派克 Autoclave 20,000 PSI 2B 系列两通球阀
Parker Autoclave 2 Way 2B Series 20,000 PSI Ball Valve 二通球阀

派克 Autoclave 的 2B 系列球阀旨在提供卓越的质量，以在各种阀门样式、尺寸和过程连接中实现最大性能。这些球阀具有一体式耳轴安装球和阀杆，可消除两件式设计常见的剪切故障。阀座压盖可重新拧紧以延长阀座寿命，低摩擦压力辅助石墨填充 PTFE 阀杆密封可降低驱动扭矩并增加循环寿命。这些阀门具有全端口流路，可最大限度地减少压降，并配有 PEEK 阀座，以确保出色的耐化学性、耐热性和耐磨性。

作为标准配置，这些高压球阀由冷加工 316 不锈钢制成，能够在高达 20,000 PSI (1,379 bar) 的压力下运行。接液部件也有其他材料。阀门配有 Viton O 型圈，额定工作温度范围为 -17.8 至 204°C（0 至 400°F）。可选择使用其他 O 形圈材料，以将上限扩展至 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).
