English Version
The 4WMM16-50 Manual Directional Control Valve is a fluid control device specifically designed for hydraulic systems, featuring a classic spool structure controlled by manual lever operation. This product is widely applicable in hydraulic circuit control for construction machinery, agricultural equipment, and industrial automation systems, enabling precise switching of hydraulic circuits to manage the operation of actuators such as hydraulic cylinders and motors.
Manufactured with high-strength alloy casting, the valve body incorporates precision-machined 4-way/3-position structure that ensures smooth spool movement. The mating surfaces undergo specialized hardening treatment, supporting operational pressure range from 0.5 to 31.5 MPa. Multi-layer anti-corrosion coating on the exterior enables reliable performance within ambient temperatures of -20°C to +80°C. The ergonomic lever handle features clear position indicators, requiring ≤5N·m operating torque, with optional spring return or detent positioning modes.
Key product features include: 1) Modular design allowing flexible port configuration for system integration; 2) Precision clearance control (0.005-0.015mm) between spool and body minimizes internal leakage; 3) Serviceable construction with detachable components for field maintenance; 4) 60° cone-sealed ports compatible with standard hydraulic connections. Recommended for use with filtered hydraulic fluids (≤25μm filtration) including mineral-based oils and eco-friendly fluids like water-glycol mixtures.
This valve excels in scenarios requiring manual intervention, such as equipment commissioning tests, emergency manual override operations, or as backup control units in automated systems. The compact design (mounting interface compliant with ISO 4401) optimizes space utilization, with main dimensions measuring 152×85×68mm (L×W×H) and approximate weight of 1.8kg, facilitating installation in confined spaces. Dimensional standardization ensures compatibility with common hydraulic manifold configurations.
