E-TS38-20 PRESSURE RELIEVING PROPORTIONAL VALVE
SYMBOL
OPERATION
The E-TS38-20 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to offset the electrically induced solenoid force. With no current applied, the valve will free flow from port 1 to port 2.
Note: The back pressure of port 2 will be 1:1 superimposed on the set pressure
SPECIFICATIONS:
Operating Pressure: 241 bar (3500 psi)
Flow rating: 11.4 lpm/3 gmp
Pressure drop:
20 bar (290 psi) Note: Cartridge only (A)
10 bar (150 psi) Note: Cartridge only (B)
5.5 bar (80 psi) Note: Cartridge only (C)
Hysteresis of 250Hz Flutter: 3.3% (Max.7% no flutter)
Flutter Frequency: 150 Hz or higher
Channel: Free flow 1 to 2, coil de-energized; Relieving: flow 1 to 2, coil energized.
Step response: T(open)﹤50ms; T(close)﹤7ms;
Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties
Fluid viscosity range: 7.4 to 420 cSt (50 to 2000 ssu)
Temperature: - 40℃ ~ + 120℃ (Standard Buna N seals)
Cavity: 08-2
Maximum pilot flow rate: 0.76 lpm(0.2 gpm)
Installation: If possible, the valve should be installed below the oil tank level. This can maintain the amount of oil in the armature, thereby avoiding instability caused by residual bubbles. If this installation cannot be achieved, installing the valve horizontally will achieve the best effect.
ELECTRICAL PARAMETERS:
Maximum control current: 12 VDC Coil 1.10 A; 24VDC Coil 0.55 A
Control the operating relieving pressure range when the current changes from zero to maximum:
A: 0-207 bar (0-3000 psi);
B: 0-138 bar (0-2000 psi);
C: 0-69 bar (0-1000 psi);
