Parker派克PV-1 系列 UHP PTFE 气动微型隔膜 2 通或 3 通阀 1/8 英寸
UHP PTFE Air-operated Miniature Diaphragm 2 Way or 3 Way Valve (1/8 inch) – PV-1 Series

PV-1 系列气动 PTFE 微型隔膜阀具有高循环寿命和出色的耐腐蚀性。它是超高纯度 (UHP) 和腐蚀性流体应用中低流量和/或小剂量注射的理想选择。PV-1 系列是 1/8 英寸气动（气动）微型隔膜阀，提供 2 通和 3 通配置。它具有机加工改性的 PTFE 主体、阀座和隔膜，可提供高弯曲寿命、出色的泄漏完整性和出色的耐腐蚀性。该阀非常适用于超高纯度和腐蚀性化学和气体分配系统中的低流量和小剂量注射，包括分析、DNA 测序和半导体制造应用。PV-1 系列阀门的严格设计控制阀座和隔膜应力，以提供可靠且免维护的使用寿命。其舌槽密封确保膜片与阀体之间的正密封，从而降低更换成本并将过程介质与执行器隔离。PV-1 系列执行器本身非常紧凑，工作压力低至 20 psi，易于安装和维护。PV-1 系列的正向和反向压力额定值从真空到 20 psig。

The PV-1 Series Air-operated PTFE Miniature Diaphragm Valve offers high cycle life and excellent resistance to corrosion. It is ideal for low flow and/or small dose injection in ultra-high purity (UHP) and aggressive fluid applications. The PV-1 Series is a 1/8 inch air-operated (pneumatic) miniature diaphragm valve that comes available in 2-way and 3-way configurations. It features a machined modified PTFE body, seat, and diaphragm, which afford high flexural life, excellent leak integrity, and exceptional resistance to corrosion. The valve is ideally suited for low flow and small dose injection in ultra-high purity and aggressive chemical and gas distribution systems, including analytical, DNA sequencing, and semiconductor manufacturing applications. The PV-1 Series valve's exacting design controls seat and diaphragm stresses to provide a reliable and maintenance free service life. Its tongue and groove seal ensures a positive diaphragm to body seal, resulting in lower replacement costs and isolation of process media from the actuator. The PV-1 Series actuator itself is highly compact and works on as little as 20 psi for ease of installation and maintenance. The PV-1 Series is pressure rated from vacuum to 20 psig in both the forwards and backwards direction.
