Parker High Flow, Compact Size Diaphragm Valve - NV70 Series
NV70 系列高流量紧凑型隔膜阀 | #54021227
High Flow, Compact Size Diaphragm Valve - NV70 Series | #54021227
PARKE NV70 是一种经济型、通用型、高流量隔膜阀，非常适用于流动大量腐蚀性和非腐蚀性流体。NV70 是一种经济型、通用型、高流量隔膜阀，非常适用于流动大量腐蚀性和非腐蚀性流体。这种紧凑的 316L 不锈钢阀门可确保通过手动或气动驱动实现可靠且一致的关闭。NV70 使用高疲劳强度隔膜 (Elgiloy)，形成外部金属密封，并提供可靠的大气密封。内部无螺纹和无弹簧。高循环寿命。紧凑的尺寸。积极、一致的关闭。金属对金属密封到大气。为 O2 服务清洁。高流量应用的理想选择。从真空到 AOPLPNO / AOPLPNC 阀门的 150 psig 和手动阀门的 250 psig 功能齐全。The NV70 is an economical, general purpose, high flow diaphragm valve ideally suited when flowing large volumes of corrosive and non-corrosive fluids. This compact, 316L stainless steel valve ensures positive and consistent shut off with manual or air actuation. The NV70 uses a high fatigue strength diaphragm (Elgiloy?) that creates an external metal seal, and provides a reliable seal to atmosphere. Internally threadless and springless. High cycle life. Compact size. Positive, consistent shut off. Metal-to-metal seal to atmosphere. Cleaned for O2 service. Ideal for high flow applications. Fully functional from vacuum to 150 psig for AOPLPNO / AOPLPNC valves and 250 psig for manual valves.
