Frequently Ask Questions

What Is a Non Slam Disc Check Valve?

A Non Slam Disc Check Valve is an automatic check valve designed to prevent reverse flow while closing rapidly enough to minimize pressure surges and water hammer.

How Does It Work?

During forward flow, fluid pressure pushes the disc away from its seat. As flow velocity decreases, the spring pushes the disc toward the closed position before significant reverse flow develops.

Which industries commonly use Non Slam Disc Check Valves?

These valves are widely used in water treatment plants, wastewater systems, HVAC, chemical processing, oil & gas, power plants, fire protection systems, and industrial pumping applications.

Why Is It Called Non-Slam?

It is called non-slam because the valve is designed for controlled, rapid closure that helps prevent the disc from violently slamming against the seat.

What is the difference between a Non Slam Disc Check Valve and a Swing Check Valve?

A Non Slam Disc Check Valve uses a spring-loaded disc for instant closing, while a Swing Check Valve uses a hinged disc that may close more slowly, increasing the risk of water hammer.

How do I choose the right Non Slam Disc Check Valve?

Selection should be based on pipe size, pressure rating, operating temperature, flow rate, installation position, body material, and process media to ensure optimum performance.
