Hebei DENENG Trade Co., Ltd

Hydraulic Motor Spool Valve Motor 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.

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.
