PRESSURE RELIEVING PROPORTIONAL VALVE

Expand All|Collapse All

Overview

Description

TS38-20 is a direct-acting, single stage, poppet-type, proportional, pressure relieving valve. The regulated pressure is proportional to the input electrical current.

Operation

The TS38-20 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to offset the electrically induced solenoid force. With no current applied, the valve will free flow from port 1 to port 2.

Features

  • Industry common cavity.
  • Manual override option.
