TDV Valves

Combination pump discharge valve functioning as a shut-off, check, and calibrated flow balancer. Available in sizes 1-1/2” through 12” with cast iron body. Threaded or flanged ends.

The unique quarter-turn TDV/TSV design offers backflow protection throughout a wide range of system balancing settings. Upon closing, the plug rotates to block the downstream port of the valve allowing pressure to equalize around the clapper so that it closes with little resistance. Final closing is accomplished by the plug camming against the backside of the clapper. The most satisfactory closure is accomplished by turning the plug to the normal tight fit, then bumping the plug lightly.
