针阀，立式旋塞 6000 PSI - PV 系列 | #4Z-PV4PFA-V-SS

Parker PV 系列立式旋塞阀和仪表/罗茨阀采用螺纹阀盖设计。这些明杆旋塞阀的工作压力高达 6,000 PSI (414 BAR)。由于各种阀座和密封材料，它们可以满足高压和高温应用。Parker 立式旋塞和表压/罗茨阀采用螺纹阀盖设计，可提供多种阀座和密封材料。这些阀门具有阀盖锁定板，以提高阀门安全性。PV 和 PVG 系列阀门提供两种孔径的直通流路。这种“可旋转”功能让用户可以清除脏应用程序或粘性应用程序中的流动流。另外座椅是可以更换的。这些是与一般针型阀相比的巨大优势。

此外，这些阀门采用非湿式上阀杆和非旋转下阀杆以及锥形阀座，即使在颗粒（浆液）介质中也能实现可靠关闭和长阀座寿命。阀盖顶部装有防尘密封件，以确保在使用时没有任何东西从外部环境进入阀杆区域以锁定阀杆旋转。

Parker PV Series Rising Plug and Gauge/Root Valves are a screwed bonnet design. These rising stem plug valves operate up to 6,000 PSI (414 BAR). They can meet high pressure and temperature applications due to various seat and seal materials.

Parker Rising Plug and Gauge/Root Valves are a screwed bonnet design and available with a variety of seat and seal materials. These valves feature bonnet lock plates for additional valve safety. The PV and PVG Series of valves provide a straight-through flow path in two orifice sizes. This “roddable” feature lets the user clean out the flow stream in dirty or a sticky application. Plus the seat is replaceable. These are tremendous advantages over a general needle style valve.

In addition, these valves utilize a non-wetted upper stem and a non-rotating lower stem in conjunction with a tapered seat for positive shut-off and long seat life, even in particulated (slurry) media. The dust seal is incorporated at the top of the bonnet to insure nothing enters the valve stem area from the outside environment to lock up the stem rotation when in service.
