The high working pressure is 35Mpa (5000psi) and the maximum oil flow rate is 160 liters/minute (42 gallons/minute).
The oil-immersed movable iron core makes the solenoid valve stable and quiet under high pressure and high frequency operation, and can increase the valve life.
The back pressure of the oil return port can be as high as 21Mpa (3040psi), please refer to the maximum allowable pressure of each valve shaft type in the specification table.
RAC AC and DC coils can reduce voltage surge, provide quieter operation and increase relay contact life.
The double return oil flow passage design can greatly reduce the pressure drop of the return line and reduce the temperature rise.
Junction box∕Plug coil
Provide a standard large electrical box with indicator light, terminal remover and ground terminal.
Simple design, easy to install and disassemble.
The coil is easy to replace, does not interfere with wiring, and there is no risk of oil leakage.
Outgoing wire coil
Wire coils commonly used in the market. (Double outlet type)
It can also provide single-outlet type single-pin type DC coil. (Vehicle construction machinery is more commonly used)
DIN plug type coil
According to the standard design of DIN 43 650 and ISO 4400 three-pin standard connectors.
The AC coil is suitable for 50/60Hz current, and there is no need to replace the coil and rewire when changing the frequency.
The DC coil has no polarity.
DIN plug connector

Compliant with DIN43 650 and ISO 4400 standard three-pin type standard connector. Provide a standard AC coil with a light indicator connector, and you can also purchase a DC coil with a light indicator.
AC solenoid
Using general 50-60Hz electromagnetic coil, there is no need to replace the coil and rewire when changing the frequency.
RAC AC/DC solenoid valve (electrical buffer type)
Provide an optional RAC AC/DC rectifier coil to reduce the voltage surge when AC is converted to DC, make the operation quieter and extend the life of the relay contact. When using a rectifier coil, long-term use can greatly reduce the heat generated by the coil.
Hydraulic buffer solenoid valve
The solenoid valve of optional item "S" can also be provided to slow down the changing speed of the valve shaft. When the electromagnet core moves in the large core tube, it will increase the conversion time up to four times (depending on the temperature).
Note: RAC AC/DC/DC DC solenoid directional valve can be provided; the solenoid valve will not be able to perform low-impact (buffer) operation before the hydraulic oil is filled with the oil return line... After a few cycles, the oil return port is It can be automatically filled with hydraulic oil and works normally.
Other considerations
The pressure rating of the oil return port may be lowered...Please check the maximum allowable pressure (including sudden pressure increase) of each valve shaft type. The coil is not installed in the movable iron core, please do not send power to the AC solenoid coil to avoid burnt. When designing differential circuits or other special circuits, when using 2B8, 2B8L, 2D8 valve shafts, the T-hole oil return port must not be plugged, and the oil return groove must be piped to ensure the normal operation of the solenoid valve.
Other styles
The company has a variety of solenoids with different diameters from 02/NG06 to 03/NG10, AC AC or DC DC solenoid coils, junction box type or DIN plug type, different valve shaft types, RAC AC/DC type or hydraulic buffer type, etc. To valve for your choice.
Recommended fluid type
Petroleum-based mineral oil (conforms to ISO VG32 & 46 specifications).
Phosphate ∕ polyol grease hydraulic oil.
Water-glycol hydraulic oil.
Liquid temperature range
Suggested value: +5℃ to +60℃ (41℉-140℉).
Fluid viscosity range
Suggested value: 15-310 cst (80-1400 SSU)
Pollution control
The hydraulic oil pollution should be maintained above NAS 1638-12 level, and the oil filter of 25 μm or better should be used, otherwise the electromagnetic directional valve will be easily damaged or shorten the service life.
