  • Introduction
  • Specifications
Electric two-seat adjusting valve use single-phase AC 220V as power. Receive 0~10mA DC signal, automatically control the opening of valve, achieve continuous regulation of pressure、temperature、flow、liquid level and other process parameters. It is an importance part of automatic regulation system, widely used in electric、metallurgy、petroleum、chemical、light industry、food and other automatic control system
Structure principle
Made up of DKZ series of linear travel electric actuator and two-seat valve
Electric adjusting valve input DC current signal of regulator, enlarged by servo amplifier and then drive actuator, produce axial thrust, drive adjusting valve, cause the change of media flow, for adjusting all thermal parameters of systems. Same time, actuator produce a displacement signal, keep adjusting valve at a corresponding position of input signal, complete servo regulation
After equipping DFD-09 electric operator, achieve manual and automatic switching of regulation system, can also remotely manual control, with no way limit capacity, when power off, electric adjusting valve keep the position when power off, then pull shot round and operate manually
