TDV 4

This 4 inch triple duty valve, Model TDV, is a triple function valve used in flow measurement applications to eliminate the requirement of a hand-tight shutoff valve, a check valve, and a flow control valve on the pump system. It consists of ductile iron body construction with grooved ends and anti-rotation lugs, two NPT connections on each side of the valve seat, two brass metering ports with non-slam silent check valve and gasket cap, brass drain tap, bronze disc, stainless steel valve stem, and stainless steel spring.
