The micro-resistance slow-closing check valve is an automatic check valve that combines low flow resistance with slow closing to prevent backflow hammer. It not only offers minimal opening resistance during forward flow but also effectively eliminates or significantly reduces water hammer pressure waves during valve closing, protecting piping systems. It is widely used in piping systems for water supply and drainage, fire protection, and industrial circulating water, preventing backflow and reducing pipeline shock.

Key Features
Excellent Water Hammer Resistance:
This core advantage features an adjustable slow-closing function that effectively eliminates destructive water hammer, protecting pumps and piping systems.
One-Way Flow Protection:
Valve ensures fluid flows in one direction and prevents backflow.
Slow-Closing Mechanism:
Gradually closes the valve to minimize water hammer and system stress.
Durable Material Construction:
Stainless steel or carbon steel body provides long service life and corrosion resistance.

Low Maintenance:
Micro-resistance mechanism requires minimal upkeep and ensures consistent performance.

Typical Applications
Water supply and distribution pipelines
Pump discharge lines
Wastewater and sewage systems
Industrial fluid pipelines
Fire protection and HVAC systems

Advantages
Prevents backflow effectively
Reduces water hammer and pressure surges
Corrosion-resistant and durable materials
Smooth and reliable operation
Compact design and easy installation
Long-term consistent performance
