G20/G25/G32/G40 Marine Manual Proportional Flow Composite Valve

The G20, G25, G32, and G40 Marine Manual Proportional Flow Composite Valves are advanced three-position, four-way directional valves designed for marine and hydraulic control systems. These valves are equipped with pressure compensation, flow proportional adjustment, and protection features, which ensure smooth and precise operation in various hydraulic applications. The valve’s operation is synchronized with the flow adjustment mechanism, enabling infinitely variable speed control and excellent shifting and speed regulation performance. Constructed from high-strength spheroidal graphite cast iron, these valves are known for their durability, ease of operation, and long service life. They are widely used in marine machinery and other mechanical hydraulic control systems.

Product Advantages

1. Pressure Compensation
   - The G-series valves include an integrated pressure compensation function, which ensures that flow remains constant, even as system pressure changes. This feature is crucial in maintaining stable operation across different load conditions, improving system efficiency and reliability.

2. Flow Proportional Adjustment
   - These valves offer precise flow control, allowing users to adjust the flow rate proportionally to the operator’s input. The synchronization between the valve handle and the flow adjustment mechanism ensures smooth and continuous flow regulation, contributing to consistent performance.

3. Protection Mechanisms
   - Built-in protective features safeguard the valve and hydraulic system from damage caused by unexpected pressure spikes or flow inconsistencies. These protective elements help prolong the valve’s lifespan and prevent costly downtime.

4. Ease of Operation
   - The manual control handle is ergonomically designed, offering users a straightforward and intuitive interface. With synchronized adjustments, operators can effortlessly control flow rates and switching functions without the need for complex training or excessive effort.

5. Durability and Longevity
   - Made from high-strength spheroidal graphite cast iron, the valve body is resistant to wear and tear. This material choice enhances the valve’s strength and durability, making it ideal for long-term use in challenging marine environments.
