派克 Autoclave 20,000 PSI 2B 系列兩通球閥
Parker Autoclave 2 Way 2B Series 20,000 PSI Ball Valve 二通球閥

派克 Autoclave 的 2B 系列球閥旨在提供卓越的質(zhì)量，以在各種閥門樣式、尺寸和過(guò)程連接中實(shí)現(xiàn)最大性能。這些球閥具有一體式耳軸安裝球和閥桿，可消除兩件式設(shè)計(jì)常見(jiàn)的剪切故障。閥座壓蓋可重新擰緊以延長(zhǎng)閥座壽命，低摩擦壓力輔助石墨填充 PTFE 閥桿密封可降低驅(qū)動(dòng)扭矩并增加循環(huán)壽命。這些閥門具有全端口流路，可最大限度地減少壓降，并配有 PEEK 閥座，以確保出色的耐化學(xué)性、耐熱性和耐磨性。

作為標(biāo)準(zhǔn)配置，這些高壓球閥由冷加工 316 不銹鋼制成，能夠在高達(dá) 20,000 PSI (1,379 bar) 的壓力下運(yùn)行。接液部件也有其他材料。閥門配有 Viton O 型圈，額定工作溫度范圍為 -17.8 至 204°C（0 至 400°F）。可選擇使用其他 O 形圈材料，以將上限擴(kuò)展至 260?C (500?F)。

Parker Autoclave’s 2B Series Ball Valves are quarter turn, manual 2 way valves. These ball valves operate up to 20,000 psi (1,379 bar) with a variety of end connections. These valves also feature a trunnion mounted stem.

Parker Autoclave's 2B Series ball valves have been designed to provide superior quality for maximum performance within a variety of valve styles, sizes, and process connections. These ball valves feature an integral one-piece trunnion mounted ball and stem that eliminates the shear failure common to two-piece designs. The seat glands are re-torqueable for longer seat life, and the low friction pressure-assisted graphite filled PTFE stem seal reduces actuation torque and increases cycle life. The valves have a full port flow path that minimizes pressure drop, and are fitted with PEEK seats to ensure excellent chemical, heat and wear resistance.

As standard, these high pressure ball valves are manufactured from cold worked 316 stainless steel and are capable of operating at up to 20,000 PSI (1,379 bar). The wetted parts are also available in other materials. The valves are fitted with Viton O-rings, rated for operation over a temperature range of -17.8 to 204?C (0 to 400?F). Other O-ring materials are optionally available to extend the upper limit to 260?C (500?F).
