They accelerate the development cycle for innovative machinery.

    Auxiliary Function Control with Manually Operated Directional Valves in Larger Systems

    Managing Secondary System Operations

    Larger hydraulic systems often require control over secondary operations. Manually operated directional valves effectively manage these functions. They direct fluid flow to various auxiliary components. For example, a SpoolValve can connect multiple flow sources to different users. This allows operators to direct fluid for tasks like operating a clamp or rotating an attachment. A StopValve acts as a simple on/off switch. It controls the flow to specific parts of the system. This provides precise control over non-primary functions. These valves ensure efficient management of all system operations.

    Cost-Effective Control Solutions

    Manually operated directional valves offer a cost-effective solution for auxiliary control. They eliminate the need for complex electronic controls or expensive automated systems.

They add versatility to the machine. This integration enhances the machine’s overall utility. It does so without complicating the main operational controls.

    Understanding DWMG Series Manually Operated Directional Valves

    Direct-Acting Mechanism

    The DWMG series valves employ a direct-acting mechanism. This design means the operator’s physical input directly moves the spool inside the valve. This direct action ensures immediate and precise control over fluid flow. It eliminates the need for pilot pressure or complex linkages. The direct-acting nature contributes to the valve’s reliability and responsiveness. Operators experience a direct connection to the hydraulic system. This mechanism simplifies the valve’s internal structure.

    Detent and Spring Return Options

    DWMG series valves offer two primary control options: detent and spring return. Detent valves hold their position once an operator selects it. This feature is useful for applications requiring a constant flow direction without continuous operator engagement. Spring return valves, conversely, return to a neutral or home position when the operator releases the lever. This option provides a safety feature, ensuring the system reverts to a default state. Engineers choose between these options based on specific application requirements and safety protocols.

    Available Valve Sizes (DWMG10, DWMG16, DWMG22, DWMG25, DWMG32)
