This series of products are suitable for the control circuit of the winch system of all engineering machines to effectively control the start and shutdown of the brake. The optimized duplex series of products with higher integration degree and minimum materials can realize all functions of the hydraulic control valve of a winch brake, reducing pipeline, saving space and decreasing cost.

Basic parameters:
1. Rated working pressure: PH=25MPa;
2. Flow: 12L/min;
3. Opening pressure of hydraulically-controlled directional valve: 12~18bar.
