LOX FILL, BUILDUP AND VENT VALVE

The LOX Fill, Buildup and Vent Valve is a semi-automatic valve that provides a safe means to control flow during filling operation of liquid oxygen converters. A specially-designed valve connection mates with standard LOX ground handling devices. When coupled to this device, the internal valve mechanisms simultaneously allow for the venting of oxygen gas within the converter and the transfer of liquid oxygen into the converter. When disconnected, these mechanisms automatically close, allowing the pressure build-up process to begin. The Essex LOX Fill, Buildup and Vent Valve is a CRU-50/A connection and is QPL approved to MIL-V-25961.

LOX CHECK VALVE

The LOX Check Valve is designed to operate with either liquid or gaseous oxygen.  An elastomer seal ensures zero leakage when the application  involves gaseous oxygen.  The valve has an operating pressure of 300 psi and a temperature range of -300°F to +260°F.

LOX FILLER VALVES

LOX Filler Valves are specifically designed to service liquid oxygen (LOX) systems for military aircraft.  They automatically open and close when activated by the mating component.  Pin quantity and size variations are provided for proper coupling.  Valves can be modified to meet specific customer requirements. These LOX valves are designated as CRU-59/E.  They perform in accordance with MIL-PRF-38201.

HYDRAULIC CHECK VALVE

Hydraulic Check Valves range in size from 1/4″ to 2″ and are available with a variety of standard or custom end fittings.

CRYOGENIC RELIEF VALVE

The Cryogenic Relief Valve series is designed for use on Air Force and Navy liquid oxygen converters as well as other cryogenic systems.  Valves are vailable in a wide range of pressure settings to accommodate a variety of system requirements.  Meets all MIL-PRF-9050 requirements.  Stainless steel ball and a Teflon seat arrangement provides zero leakage at re-seat pressures.  ANPT threaded inlet and outlet ports, internal filter and corrosion resistant steel construction.

ANTI-GRAVITY VALVE

The Anti-Gravity Valve (Anti-G Valve) is a durable, pneumatic pressure-regulating valve that automatically reacts to positive G-forces acting on the aircraft and crew members. During heavy G-inducing maneuvers, such as a high-speed tight turn or rapid climb, the aircrew blood supply will leave the head and upper extremities. Prolonged exposure to this condition will eventually result in G-induced loss of consciousness, or G-LOC. The Anti-G Valve senses these G-forces and allows ECS-conditioned air to pressurize the pilot’s anti-G suit abdominal and leg bladders to restrict blood from pooling in the lower extremities. When the G-force is relieved, the valve automatically opens, allowing suit pressure to vent back to ambient. Essex Anti-G Valves are QPL-approved to MIL-V-9370, MIL-V-87223 and MIL-V-87255, and can be found in most high-performance US military aircraft as well as trainers, light attack aircraft and combat fighters throughout the world.

AIR SELECTOR VALVE

The Air Selector Valve is a two position on/off valve that selects between two different pressure or vacuum sources to run instruments on an aircraft.

MOUNTING BASE BRACKET

The Mounting Base Bracket is designed as a mount for liquid oxygen converters and OBOGS systems in aircraft. Made of corrosion resistant steel.  Hole placement can be modified to meet specific customer requirements.  Conforms to MS90341.

CRYOGENIC HIGH PRESSURE CLOSING VALVE

Cryogenic High Pressure Closing Valves are designed for use on Air Force and Navy liquid oxygen converters as well as other cryogenics systems with operating pressures of less than 300 PSIG.  The pressure closing valve allows the cryogenic system to maintain operating pressure while in use.

CRYOGENIC LOW PRESSURE CLOSING VALVE

Cryogenic Low Pressure Closing Valves are designed for use on Air Force and Navy liquid oxygen converters as well as other cryogenics systems with operating pressures of less than 130 PSIG.  The pressure closing valve allows the cryogenic system to maintain operating pressure while in use.
