Steam Trap Test Valves

With WSTTV Steam Trap Test Valves installed downstream of the trap and in the open position, the steam trap discharges normally. A quarter-turn of the handle repositions the specially designed ball and diverts the trap discharge through a port on the bottom of the valve. Discharge can then be observed and assessments made regarding the operation of the steam trap.

Description

Steam Trap Test Valves offers simple, immediate, and visible diagnosis of any steam trap. Turning the handle 90° to the “Test” position will direct flow of steam trap out the test port for visual evaluation of discharge.

Steam Trap Test Valves need to be mounted on the outlet side of the steam trap. Care should be taken to ensure that the discharge port will be positioned in such a manner so as to avoid danger to personnel. NOT AN ISOLATION OR STOP VALVE.

Test Valves can be installed downstream of any steam strap to visually inspect the discharge of condensate from the traps. Available in stainless steel up to 1″ in size.
