ELECTRO-PROPORTIONAL VALVES—PRESSURE CONTROLS
TS58-20 Proportional Electric Relief Valve
DESCRIPTION
A screw-in, cartridge-style, direct acting, poppet-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 TS58-20 blocks fl ow from ➀ to ➁ until suffi cient pressure is present at ➀ to offset
the electrically induced solenoid force. With no current applied to the solenoid, the
valve will free fl ow from
➀ to ➁.
Note: Back pressure on port
➁ becomes additive to the pressure setting at a 1:1 ratio.
FEATURES
• 12 and 24 volt coils standard.
• Industry common cavity.
• Optional waterproof E-Coils rated up to IP69K.
RATINGS
Maximum Operating Pressure: 345 bar (5000 psi)
Maximum Tank Port Pressure: 69 bar (1000 psi)
Relief Pressure Range: Model Code 40: 0–276 bar (0–4000 psi);
Model Code 50: 0–345 bar (0–5000 psi)
Note: Minimum pressure setting is dependent on fl ow through the valve.
(See Pressure Drop Curve)
Flow: See Performance Charts
Flow Path: Free Flow:
➀ to ➁ coil de-energized; Relieving: ➀ to ➁ coil energized
Maximum Control Current: 1.10 amps for 12 VDC coil; 0.55 amps for 24 VDC coil
Control Signal: DC or PWM (Signifi cant improvements in valve performance occur
with superimposed dither, with either control method.)
Dither Frequency: 150 Hz or higher
Hysteresis with Dither 250 Hz: 3.3% (7% maximum without dither)
Step Response: T
ON
<50 ms; TOFF <7 ms
Operating Temperature: with standard Buna N seals: -40 to 120°C (-40 to 250°F)
with Fluorocarbon seals: -35 to 204°C (-31 to 400°F)
with Polyurethane seals: -54 to 107°C (-65 to 225°F)
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: VC08-2; See page 9.108.1; Cavity Tool: CT08-2XX; See page 8.600.1
Seal Kit: SK08-2X-B; See page 8.650.1
