Detail / Feature / Application

Hydraulic Self-operated Control: Utilizes the pipeline's own water pressure and differential pressure to open and close the valve, requiring no external power, ensuring safety and energy efficiency.
Diaphragm-Driven Responsiveness: The rubber diaphragm senses pressure changes to precisely control the disc movement, offering rapid response.
Accurate Pressure Regulation and Stabilization: Effectively reduces and stabilizes upstream pressure, protecting downstream equipment.
Reliable Safety Pressure Relief: Automatically opens to relieve pressure when overpressure occurs, and closes when pressure normalizes, ensuring system safety.
Effective Water Hammer Suppression: Mitigates water hammer impact by slowing the closing process, safeguarding pipelines and pumps.
Multi-Functional Integration: By combining different pilot valves, it achieves various control functions such as flow, pressure, and level control.
Low Flow Resistance and Energy Consumption: Full-bore design ensures unobstructed flow and minimal resistance, improving energy efficiency.
Excellent Sealing Performance: Soft sealing structure ensures tight closure and minimal leakage.
Strong Pressure Adaptability: Adjusting pressure settings is easily achieved by replacing springs, making it suitable for various working conditions.
Easy Installation and Maintenance.

Used at the pump outlet of high-rise buildings or other water supply systems, it prevents backflow and reduces water hammer, achieving safety and quiet operation.

This check valve prevents water hammer and water shock, achieving a slow-closing and silencing effect. It features adjustable opening and closing speeds. The optimal opening and closing speed can be adjusted on-site during pump startup or operation.
