Gilmore Mark IV Shuttle Valve
Establishing a new benchmark for reliability and serviceability in drilling control systems where redundant hydraulic pressure supplies are required.
The Mark IV Shuttle Valve design improves upon the Mark III, adding better performance and modularity. The increase in cycle life of the valve was proven through extreme qualification testing to meet the demand of 5 year service life under normal operating conditions. This valve is best specified for new build equipment and system upgrades where you want to have the most reliable and serviceable shuttle valve in the market.
Significant engineering enhancements
• Improved seat geometry to eliminate shuttle metal to metal coining (mating) requirement
• Fully serviceable shuttles and seats
• Pressure biased adapters have increased flow capacity and improved guidance
Gilmore Mark IV Shuttle Valve
Stack flow capacity is increased by approximately 50% in both shuttle positions
Subsea
Improved seat geometry eliminates coining and minimizes leakage
Symmetic body porting, dual high drag o-rings, and hydraulic damping features ensure stable shuttle positioning in any flow condition
Benefits
