Choosing between a wafer check valve and a lift check valve can save you money and prevent operational problems. Here is a detailed comparison to help you decide which type to order for your project.
The wafer check valve fits between two pipe flanges. Its ultra-short face-to-face length (often 1/3 of a flanged valve) makes it ideal for tight spaces.
Advantages: Low weight, low check valve price, easy installation.
Limitations: Not suitable for very high pressure (usually ≤ PN40).
Best for: Water, HVAC, air compressors, and space-limited areas.

Buy a wafer check valve when you need a low cost check valve for clean water, HVAC, or air, and space is tight.
Buy a lift check valve for high-pressure steam or corrosive chemicals where tight shut-off is critical.
Where to order? Many check valve suppliers offer both types. Request a check valve catalog with prices to compare. For large projects, wholesale wafer check valve pricing can reduce costs significantly.
