Product Overview
The MARINEVALVE DG17S4-016C-JA-25-S1 is a lever-operated directional control valve engineered for precise flow routing in demanding hydraulic circuits. As a member of the DG17 series, this valve utilizes a manually actuated spool mechanism to direct pressurized fluid between ports, enabling controlled extension, retraction, and holding of hydraulic actuators. The “JA” designation indicates a spring-centered spool configuration, ensuring automatic return to the neutral position when the lever is released, which is critical for fail-safe operation in marine and industrial systems. With a nominal size of 16 (NG16 / CETOP 7 interface), this valve supports substantial flow rates while maintaining low pressure drop, making it suitable for high-capacity circuits where reliable directional control is paramount.

Engineering Features & Advantages
- Precision Spool Metering: The hardened, precision-ground spool and sleeve assembly ensures minimal internal leakage and accurate flow control, enabling smooth actuator response and precise positioning in critical marine and industrial applications.
- Spring-Centered Fail-Safe Operation: The JA spring return mechanism automatically returns the spool to the neutral (center) position upon lever release, preventing unintended actuator movement and enhancing operational safety in unattended or emergency conditions.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Precision-manufactured to original MARINEVALVE specifications for direct replacement, minimising downtime and eliminating fitment issues.
Typical Industrial Applications
The “JA” designation indicates a spring-centered spool configuration, ensuring automatic return to the neutral position when the lever is released, which is critical for fail-safe operation in marine and industrial systems.
