Civacon MaxAir 气动海底阀 MaxAir 5"x4" High Performance Crude Oil Internal Valve
Civacon's MaxAir II 5x4 Air Operated Emergency Valve

Civacon 独特的整体设计使得安装海底阀时活塞位于贮罐内，可实现更好的耐磨性、降低对环境的影响。
Civacon MaxAir 系列海底阀有着精良的设计，在液体流动通道中没有活动部件，实现了高流速、高落差，保证了最大的效益。活塞上的三重密封确保了最大的可靠性，而且还可以减少了维护。铸件经过精心的设计减轻了重量、改善了流动性,并容易安装在比较紧凑的位置。
改善了化学兼容性的密封
MaxAirmm海底阀符合AP1 1004EN13083标准。他在苛刻的环境中经现场测试，可以承受-40C到66C的温度。
所有MaxAir”海底阀都带有一个紧急切断槽，出厂还装有热(熔)安全塞，以及一个当失去气压时用以手动打开的插拔螺杆。这种耐用、开孔的设计缩短了装料、卸料、维护的时间，因此，装备了MaxAir网的罐车可以有更多的时间执行运输。

MaxAir 5"x4" High Performance Crude Oil Internal Valve

Civacon's MaxAir HP 5"x4" Air Operated Emergency Valve is suitable for both petroleum and crude applications. The MaxAir? HP Series valves are uniquely engineered with no moving parts in the flow path for a superior flow rate.

Civacon's 5x4 MaxAir HP High Performance Emergency Valve is designed with an independent external exhaust, which isolates the valve exhaust from the rest of the system. This valve is compatible with diesel, biodiesel, gasoline, ethanol and methanol. The Viton GFLT seal provides ultimate product compatibility.

This valve features an integrated air inlet that allows the unit to close if it becomes sheared in the result of an accident. It incorporates a frangible shear groove per 49CFR178.345-8 tested per TTMA RP 84. A factory installed fusible plug that will melt at a temperature of 212° F(100° C) allowing the valve to deplete air pressure. Also included is a mechanical jack screw for manual operation in the event of air pressure loss.

Operating Pressure Requirements: Minimum of 70 psi (4.83 bar) operating line pressure to open the valve against 35 psi (2.41 bar) tank pressure for crude applications. 30 psi (2.06 bar) minimum operating line pressure for petroleum applications.

The MaxAir? HP High Performance Emergency Valve conforms with API 1004 and EN 13083 standards.
