Raymarine DBL Pilot Check Valv Product Description
Enhance Your Boat's Hydraulic Steering with the Raymarine Double Pilot Check Valve
Navigating open waters demands precision and reliability from every component in your marine setup. The Raymarine double pilot check valve steps in as a crucial safeguard for hydraulic autopilot systems, ensuring smooth operation and preventing unwanted pressure drops. Designed for boaters who prioritize performance, this valve maintains hydraulic lock in dual-pilot configurations, keeping your vessel on course even during system transitions or power fluctuations.
Unlike basic check valves, the double pilot design handles the complexities of multi-station autopilots, where two steering stations need seamless handover. It locks the hydraulic cylinder in place when the autopilot disengages, eliminating drift and enhancing safety on long passages or in rough seas. Boaters upgrading from older systems or troubleshooting intermittent steering issues often find this valve transforms their experience, restoring confidence in automated navigation.
Why Choose the Raymarine Double Pilot Check Valve for Your Vessel
- Superior Pressure Holding: Locks hydraulic pressure bidirectionally, preventing cylinder drift in both port and starboard directions—ideal for sailboats and powerboats with demanding steering loads.
- Seamless Dual-Station Compatibility: Perfect for setups with flybridge and helm stations, allowing pilots to switch without losing steering control.
- Durable Marine Construction: Built to withstand corrosive saltwater environments, vibrations, and high-pressure cycles, extending the life of your autopilot pump and ram.
- Easy Integration: Fits standard Raymarine hydraulic lines, minimizing downtime during installation and reducing the risk of leaks or air ingress.
- Improved Autopilot Efficiency: Reduces wear on pumps by maintaining system integrity, potentially lowering long-term maintenance costs.
Real-world feedback from offshore sailors highlights how this valve eliminates subtle helm feedback issues, providing a crisper, more responsive feel during autopilot engagement. Whether you're crossing oceans or weekend cruising, it delivers the reliability Raymarine is known for.
Installation and Maintenance Tips for Optimal Performance
Integrating the double pilot check valve into your hydraulic system is straightforward for those familiar with marine plumbing. Start by depressurizing the system, then locate the existing check valve inline between the autopilot pump and steering cylinder. Swap it out, ensuring proper orientation—pilot ports face the pump side for correct signal response.
- Flush lines to remove old fluid and debris.
- Secure fittings with marine-grade thread sealant.
- Bleed the system thoroughly to eliminate air pockets.
- Test under load in calm conditions before heading offshore.
For maintenance, inspect annually for corrosion or soft seals. A simple pressure test can reveal issues early. Pairing it with clean hydraulic fluid and routine filter changes keeps your setup running like new, avoiding costly pump failures.
Pro tip: In variable sea states, monitor for unusual pump cycling, which could signal valve fatigue—addressing it promptly prevents cascading problems in your steering array.
Compatibility and Common Troubleshooting
This valve shines in Raymarine Type 1 and Type 2 hydraulic autopilots, supporting pumps like the Chiropilot or Evolution series. It's a go-to replacement for aging systems on vessels from 30-50 feet, where dual-rudder or balanced-spade setups benefit most.
Troubleshooting steering wander? Check valve function first—symptoms like slow response or drift post-autopilot often trace back here. Swapping in a fresh unit resolves 80% of these cases, per marine tech forums and service logs.
Frequently Asked Questions
What does a double pilot check valve do in a hydraulic autopilot?
It maintains hydraulic pressure in the steering cylinder when the autopilot disengages or switches stations, preventing rudder drift and ensuring stable steering in dual-pilot setups.
Is the Raymarine double pilot check valve suitable for sailboats?
Yes, it's ideal for sailboats with hydraulic steering rams, handling the high loads from windvanes or tillers in Type 1 or 2 systems.
How do I know if my check valve needs replacing?
Look for symptoms like autopilot-induced helm drift, pump overheating, or fluid leaks. A pressure drop test confirms failure.
What's the difference between a single and double pilot check valve?
A single valve suits basic systems, while double pilot handles bidirectional control for multi-station or reversible rams, offering better lock in complex setups.
Can I install this valve myself?
Experienced DIY boaters can, with basic tools and hydraulic knowledge. Depressurize first, follow flow direction, and bleed air afterward.
Does it work with non-Raymarine pumps?
It integrates with compatible hydraulic pumps sharing Raymarine line specs, but verify pressure ratings and port sizes for best results.
How often should I service the check valve?
Inspect yearly, or more in harsh saltwater conditions. Replace every 5-7 years or at first sign of wear.
