PRODUCT DESCRIPTION
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.
