Technical Parameters
1. Inlet pressure: rated pressure 20bar;
2. T port back pressure: maximum 3bar;
3. Minimum flow: not less than 5L/min, maximum flow 20L/min;
4. Hydraulic oil temperature range: -20℃~+90℃;
5. Hydraulic oil: suitable for nitrile rubber seals, meets DIN51524 mineral oil (HL, HLP)
6. Viscosity range: 10mm²-380mm²;
7. Oil contamination level: maximum allowed is NAS 1638 level nine. Therefore, we recommend the minimum filtration ratio of the filter to be β10≥75
8. Maximum allowable operating torque of the handle: 6N.m during operation; 30N.m for special one-time requirements
9. JIS B 2351 G1/4 oil port: corresponding oil ports P, T, 1, 2, 3, 4
10. Red wire connects to 2, 4, corresponding to switch 2;
11. Yellow wire connects to 1, 3, corresponding to switch 1;
12. Electrical switch and wire current capacity 2A;
13. Voltage 24DC.
Features:
1. Suitable for fully hydraulic bulldozers;
2. Ports 1 and 3 control forward and backward, when operating either port 1 or 3 to the end,
the operating handle will lock and become immovable, locking force 1N.m-1.2N.m;
3. The handle is set with two quick closures, which can control the speed gear for forward and backward;
4. Ports 1 and 3 are locked for hydraulic locking, hydraulic locking is efficient, while not increasing the product size.
5. Ports 2 and 4 provide inverse proportional output, controlling steering and large steering.
