    Ball type check valves are produced in three sizes: 10-32, 1/8" NPT and 1/4" NPT. They are available in both brass and stainless steel and are suitable for use with liquids or gases. Free flow occurs in one direction only; reverse flow is prevented. All valve seats are metal to metal construction. Minor amounts of seat leakage can be expected. See General Specifications.
