VP01 2VAA008172R01 VP01 Valve Positioner module
Product Description
The VP01 Valve Positioner module provides control of the flow of steam, gas, or water through a turbine by precisely regulating the position of the inlet valves. It is intended for modulation of hydraulic actuators via servo valves or I/H converters..
The VP01 performs closed loop control for servo valves utilizing single or redundant position feedback devices, or open loop control for current drive valves. It offers a response time from input to output under 1 millisecond and can generate servo output signals up to 500 milliamps per servo coil output. The feedback devices can be AC or DC LVDT’s and the control output can be Proportional-Integral or Proportional-Only.
