Parker Autoclave 4B 系列 4 通球閥
Parker Autoclave's 4B Series ball valves
派克 Autoclave 的 4B 系列球閥旨在提供卓越的質(zhì)量，以在各種閥門類型、尺寸和過程連接中實現(xiàn)最佳性能。一些更獨特的設(shè)計創(chuàng)新包括一體式耳軸安裝式球和閥桿，消除
了兩件式設(shè)計中常見的剪切失效，可重新擰緊的閥座密封套，延長閥座壽命，以及低摩擦閥桿密封，減少驅(qū)動扭矩并提高循環(huán)壽命。這些球閥還可以進行修改，以結(jié)合使用特殊材料、高溫應(yīng)用密封件、海底模型和閥門執(zhí)行器。當(dāng)涉及到高壓應(yīng)用時，這些球閥
與相關(guān)的高壓組件一起提供高壓市場所需的關(guān)鍵性能。

Parker Autoclave's 4B Series ball valves have been designed to provide superior quality for maximum performance within a variety of valve styles, sizes, and process connections. Some of the more unique design innovations include an integral one-piece trunnion mounted style ball and stem that eliminates
the shear failure common in two piece designs, re-torqueable seat glands that result in longer seat life, and a low friction stem seal that reduces actuation torque and enhances cycle life. These ball valves can also be modified to incorporate the use of special materials, seals for high temperature applications, subsea models, and valve actuators. When it comes to high-pressure applications, these ball valves
with associated high-pressure components, provide the critical performance demanded by the high pressure market.
Markets:
- Oil and Gas
- Petrochemical
- Research
- Chemical
- Power
Features/Benefits:
- One-piece, trunnion mounted style, stem design eliminates shear failure found in two piece designs and reduces the effects of side loading.
- Re-torqueable seat glands for longer seat life.
- Carbon filled PEEK seats offer excellent resistance to chemicals, heat, and wear/abrasion.
- 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 crossover, and the half turn four way switching models available.
