TS58-20 Valve

SYMBOL:
TS58-20 Valve symbol
DESCRIPTION
A screw-in, cartridge-style, direct acting, poppet-type hydraulic relief valve, which
can be infinitely 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 up to 345 bar (5000 psi).

OPERATION
The TS58-20 blocks flow from 1 to 2 until sufficient pressure is present at 1 to
offset the electrically induced solenoid force. With no current applied to the
solenoid, the valve will free flow from 1 to 2.
Note: Back pressure on port 2 becomes additive to the pressure setting at a 1:1 ratio.

FEATURES
• 12 and 24 volt coils standard.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.

RATINGS
Max. Operating Pressure: 428 bar (6200 psi) at port 1; 69 bar (1000 psi) at port 2
Proof Pressure: 448 bar (6500 psi) at port 1; 103 bar (500 psi) at port 2
Burst Pressure: 945 bar (13700 psi)
Flow Rating: 6.8 lpm (1.8 gpm) ΔP 5.5 to 8.3 bar (80 to 120 psi) Cartridge only;
   port 1 to port 2 with coil energized.
Adjustable Pressure Range from Zero to Maximum Control Current: 0 to 345 bar (0 to 5000 psi).
   Maximum pressure factory adjustable between 275.8 bar (4000 psi) and 345 bar (5000 psi) in
   6.9 bar (100 psi) increments.

Response Time: While current step from 0 to maximum - 0.045 sec. While current step
   from maximum to 0 - 0.008 sec.
Hysteresis: 3.5% maximum at 200 Hz dither or PWM.
Leakage: 0.275 cu. in./min (4.5 ml/min.) at 80% of maximum setting
Temperature: with standard polyurethane seals: -54 to 107° C (-65 to 225° F).
   Other seal options available; consult factory
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: 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; See page 9.020.1
Cavity: VC08-2; See page 9.108.1_2w
Cavity Tool: CT08-2xx; See page 8.600.1
Seal Kit: SK08-2x-B; See page 8.650.1
Coil Nut: Part No. 4540560
