Ball valve 6DB series

leverdouble block-and-bleedbleed

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 • - Research Systems
