TS90-G34 Valve

SYMBOL:
TS90-G34 Valve symbol
DESCRIPTION
A pilot-operated, spool-type, proportional pressure reducing/relieving valve. It is athird-generation
HydraForce drop-in, flange-mounted, cartridge-type valve. The coilis an integral part of the valve
and is not serviceable. The regulated pressure is proportional 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 energized, 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.

RECOMMENDED ELECTRONIC CONTROLLERS
The EVDR Series controllers are recommended for use with most HydraForce
proportional valves. These newer electronic controllers are versatile, reliable, and
easily configured and customized for a wide range of applications.
See the EVDR Product Selection Guide.
