NPI45B30 581CC OVAL 8L/min 13.7MPa Rc3/8 Valve Position Indicator

Description

OVAL NPI45B30 581CC is a compact valve position indicator featuring an 8 L/min maximum flow capacity and a 13.7 MPa maximum operating pressure. The device utilizes a positive displacement mechanism with dual non-circular rotors to measure the volume of hydraulic oil delivered to valve actuators. Constructed with an FC250 cast iron body and a magnetic coupling, it integrates a 581CC transmitter assembly providing both potentiometer and microswitch outputs. The unit includes a slip friction clutch and a mechanical pointer for local status monitoring.
