How to choose
- Swing vs. spring: swing checks have low pressure drop and suit horizontal water lines; spring (inline, Y-spring, barrel) checks close faster, work in vertical lines and cut water hammer.
- Material: brass for water and air, lead-free brass for potable water, stainless for corrosive or food and washdown service, PVC for chemical, irrigation and drain lines, ductile iron wafer checks for large flanged lines.
- Connection: match FNPT threads, sweat (solder) ends, PVC slip (glue) sockets or flanges to the pipe you already have.
- Flow direction: every check valve has a flow arrow; install it pointing away from the pump or source.
- Compressors: use a compressor tank check valve sized to the pump discharge and tank inlet threads.
