Parker派克PR系列球阀，旋塞阀
Parker's PR Series Plug Valves

派克 PR系列旋塞阀，闭合严密，大流量，快速旋转四分之一转开关操作，结构紧凑。此款阀门也为用户提供了优异的节流能力。派克的PR系列旋塞阀，结构紧凑，大流量，快速四分之一圈操作并保证关断的气密性。防吹出专利阀座设计确保在工作压力范围内提供可靠的密封性，普通的旋塞阀是无法实现此功能的。除了开关作用外，旋塞设计还可以实现节流作用。阀座和密封材料的多种选择用以满足介质的兼容性要求以及工作温度范围。PTFE 支撑阀体密封材料，确保可靠密封，同时延长了其循环使用寿命。

Parker's PR Series Plug Valves provide positive leak tight shut-off, high flow capacity, and quick quarter-turn operation in a compact, barstock body. This plug valve provides the user the ability to throttle during manual actuation.Parker’s PR Series Plug Valves provide positive leak tight shut-off, high flow capacity, and quick quarter-turn operation in a compact attractive package. The patented blow-out resistant seat design offers reliable sealing technology at all operating pressures not seen in general purpose plug valves. In addition to on-off actuation, the plug design allows forward flow throttling. A broad selection of valve seats and seal materials may be chosen for media compatibility and performance over a broad range of temperatures. The pressure balanced atmospheric seals are backed by PTFE rings to enhance their performance and increase cycle life.
