Description

Purpose

This product is used in the electric-hydraulic proportional closed loop control system, together with proportional control amplifier. Gauge pin of differential inductance displacement sensor connects directly with armature to realize the direct inspection to valve spool, and then gets the accurate position of valve spool. This series of production have mass to use in proportional flux valve and proportional directional valve of REXROTH.

Operating Notice

The sensor and the stroke of the solenoid are OK when it finished, please don't adjust by yourself until you have any special requirements.
The socket of solenoids meet with ISO4400 standard.
Here is a protector of over-current between electrical control system and solenoid, in order to prevent the solenoid and the electrical component from burning in improper conditions.
The working medium of hydraulic system is mineral oil, phosphoric acid oil.
Make the vent hole above when installing, make sure the air exhausted from solenoid when you use it.
The solenoid fit for continuous duty.
Please note the current specification.
