Custom double-block-and-bleed valve

A custom compact double block and bleed valve is helping to reduce the size and weight of a groundbreaking skid produced for the Chevron Tahiti platform in the Gulf of Mexico. Parker Hannifin’s integrated valve provides a 15,000-psi rated double block and bleed function. Parker Hannifin suggested an uprated version of its single-piece 10,000-psi double block and bleed manifold, fitted with the company's unique 15,000-psi rated MPI compression tube fittings. The resulting manifold is estimated to have reduced the mounting space and weight budgets by around 50 percent, and replaces around nine individual components (three valves and six anti-vibration glands) – greatly reducing potential leak paths.
