Parker High Flow, Compact Size Diaphragm Valve - NV70 Series
NV70 系列高流量緊湊型隔膜閥 | #54021227
High Flow, Compact Size Diaphragm Valve - NV70 Series | #54021227
PARKE NV70 是一種經(jīng)濟(jì)型、通用型、高流量隔膜閥，非常適用于流動大量腐蝕性和非腐蝕性流體。NV70 是一種經(jīng)濟(jì)型、通用型、高流量隔膜閥，非常適用于流動大量腐蝕性和非腐蝕性流體。這種緊湊的 316L 不銹鋼閥門可確保通過手動或氣動驅(qū)動實(shí)現(xiàn)可靠且一致的關(guān)閉。NV70 使用高疲勞強(qiáng)度隔膜 (Elgiloy)，形成外部金屬密封，并提供可靠的大氣密封。內(nèi)部無螺紋和無彈簧。高循環(huán)壽命。緊湊的尺寸。積極、一致的關(guān)閉。金屬對金屬密封到大氣。為 O2 服務(wù)清潔。高流量應(yīng)用的理想選擇。從真空到 AOPLPNO / AOPLPNC 閥門的 150 psig 和手動閥門的 250 psig 功能齊全。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.
