Double Regulating Valve (DRV) – Ductile Iron

  • Y-Pattern globe valve with a characterised throttling disc
  • The Double Regulating feature allows the valve to be used for isolation and to be reopened to its pre-set position to maintain required flow rate
  • In two unit systems, the DM921 has sufficient authority to regulate flow in circuits incorporating a flow measurement device
  • The valve opening may be set to control flow at a pre-determined rate
  • Fitted with 2 x 1/4" BSPT plugs for conversion to DM931 if required
  • Operation of the valve is by means of a hand wheel incorporating a micrometre device
