    UHP 超純PFA氣動隔膜(1“)2通閥 – PV-12系列 UHP PFA Air-operated Diaphragm (1 inch) 2 Way Valve – PV-12 Series

    PV-12 系列 PFA隔膜閥提供高泄露完整性和優異的耐腐蝕性。非常適合用于超高純(UHP)和腐蝕性流體應用。有2通和3通型 。The PV-12 Series PFA Diaphragm Valve offers high leak integrity and exceptional corrosion resistance. It is ideally suited for use in ultra-high purity (UHP) and aggressive fluid applications. Available in 2-way and 3-way configurations.

    PV-12系列是1PFA氣動隔膜閥,用于超高純(UHP)和腐蝕性氣體和液體處理系統,包括用于半導體制造操作。閥門有2通和3通型。3通型帶有多功能安裝底座,允許更多的安裝靈活性,減少接頭的使用,使它們有利于在空間受限區域使用。The PV-12 Series is a 1 inch PFA air-operated 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 operations. The valve is available in 2-way and 3-way configurations. The 3-way configurations have a multi-position mounting base, which allows for more mounting flexibility and connector fitting reduction, making the advantageous in areas where workable space is limited.

    PV-12系列具有成型PFA閥體和精密加工密封區域。利用氟聚合物涂層不銹鋼彈簧減少腐蝕性環境的影響,可與廣泛的腐蝕性工藝介質兼容。閥門還配備了一體式改性聚四氟乙烯隔膜,提供較之傳統PTFE聚四氟乙烯更高的循環壽命。根據客戶需求,PV-12系列閥門可配套多種接口形式,包括Parflare和Parbond管接頭。Parflare和Parbond接頭節約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。 The PV-12 Series features a molded PFA body with precision-machined sealing areas. It utilizes 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 valve is also equipped with a one-piece modified PTFE diaphragm, which provides higher cycle life when compared to conventional PTFE. Depending on customer requirements, the PV-12 Series valve can be fitted with a variety of port configurations, including Parflare and Parbond tube fittings. Both Parflare and Parbond fittings reduce assembly time and installation costs, while ensuring a leak-tight seal for reliability in applications where cleanliness is critical.

    PV-12系列的榫槽密封以獲得隔膜與閥體的穩定密封,形成更高的泄漏的完整性、更低的維修成本,和與工藝介質的隔離。此系列1”全通徑提供緊湊型結構的流量上限(PV-12 Parbond接口上限15.7CV)。流量取決于結構和接口形式。閥門雙向額定壓力100psig,動作壓力范圍60 – 100 psig。 The tongue and groove seal of PV-12 Series valves ensures a positive diaphragm to body seal, resulting in superior leak integrity, lower replacement costs, and isolation of process media from the actuator. The series' full 1 inch orifice offers maximum flow capability in a compact package (up to 15.7 C v for PV-12 with Parbond). Flow capacities are dictated by configuration and end type. The valve is bidirectionally pressure rated at 100 psig and has an actuation pressure range from 60 – 100 psig.

    PV-12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-12 Series is available with a submergible option, which isolates components from the external environment and allows the valve to remain functional while operating in wet or gaseous corrosive environments.
