弁開度指示計 / NPI45形_容積流量計

Connected in series with the hydraulic circuit of a hydraulic drive system, the valve position indicator shows from time to time the valve position or the actuator position of similar equipment by measuring the quantity of oil delivered. The NPI series in particular is specifically designed small in size and lightweight with minimum space requirements. These desirable features make this series ideal for central control of multiple loading/off-loading valves used in oil tankers.

FEATURES

1. Can mount microswitches, potentiometer, or other devices to transmit remote signals: Ideal tool for playing the role of central control.
2. Uses an Oval PD meter for measuring the amount of operating oil displaced: A high accuracy, simple design, sturdy, and compact.
3. The pointer comes into contact with the stopper at 97 to 100% of valve actuator capacity and the remaining 0 to 3% capacity is absorbed by the slip friction clutch. Therefore, the pointer position is automatically corrected each time the valve is opened or shut.
