discharge valve functioning as a shut-off, check and calibrated flow
balancer. Available in sizes 1½” through 12” with cast iron body.
Threaded or flanged ends.
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 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 a normal tight fit, then bumping
the plug lightly.
