The Mini-Check (M1-M8) is designed for minimum pressure drop.

The three-piece construction permits many combinations of end fittings, which makes the valve adaptable for nearly every application. The Mini-Check is available with 1/8, 1/4, and 3/8 inch pipe threads, both male and female. 

It can also be supplied with a 1/8" (3.175 mm), 1/4" (6.35 mm), or 3/8" (9.52 mm) tubing end on one side and with a pipe thread end on the other. Combinations of male and female threads are also available. The Mini-Check can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
