing, slow closing, and water hammer absorber to eliminate water hammer, reducing the pressure of water hammer when stopping the pump to the lowest limit.
○ The valve is easy to operate and maintain. Simply operate the on/off button of the water pump motor starter, and the valve will automatically open/close according to the water pump operating procedures. All key components are made of high-quality materials and require minimal maintenance.
○ Preventing water hammer impact during pump shutdown in high-rise building water supply systems
○ The outlet of the municipal water supply pump station is used for automatic opening and closing and slow closing check
Industrial circulating cooling water system ensures safe and stable operation of water pumps
○ Implement linkage control and overpressure protection for the outlet pipeline of the fire pump
○ Agricultural irrigation pump station prevents backflow and reduces pressure fluctuations in the pipeline network
The adjustable pressure reducing and stabilizing valve can automatically stabilize the inlet high pressure to the set outlet pressure
Electric control valves are used as opening and closing devices for pipelines, while solenoid valves control the opening and closing of the main valve, enabling remote and local control.
The micro resistance slow closing check valve adopts a double flap slow closing and streamlined flow channel design, with low resistance and smooth closing
