Triple Duty Valves

Series TDV Triple Duty Valves are triple function valves 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 a 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 valves and gasketed caps, brass drain taps, bronze disc, stainless steel valve stem, stainless steel spring, and optional flange adapters. Series TDV provides a quiet system operation and is ideal in single, double, and vertical in-line pump applications.


  • For use on single, double, and vertical in-line pumps
  • Combines three functions: positive shutoff, silent check, and flow control into a single valve
  • Can be changed from straight pattern to angle pattern in the field
  • Saves on space, installation time, and system cost
