TS98-30 Proportional Electric Reducing/Relieving
2.882.1
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type reducing/relieving 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 control device in demanding applications.
OPERATION
Without applied current, the TS98-30 allows bidirectional fl ow from ➂ to ➃ while
blocking
➁. When the coil is energized, ➂ is connected to ➁, and pressure at ➂ is
controlled proportional to the amount of current applied to the coil. If pressure at
➂
exceeds the setting induced by the coil, pressure is relieved to
➃.
Back pressure on port
➃ becomes additive to the pressure setting at a 1:1 ratio.
Note: This product may be customized for special OEM performance characteristics.
Consult factory.
FEATURES
• 12 and 24 volt coils standard.
• Optional waterproofed E-Coils rated up to IP69K.
RATINGS
Maximum Inlet Pressure at Port ➁: 24 bar (350 psi)
Maximum Control Current: 0.70 amps for 12 VDC coil; 0.35 amps for 24 VDC coil
Deadband: 0.150 amps @ 12 VDC; 0.075 amps @ 24 VDC
Hysteresis: 3.0% PWM
Reducing/Relieving Pressure Range from Zero to Maximum Control Current:
0–20.7 bar (0–300 psi)
Rated Flow: 30 lpm (8 gpm) at 45 psid port
➂ to ➃ with coil de-energized
Maximum Pilot Flow: 0.4 lpm (0.12 gpm)
Flow Path: Free Flow:
➂ to ➃ bidirectional coil de-energized; Reduced: ➁ to ➂ coil
energized; Relieving:
➂ to ➃ coil energized; Port ➀ is not plumbed externally
Temperature: -30 to 175°C (-20 to 350°F), with standard Fluorocarbon 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: VC98-3; See page 9.110.1; Cavity Tool: CT98-3XX; See page 8.600.1
Seal Kit: SK90-3V; See page 8.650.1
Coil Nut: Part No. 7004410;
For E-coils manufactured prior to 1-1-04, see page 3.400.1 for coil nut info.
