Steam traps do not always require check valves, but in certain applications, such as with PRIMUS Sterilizers, installing a swing check valve like the VALVE, CHECK, SWING, BR, 1/2″ can help prevent backflow and water hammer. The decision depends on system design, operating pressures, and specific safety requirements. Proper placement ensures optimal trap performance and equipment protection.
