DESCRIPTION

A screw-in, cartridge-style, pilot-operated, spool-type hydraulic relief valve, which can

be infinitely adjusted across a prescribed range using a variable electric input.

Pressure output is inversely proportional to DC current input. This valve is intended

for use as a pressure-limiting device in demanding applications.

OPERATION

The TS10-27 blocks flow from 1 to 2 until sufficient pressure is present at 1 to open

the valve by overcoming the preset induced spring force. With no current applied,

the valve will relieve at ±50 psi of the range maximum. Applying current to the coil

decreases the induced spring force, thereby reducing the valve setting.

Note: This valve is ideal for hydraulic fan drive applications. Consult factory for

electronic controllers specifically designed for fan drive applications.

FEATURES

• 12 and 24 volt coils standard.

• Industry common cavity.

• Adjustable or fixed relief pressure settings.

• Higher pressure 330.9 bar (4800 psi) factory-set model F available.

Operating Fluid Temperature: -40 to 100°C (-40 to 212°F) with standard Buna N

seals; -26 to 204°C (-15 to 400°F) with fluorocarbon seals; -54 to 107°C (-65 to

225°F) with polyurethane seals.

Filtration: See page 9.010.1

Fluids: Mineral-based or synthetics with lubricating properties at viscosities of

7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1

Installation Recommendation: When possible, the valve should be mounted below

the reservoir oil level. This will maintain oil in the armature preventing trapped air

instability. If this is not feasible, mount the valve horizontally for best results.

Cavity: VC10-2; See page 9.110.1

Cavity Tool: CT10-2XX; See page 8.600.1

Seal Kit: SK10-2X-B; See page 8.650.1

Coil Nut: Part No. 4540550;

For E-coils manufactured prior to 1-1-04, see page 3.400.1 for coil nut info.
