Non-Slam Check Valves for Water Systems

Non-slam check valves are ideal for water systems where quiet operation and reverse flow protection are crucial. These valves are commonly used in factory utilities, municipal infrastructure, and clean water systems, especially in high-standard environments such as electronic manufacturing plants.

How It Works

Our non-slam valves use a spring-loaded disc that quickly closes in the axial direction, preventing fluid reversal and eliminating the shock of water hammer — essential in sensitive clean water systems.

Unlike conventional swing or lift check valves, non-slam check valves utilize a spring-assisted disc mechanism. This disc moves in the axial direction of the flow and is automatically pushed closed by the spring force as the forward flow slows down, long before the flow reverses. This ensures a quick, smooth, and silent closure, minimizing the risk of water hammer — a common issue in pump and high-pressure piping systems.

Typical Applications

• Clean water pipelines in electronics factories
• Municipal water and wastewater treatment
• Factory utility water systems
• Drainage and sewage infrastructure
