UHP PFA气动隔膜阀（1英寸）2通阀– PV-12系列
Parker PFA阀 - Parker PFA Valves
UHP PFA Air-operated Diaphragm (1 inch) 2 Way Valve – PV-12 Series

PV-12系列PFA隔膜阀具有很高的泄漏完整性和出色的耐腐蚀性。它非常适合用于超高纯度UHP和腐蚀性流体应用。提供2通和3通配置。PV-12系列是一种1英寸PFA气动隔膜阀，设计用于超高纯度（UHP）以及腐蚀性气体和液体处理系统，包括那些在半导体制造操作中使用的系统。该阀有2通和3通配置。三向配置具有多位置安装基座，可提供更大的安装灵活性并减少连接器装配，在可工作空间有限的区域中具有优势。

PV-12系列具有模制的PFA阀体，并具有精密加工的密封区域。它采用了含氟聚合物涂层的不锈钢弹簧，可减少腐蚀性环境的影响，并确保与各种腐蚀性工艺介质的兼容性。该阀还配备了一件式改良PTFE隔膜，与传统的PTFE相比，具有更长的循环寿命。根据客户要求，PV-12系列阀门可以装配多种口径配置，包括Parflare和Parbond管件。Parflare和Parbond配件都减少了组装时间和安装成本，同时确保了密封性，以确保清洁度至关重要的应用中的可靠性。

PV-12系列阀门的榫槽密封确保了膜片与阀体之间的可靠密封，从而实现了出色的泄漏完整性，较低的更换成本以及过程介质与执行器的隔离。该系列的全1英寸节流孔在紧凑的包装中提供了最大的流量能力（带Parbond的PV-12最高为15.7 Cv）。流量由配置和终端类型决定。该阀的双向额定压力为100 psig，驱动压力范围为60 – 100 psig。

PV-12系列具有潜水选项，可将组件与外部环境隔离，并允许阀门在潮湿或气体腐蚀性环境中运行时保持功能。

UHP PFA Air-operated Diaphragm (1 inch) 2 Way Valve – PV-12 Series

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.

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.

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.

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.

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.
