PV76-30A

NORMALLY CLOSED PROPORTIONAL FLOW REGULATOR

Overview

Description

Pv76-30 is a solenoid operated, pressure compensated, spool type, normally closed proportional flow control valve

Operation

The valve CAN be used as priority type flow regulator with pressure compensated regulated and bypass flow. It CAN also be used as a restrictive type, 2-way, pressure compensated flow regulator when bypass line (port 2) is blocked. The regulated flow is proportional to electric current applied to the solenoid

Features

  • Excellent linearity and hysteresis characteristics.
  • Hardened spool and cage for long life.
  • Optional coil voltages and terminations.
  • Efficient wet-armature construction.
  • Manual Override option.
