英文介绍 (Product Description)
The 34S※-B20H-W manual directional control valve is designed for hydraulic systems requiring reliable flow path switching. Featuring lever-operated mechanism, it provides precise control of fluid direction in applications such as construction machinery, mining equipment, and industrial automation. The valve offers three-position/four-way or two-position/four-way configurations with optional spring return or detent versions (e.g., 34SM-B20H-W for detent type, 34SM-L10H-T for spring return).
Constructed with hardened alloy steel components and precision-ground spools, it ensures durability under pressures up to 31.5MPa. Standard mounting interfaces include ISO 4401 pattern with M14/M12 fasteners, compatible with most hydraulic power units. The compact design (92×77×130mm for Shanghai-type) simplifies installation while maintaining high flow capacity.
Typical applications involve directional control of hydraulic cylinders, motor speed regulation, and pressure circuit selection. The ergonomic handle reduces operator effort, and the modular design allows customization of port configurations (e.g., 7/8-14UNF ports). Optional middle position functions (open center, closed center, float) provide flexibility for diverse system requirements. 51125
This product line complies with general industrial performance expectations, offering consistent operation across temperature ranges of -20°C to +80°C. The corrosion-resistant surface treatment and nitrile sealing elements ensure reliable service life in typical hydraulic oil environments. Customers may select from multiple actuator options including extended levers or rotary knobs for specialized applications. 132729
