TS90-G34 Proportional Pressure Reducing/Relieving
2.888.1
ELECTRO-PROPORTIONAL VALVES—PRESSURE CONTROLS
DESCRIPTION
A pilot-operated, spool-type, proportional pressure reducing/relieving valve. It is a
third-generation HydraForce drop-in, flange-mounted, cartridge-type valve. The coil is
an integral part of the valve and is not serviceable. The regulated pressure is propor-
tional to the input electrical current in the pressure ranges shown.
OPERATION
Without applied current, the TS90-G34 allows free flow from 3 to 4. When the coil is
energized, in reducing mode, flow is allowed from port 2 to 3. When the coil is ener-
gized, in relieving mode, flow is allowed from port 3 to 4.
FEATURES
• Economical drop-in style.
• Optional 233 micron mesh screen.
• Optional lock-down flange.
• Choice of several regulated pressure ratings.
• Several push-on termination options.
• Integral waterproof coil standard, IP69K, 1000-hour salt spray per ASTM B117.
