Parker Autoclave's 6DB Series double block and bleed ball valves have been designed to provide superior quality for maximum performance within a variety of end connections. Some of the more unique design innovations include an integral one-piece trunnion mounted style ball and stem that eliminates the possibility of "stem-turnout" common with other valves designed for similar service. In addition, these specialty ball valves have re-torqueable seat glands that result in longer seat life, and a low friction stem seal that reduces actuation torque and enhances cycle life.
Markets:
• Oil and Gas
• Petrochemical
• Research
• Chemical
• Power
Features/Benefits:
• One piece, trunnion mounted stem design eliminates shear failure and reduces the effects of side loading found in two piece designs.
• Re-torqueable seat glands for longer seat life.
• Carbon filled PEEK seats offer excellent resistance to chemicals, heat and wear/abrasion.
• Vee-stem vent valve.
• Full-port flow path minimizes pressure drop.
• 316 cold worked stainless steel construction.
• Low friction pressure assisted graphite filled PTFE stem seal increases cycle life and reduces operating torque.
• Quarter turn from open to close with positive stop.
• Viton o-rings for operation from 0°F (-17.8°C) to 400°F (204°C).
Applications:
• High Pressure Skid Panels
• Specialty High Pressure Gas Systems
