    Parker PFA閥
    Parker PFA Valves
    UHP 超高純 PFA氣動隔膜(1/2 ") 3 通閥 – PV-11系列 UHP PFA Air-operated Diaphragm (1/2 inch) 3 Way Valve – PV-11 Series

    PV-11 系列 PFA閥提供高泄露完整性和優異的耐腐蝕性。有2通和3通型,用于超高純(UHP)和腐蝕性流體應用 The PV-11 Series PFA Valve offers high leak integrity and excellent resistance to corrosion. It is available in 2-way and 3-way configurations and is designed for ultra-high purity (UHP) and aggressive fluid applications (up to 100 psig).

     

     

     

     

     

    PV-11系列是1/2氣動(AOP) PFA隔膜閥,用于超高純(UHP)和腐蝕性氣體和液體處理系統,包括半導體制造和潔凈區域操作。閥門有2通和3通型,采用成型PFA閥體和精密加工區域,形成更好的泄漏完整性和耐化學性。配備多功能安裝底座,3通型允許更多的安裝靈活性,減少連接件的使用, 使它們有利于在空間受限區域使用.The PV-11 Series is a 1/2 inch air-operated (AOP) PFA diaphragm valve that is designed for use in ultra-high purity (UHP) and aggressive gas and liquid handling systems, including those used in semiconductor manufacturing and clean-area operations. The valve is available in 2-way and 3-way configurations and utilizes a molded PFA body with precision-machined sealing areas for superior leak integrity and chemical resistance. With a multi-position mounting base, the 3-way configurations allow for increased mounting flexibility and connector fitting reduction, making them advantageous in areas where workable space is limited.

    PV-11系列PFA閥門采用氟聚合物涂層不銹鋼彈簧,減少腐蝕性環境的影響,以適應與廣泛的腐蝕性工藝介質兼容。閥門還配備一體式改性聚四氟乙烯隔膜,提供較之傳統聚四氟乙烯更高的循環壽命。為增加靈活性,PV-11系列可配套多種連接方式,包括Parflare和Pargrip管接頭。接頭減少了裝配時間和安裝成本,以獲得潔凈至關重要的應用中無泄漏密封的穩定性. PV-11 Series PFA valves feature a Fluoropolymer-coated stainless steel spring which reduces the effects of corrosive environments and ensures compatibility with a wide range of aggressive process media. The valves are also equipped with a one-piece modified PTFE diaphragm, which provides higher cycle life when compared to conventional PTFE. For increased flexibility, the PV-11 Series can be fitted with a variety of port configurations, including Parflare and Pargrip tube fittings. The fittings reduce assembly time and installation costs, while ensuring a leak-tight seal for reliability in applications where cleanliness is critical.

    PV-11系列閥門的榫槽密封提供隔膜和閥體的穩定密封,形成高循環壽命。它的1/2全通徑對緊湊結構的大流量無限制。流量變黃取決于接口尺寸和結構類型(可大至3.7 C?v).The tongue and groove seal of the PV-11 Series valve ensures a positive diaphragm to body seal, resulting in high cycle life. Its full 1/2 inch orifice offers maximum flow capability in a compact package. Flow capacities vary depending on port size and configuration type (up to 3.7 C?v).

    PV-11 系列可選潛水型,隔離元件與外部環境,使閥門在潮濕或氣體腐蝕性環境下工作時保持功能. The PV-11 Series is available with a submergible option, which isolates all valve components from the external environment and allows the valve to remain functional while operating in wet or gaseous corrosive environments.
