TS58-21F Valve
U.S. Patent 6,267,350

TS58-21F Valve symbol
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 inversely proportional to DC current input.

The TS58-21F blocks flow from 1 to 2 until sufficient pressure is present at 1 to open
the valve by overcoming the preset spring force. With no current applied, the valve will
relieve at ±50 psi of the spring maximum. Applying current to the coil reduces the induced
spring force thereby reducing the valve setting.

• 12 and 24 volt coils standard.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
• Hardened parts for long life.

Max. Operating Pressure: 393 bar (5700 psi)
Pressure Setting Range: From 4000 psi (276 bar) to 5000 psi (345 bar)
Electrical Parameters:

Relief Pressure Range from zero to max. control current: 344.7–6.9 bar (5000–100 psi)
Rated Flow: 1.9 lpm (0.5 gpm); ΔP = 6.9 to 9 bar (100 to 130 psi),
   cartridge only, 1 to 2 coil energized
Flow Path: Free Flow: 1 to 2 coil energized; Relieving: 1 to 2 coil de-energized
Temperature: -40° to 100°C (-40° to 212°F) with Buna seals;
   -26° to 204°C (-15° to 400°F) with fluorocarbon seals;
   -54° to 104°C (-65° to 225°F) with polyurethane seals
Hysteresis at 200 Hz PWM: 5%
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. 4540550
