TS12-26

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

Overview

Description

The TS12-26X is a screw-in, cartridge style, pilot-operated, spool-type, relief valve which CAN be infinitely adjusted across a prescribed range using a variable electric current. The regulated pressure is proportional to the input electrical current

Operation

The TS12-26X blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to open the pilot section by offsetting the electrically induced solenoid force. With no current applied, the valve will relieve at approximately 100 psi [6,9]

Features

  • 12 and 24 volt coils standard.
  • Optional waterproof E-Coils rated up to IP69K.
  • Industry common cavity.
  • Optional manual override.
