    NV70是經濟、通用、高流量隔膜閥,非常適合大量的腐蝕性和非腐蝕性流體。這款緊湊型、316L不銹鋼閥門可獲得穩定和一致的手動或氣動關閉。NV70使用高抗疲勞強度膜片 (Elgiloy?) 形成外部金屬密封,提供了對大氣的穩定密封。內部無螺紋和彈簧。高循環壽命。緊湊型尺寸?煽、一致關閉 與大氣金屬對金屬密封。經過吹掃,可用于氧環境。高流量應用的理想選擇。壓力范圍:AOPLPNO氣動低壓常開 / AOPLPNC氣動低壓常閉 閥門,真空到150 psig for;手動閥250 psig。 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.
