รายละเอียด Variable Orifice Double Regulating Valve (DRV) Crane 2 1/2 inch Ductile 065,PTFE End Flange, PN16 Model DM931

  • These are Y-pattern globe valves with two P84 pressure test points to provide flow measurement, control and isolation.
  • The Double Regulating feature allows the isolator valve to be applied and re-opened to a pre-set position to maintain the desired flow rate.
  • Single-unit supply means fewer joints on site
  • It is primarily used in injection or other circuits that require double control valves for system balancing.
  • The flow measurement accuracy is ±10% at the fully open position of the valve.
  • Some decrease in accuracy occurs at partial opening of the valve according to BS 7350.
