TS38-21

PRESSURE RELIEVING PROPORTIONAL VALVE U.S. PATENT # 6,267,350

Overview

Description

Description: TS38-21 is a direct-acting, spool-type, proportional, pressure relieving valve. The regulated pressure is inversely proportional to the input electrical current. Port 1 is protected by 150 mesh screen

Operation

The TS38-21 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to open the valve by overcoming the preset induced spring force. With no current applied, the valve will relieve range maximum. Applying current to the coil decreases the induced spring force, thereby reducing the valve setting

Features

  • 12 and 24 volt coils standard.
  • Optional waterproof E-Coils rated up to IP69K.
  • Industry common cavity.
  • Hardened parts for long life.
