The Steam Trap Test Valve 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.

The WDF Diffuser was specifically designed to cushion the discharge from steam or air traps. They work to suppress the high velocity discharge often associated with blast-type steam traps in order to reduce noise, erosion and waterhammer. This compact unit is made from Stainless Steel. It is available in 1/2" and 3/4" NPT and SW connections.
