MADE IN JAPAN

The Azbil VPP 03-1 (P-9B9DE-42-003) is a double action pneumatic valve positioner from the shipboard marine control system. It takes a pneumatic input signal of 0.2-1.0 kgf/cm2 and drives a double acting actuator from a 4.6-7.0 kgf/cm2 air supply, setting the valve opening that the control signal calls for. This unit is tagged for the boiler steam dump control valves CV-011 and CV-021, positioning the dump valves on the boiler steam line. It is offered in used condition and was made in Japan.
