Product Overview

This product is a hydraulic control assembly device that strictly restricts water in the pipeline to flow in only one direction. Its function is to prevent the medium in the pipeline from flowing backward under all operating conditions, so as to avoid backflow pollution.

Main Features

• Integral structure design for compact size and easy installation.
• Strictly prevents medium backflow in pipelines under all working conditions.
• Effectively avoids backflow pollution to ensure fluid supply safety.
• Suitable for hydraulic control scenarios requiring one-way fluid flow.

Working Principle

1. When the medium flows forward normally, it pushes the internal check components open, allowing smooth passage through the device.

2. If the medium tends to flow backward (e.g., due to pressure changes), the check components automatically close under the reverse pressure.

3. The closed check components form a tight seal, blocking the reverse flow path of the medium.

4. This one-way opening and closing mechanism ensures no medium backflow, thus preventing backflow pollution.

Structural Features

• Adopts an integral structure, integrating all functional components into a single unit for space-saving installation.
• Equipped with high-sealing check components (e.g., check valves) to ensure reliable one-way flow control.
• Features a robust hydraulic control system that coordinates component movement to respond to flow direction changes.
• Has a simplified internal flow path design, reducing medium resistance and improving overall operating efficiency.

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
