Product Overview

It is installed on the outlet pipeline of water pumps in high-rise building water supply systems and other water supply systems to prevent medium backflow, water hammer and water shock. This single valve integrates the functions of an electric valve, a check valve and a water hammer arrester, which can effectively improve the safety and reliability of the water supply system.

Main Features

• Integrates functions of electric valve, check valve and water hammer arrester.
• Prevents medium backflow, water hammer and water shock.
• Enhances safety and reliability of water supply systems.
• Suitable for outlet pipelines of pumps in high-rise building and other water supply systems.

Working Principle

1. When the pump starts, the valve opens gradually via electric control to avoid water flow impact.

2. During normal operation, it allows medium to flow forward and stops backflow (like a check valve).

3. If water hammer occurs, the valve quickly adjusts internal pressure to suppress pressure fluctuations.

4. When the pump stops, the valve closes slowly to prevent backflow and secondary water hammer.

Structural Features

• Adopts an integrated structure, combining electric control unit, check mechanism and water hammer suppression component.
• Equipped with a precise electric actuator for stable opening and closing control.
• Features a built-in backflow prevention structure to avoid reverse medium flow.
• Has a pressure adjustment component to quickly respond to water hammer and stabilize pipeline pressure.

Maintenance

• Check hydraulic oil level annually
• Test closing time every 6 months
• Inspect disc and seat for wear during system shutdowns
• Lubricate adjustment mechanism yearly
• Verify proper operation after system pressure changes
