Cobham's oxygen valve line includes a variety of high and low pressure valves designed to allow for the safe control of oxygen, both gaseous and liquid. These products are in use in a variety of commercial and military applications.
The Filler Valve Manifold (part number B42782-1) in military aircraft interfaces with the oxygen system to allow controlled recharging of the oxygen storage vessels. Advantages include less system refilling maintenance, a built-in flow restrictor, and ability to be removed from the manifold and replaced without disconnecting aircraft tubing.
The Oxygen Bleed Valve assembly (part number B19820) features a lightweight, compact design with an in-line configuration. When actuated as part of pre-fight checks, it safely vents oxygen from the low-pressure distribution line to demonstrate operational integrity of the upstream gaseous oxygen supply.
The Riser Line Shut-Off Valve (part number B43902-1) is an integral part of an aircraft's gaseous passenger emergency oxygen system. The valve, or flow fuse, isolates a section of the emergency oxygen system in the event a severed distribution line allows oxygen flow to exceed normal operating levels.
The Oxygen Manifold and Check Valve Assembly (part number B40831-1) is an integral component in military aircraft oxygen life support systems. The manifold and check valve assembly directs oxygen flow to the storage vessels during filling and to a downstream system pressure regulator during operation.
The Series/Parallel Relief Valve (part number B43577-1) is an integral part of an aircraft gaseous emergency passenger oxygen system. The valve prevents excessive pressure build up in the oxygen system in the event of an uncontrolled pressure rise.
The 2239 Series Oxygen Regulator Refill Valve provides breathing oxygen for distribution to crew stations on large commercial aircraft. This assembly has been approved for installation on DC-10, MD-10, and 767 aircraft.
The 2279 Series Oxygen Filler Valve provides a remote fill capability for aircraft gaseous oxygen systems. The valve features temperature compensation and automatic shut-off and has been approved for installation on 727, 737, 747, 757 and 777 aircraft.
