6DB系列高壓雙斷流球閥，可工作到15000磅/平方英寸（1034巴），并提供各種連接。標(biāo)準(zhǔn)球閥采用316不銹鋼材質(zhì)，可提供特殊材料。Parker高壓滅菌器的6DB系列雙斷流和泄放球閥設(shè)計為在各種端部連接中提供高性能的優(yōu)質(zhì)閥門。一些更獨(dú)特的設(shè)計創(chuàng)新包括一個整體式的耳軸安裝式閥球和閥桿，消除了“閥桿道岔”的可能性，與其他為類似用途設(shè)計的閥門相同。此外，這些特殊球閥具有可重新扭轉(zhuǎn)的閥座壓蓋，可延長閥座壽命，以及低摩擦閥桿密封，可降低驅(qū)動扭矩并提高循環(huán)壽命。Parker Autoclave 6DB Series high pressure double block and bleed ball valve is capable of operating to15,000 psi (1034 bar) and is available various connections. Standard ball valves are furnished in 316 SS with specials materials available.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
