BM4 is a large spool valve, high pressure motor, with radial ball-bearings design, and can bear greater load.

 

Characteristic features:

It adapts the gerolor design, which has a higher distribution accuracy and mechanical efficiency.

The motor can be used in high pressure and high torque.

Double taper roller bearings permit high radial loads.

Credible design for shaft seal , which can bear high pressure.

A variety of connection types of flange, output shaft and oil port.

Note: 

1. Intermittent means the entrance of maximum pressure; continuous working pressure means the differential pressure.

2. Motor should not work under the highest pressure and the maximum speed.

3. The running time should not exceed 10% under intermittent working conditions.

4. The Maximum working temperature is 80℃.

5. The maximum allowable back pressure is 10Mpa, but the recommended back pressure should not exceed 5MP, a leaking pipes is needed when exceeding.

6. One hour running time under 40% of maximum working pressure is recommended before full capacity working.

7. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanliness ISO 18/13.
