1. Operating pressure must NOT exceed 200 psig.
2. All check valves are cleaned for oxygen service before ship-
ment. If they are used for oxygen service, do NOT use
oil or grease since they ignite easily and burn violently
under pressure in the presence of oxygen.
3. Periodically test the check valve for leakage between the
ball and seat by a reverse flow procedure using Leak Test
Solution suitable for oxygen service, such as P/N 998771(8
oz. container). If there is leakage, replace parts shown be-
low or replace the entire check valve.
