Ball Valve Double Block & Bleed (1034 bar) 10DB Series

Parker Autoclave Engineers Double Block & Bleed valve is a two-stem ball valve with needle style vent valve providing economical and reliable isolation in critical areas superior in comparison to a standard, single valve. This valve is designed for use where critical isolation is needed to ensure that leakage does not occur. Our 3/8" and 5/8" Double Block & Bleed valves are designed to save space and weight while capable of pressures to 15,000 psi (1034 bar). These ball valves can also be modified to incorporate the use of special materials, optional seals with and capability for high-temperature applications to 500°F (260°C).
