High efficiency, stable rotation under high pressure. Special pressure control mechanism and force balance. CAM ring of three-way support, greatly increased rotation and performance under high pressure, also performed well and stably under 140BSR.

No vibration, no noise, several methods of sound insulation and vibration control are adopted, especially can improve the CAM ring rotational vibration without noise.

Sensitive and high precision. New CAM ring control mechanism without displacement, thus improve the response sensitivity. The precision remains the same during start, stop or load change. It can keep smooth flow under high pressure with new pressure balance control mechanism.

Adopt new mechanism to reduce energy loss, especially under high pressure no wheel out state. Easy to repair.

The pressure and flow mechanisms are put on the same side, easy to maintain and adjust.
