Parker 针阀
Parker Needle Valves
QS系列针型阀 Needle Valve, QS Series - 15,000 PSI

派克Autoclave的QS系列针型阀的额定工作压力高达15,000 PSI。棒料阀具有不旋转的上升阀杆设计,以防止在苛刻的应用中发生磨损。Parker Autoclave's QS Series needle valves are rated for operation up to 15,000 PSI. The bar stock valve has a non-rotating rising stem design to prevent galling in severe service applications.

 

派克Autoclave的QS系列针型阀设计为高流量,不旋转的上升杆阀,工作压力至15,000 psi(1034 bar)。这些针形阀采用革命性的单套圈压缩套筒设计(QS),可快速轻松地安装。该阀设计用于Parker高压釜管,尺寸范围为1/4“”至1“”。使用特殊的石墨编织纱盘根(GY),工作温度可以从-100F到650°F(-73°C到343°C)。316不锈钢结构是标准材料,并提供其他选项。这些阀门具有许多功能,可在各种应用中提供可靠且无故障的服务。Parker Autoclave's QS Series needle valves are designed as a high flow, non-rotating rising stem valve, with working pressures to 15,000 psi (1034 bar). These needle valves utilize a revolutionary single ferrule compression sleeve design (QS) for fast and easy installation. The valves are designed to be used with Parker Autoclave tubing in sizes ranging from 1/4"" to 1"". Operating temperatures can go from -100F to 650°F (-73°C to 343°C) with special graphite braided yarn packing (GY). 316 stainless steel construction is the standard material with other options available. Along with their many features these valves provide dependable and trouble free service in wide variety of applications.
