Dual Valve Controller

DVC – The eDART Dual Valve Controller (DVC) is used to control two valves which act in parallel with a single 4 – 20 mA signal from the control room. Typically, this would be two parallel internal dart valves or the external Dual eDart but this device has been used in as diverse applications as two desuperheaters in parallel (a desuperheater is used to control the amount of cooling water to bring saturated steam down to with a few degrees of saturated temperature).
