How to Choose the Right Check Valve for Different Media?

When selecting a check valve, the type of medium (fluid or gas) plays a crucial role in ensuring optimal performance and longevity. Here¡¯s a quick guide to help you pick the right valve for your application:

1.High-Viscosity Media (Crude Oil, Heavy Fuel, etc.)

Lift Check Valves may struggle due to resistance.

Swing Check Valves (hinged disc) or Ball Check Valves (rolling ball mechanism) are better¡ªthey open and close more smoothly under thick fluids.

2.Clean Media (Steam, Water, etc.)

Lift Check Valves work well because their sealing surfaces stay intact with minimal wear.

Ideal for steam systems, where media is free of particles.

3.Media with Solid Particles (Wastewater, Slurry, etc.)

Dual-Plate (Wafer) Check Valves ¨C Simple disc design resists clogging.

Ball Check Valves can handle small particles but may jam with larger debris.

4.Corrosive Media (Acids, Alkalis, etc.)

Diaphragm Check Valves ¨C Isolate media from metal parts, offering excellent corrosion resistance.

Choose stainless steel, PTFE-lined, or plastic valves based on chemical compatibility.
