A screw-in, cartridge-style, single-stage, poppet-type pressure relieving 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.
Maximum Operating Pressure: 393 bar (5700 psi)
Relief Pressure Range from Zero to Maximum Control Current: 344.7–6.9 bar (5000–100 psi)
Hysteresis at 200 Hz PWM: 5%
Rated Flow: 1.9 lpm/0.5 gpm; P = 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 121°C (-40° to 250° F) with standard Buna N seals-35° to 204°C (-31° 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.
