1. With high driving force and suitability for high-pressure differentials: The piston structure provides ultra-large thrust, easily handling high-pressure differentials, large diameters, and high-flow conditions.
2. Strong contamination resistance: The large movement clearance reduces the requirement for medium cleanliness, making it adaptable to fluids containing微小颗粒.
3. Smooth opening and closing with water hammer prevention: Controlled pilot operation enables gradual opening and closing, effectively eliminating water hammer and protecting pipeline safety.
4. Precise control and diverse functions: Equipped with different pilot valves, it can achieve various functions such as pressure reduction, slow-closing check, constant flow, and pressure relief.
5. Excellent control for large diameters: Strong driving capability makes it suitable for high-pressure differential control in diameters of DN500 and above.
6. Robust structure and long service life: The metal body offers high pressure and wear resistance, ensuring stable and reliable performance with extended maintenance cycles.
It is primarily used at the outlet of pumps in large-diameter water supply pipeline systems to prevent backflow, water hammer, and water hammer phenomena as an intelligent valve.
This hydraulic control valve combines the functions of an electric valve, check valve, and water hammer eliminator, significantly enhancing the safety and reliability of water supply systems. The dual-chamber structure allows the valve to quickly close 90% after pump shutdown to prevent pump reversal caused by backflow, and then slowly close the remaining 10% to eliminate destructive water hammer. Piston-type valves offer reliable performance, high strength, and smooth operation, preventing water hammer during both pump start-up and shutdown.
