DESCRIPTION

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

be inﬁ nitely adjusted across a prescribed range using a variable electric input.

Pressure output is proportional to DC current input. This valve is intended for use as

a pressure limiting device in demanding applications.

OPERATION

The TS10-26 blocks ﬂ ow from ➀ to ➁ until sufﬁ cient pressure is present at ➀ to open

the pilot section by offsetting the electrically induced solenoid force. With no current

applied to the solenoid, the valve will relieve at approximately 100 psi.

The optional manual override allows the valve to be set when the electric supply is

lost. The manual setting is added to the electric setting. To prevent the system from

being over pressurized, the manual override should always be disengaged prior to

applying power to the coil.

FEATURES

• Optional Manual Override.

• Optional waterproof E-Coils rated up to IP69K.

• 12 and 24 volt coils standard.

• Industry common cavity.

RATINGS

Maximum Operating Pressure: 241 bar (3500 psi)

Maximum Control Current: 1.10 amps for 12 VDC coil; 0.55 amps for 24 VDC coil

Relief Pressure Range from Zero to Maximum Control Current:

A: 6.9–207 bar (100–3000 psi) C: 6.9–117 bar (100–1700 psi)

B: 6.9–159 bar (100–2300 psi)

Rated Flow: 94.6 lpm (25 gpm), ΔP=13.1 bar (190 psi), Cartridge only,

➀ to ➁ coil de-energized

Maximum Pilot Flow: 0.76 lpm (0.2 gpm)

Hysteresis: Less than 3%

Flow Path: Free Flow:

➀ to ➁ coil de-energized; Relieving: ➀ to ➁ coil energized

Temperature: -40 to 100°C (-40 to 212°F) with standard Buna N 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: SK10-2N-B; See page 8.650.1

Coil Nut: Part No. 4540560;

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

Before operating valve,

use the manual override

to manually set pressure

to 200 to 300 psi. Before

operating electrically,

back out manual override

(CCW using 3/16" hex key

wrench) until positive stop

is reached. Manual override

must be fully backed out

when operating electrically.
