Product Overview

This intelligent valve is installed at the outlet of the water pump in the water supply pipe network system to prevent medium backflow, water hammer and water shock. It combines the three 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

• Multi-functional integration (combines check, shut-off, and water hammer prevention).
• Piston-driven, reliable operation.
• Suitable for water supply pump outlets.
• Automatically adjusts to working conditions.
• Enhances system safety and stability.

Working Principle

It mainly relies on the piston structure to sense the pressure changes of the medium (water) in the pipeline. When the pump starts, the water pressure pushes the piston to move, opening the valve disc to realize water supply. When the pump stops, the water pressure drops, and the piston resets under the action of the spring, closing the valve disc quickly to prevent water hammer and backflow, thus protecting the water pump and pipeline system.

Structural Features

• It has a core piston structure that is sensitive to pressure changes, serving as the key component for valve opening and closing control.
• It is equipped with a return spring to ensure the piston resets promptly when the pump stops, enabling quick valve closure.
• The valve body adopts a design suitable for water medium, with a built-in valve disc that matches the piston to effectively prevent backflow and water hammer.
• It integrates multiple functions (such as check, pressure regulation, and water hammer prevention) into a single structure, eliminating the need for additional separate valves.

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
