1, High energy efficiency, reducing the use cost
Because the hydraulic spool body flow with special structural design, the internal impedance is small, can reduce the internal pressure loss, to improve energy efficiency.
2, Can withstand high pressure
The use of special materials and design, can work under the pressure of 250bar, increased the scope of application, when working at low pressure, the service life is longer.
3, Excellent waterproof and dustproof
Electric connection mode, there are two kinds of connection box and plug type connection seat, all have the indicator light. The electric connection box and the coil form all have strict waterproof property and dust resistance.
4, High quality
Test by automatic test equipment, to ensure high and stable quality.
5, Easy to install
The hydraulic back pressure valve body is fixed with external screw, which can be easily disassembled and assembled.The space of electrical wiring is large, easy to install wiring.
6, Reduce the oil temperature to improve life, save maintenance cost
Due to the small impedance, using pressure drop is reduced, hydraulic oil temperature is also reduced accordingly, hydraulic oil is not easy to deteriorate, prolonging the service life of hydraulic oil, reducing the replacement cost of the hydraulic oil, machine itself caused deformation of machining precision error to the base because of being affected by the heat.
7, Special coil, safe and durable
Fixed nut soleniod coil with special locking design, can prevent the soleniod coil off due to the resonance of machine. The solenoid coil with low impact voltage can ensure the security of computer system.
8, Excellent oil immersed type solenoid action design
The action of hydraulic spool dip in system has a moderating effect, even under high pressure and high frequency switching action, still can be smooth and silent. Oil immersed type spool core, completely eliminates the moving parts of the oil seal and slip between the push rod column friction and the resulting problem of oil leakage, and can increase the thrust of the sliding column.
