PRESSURE REDUCING/ RELIEVING PROPORTIONAL VALVE U.S. PATENT # 7,137,406

Overview

Description

This is a pilot operated spool type, proportional pressure reducing/relieving valve. It is intended for use in mineral based or synthetic (with lubricating properties) hydraulic fluids

Operation

The regulated pressure is proportional to the input electrical current in the pressure ranges shown below. Maximum operating pressure port 1 and port 2: 4000 psi [275,8 bar] maximum tank pressure port 3: 1000 psi [68,9 bar] (tank pressure is additive to regulated pressure

Features

  • 12 and 24 volt coils standard.
  • Standard waterproof coils or optional waterproof E-Coils.
