Overview

Description

PV72-30 is a solenoid operated, pressure compensated, spool type, normally closed, proportional priority flow control valve.

Operation

The valve provides priority regulated flow at port 3 with pressure compensated regulated and bypass flow. The regulated flow is proportional to electric current applied to the solenoid.

Features

  • Choice of two regulated flow ranges
  • Excellent linearity and hysteresis characteristics.
  • Optional coil voltages and terminations.
  • Efficient wet-armature construction.
  • Cartridges are voltage-interchangeable.
  • Unitized, molded coil design.
  • Coil waterproofing standard.
  • Manual Override option.
