Ductile Iron Cast Steel Multiple Functional Pump Control Valve
Product introduction:
The multifunctional water pump control valve is an intelligent valve installed at the pump outlet of the water supply system and other water supply systems in high-rise buildings to prevent medium backflow and water hammer phenomena. This valve combines three functions: electric valve, check valve, and water hammer eliminator.
The multifunctional water pump control valve can effectively protect the safety and reliability of the water supply system, and integrate the technical principles of slow opening and slow closing to eliminate water hammer, preventing the occurrence of water hammer when starting and stopping the pump. Simply operate the water pump motor on/off button, and the valve can automatically open and close according to the water pump operating procedures, it is with high flow rate and low pressure loss.
Product technical parameter:
| Nominal Diameter DN (mm) | 50~300 | |
| Nominal Pressure PN (MPa) | 1.6/2.5 | |
| Test Pressure (MPa) | Strength (water) | 2.4/3.8 |
| Enclose (Water) | 1.8/2.8 | |
| Open and close pressure difference | ≤0.1MPa | |
| Working temperature | 0~80℃ | |
| Medium suitable | Water | |
Product features:
1. High safety and reliability. It has three measures to eliminate water hammer: quick closing, slow closing, and energy absorbing chamber, and the action is completely interlocked, without causing any misoperation.
2. No operational control required. When the water pump starts and stops, cleverly use the medium and pressure difference at both ends of the valve as the driving medium and control power, so that the valve automatically operates according to the requirements of the water pump operation regulations.
3. No need for professional debugging. The valve action is not affected by the liquid level difference, outlet pressure, and changes in water pump flow rate, and has a wide range of adaptability.
4. Basically no maintenance required, long lifespan.
5. The energy-saving effect is significant. By utilizing the pressure at the inlet end to enter the lower chamber to support the weight of the diaphragm pressure plate and valve stem, the resistance loss is minimal.
