LIN Filler Valves are specifically designed to service liquid nitrogen (LIN) 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. Perform in accordance with MIL-PRF-38201.
SPLIT FLAPPER FUEL VALVE
The Split Flapper Fuel Valve provides a gravity filling operation for fuel and prevents backflow in the system. The valve shown is one of three sizes designed and qualified for the F-35 Lightning II fuel system.
In addition to flapper valves, Essex also manufactures poppet, swing-arm and ball valves ranging from ¼” to 2” diameter for checking and relieving aircraft fuel, hydraulic and pneumatic systems.

SOLENOID-OPERATED RADAR COOLING VALVE
The Solenoid-Operated Radar Cooling Valve is designed for pilot operation on the F-16. When opened, it allows cooler ECS air to flow into the avionics bay to prevent electronics from overheating.
ON/OFF OXYGEN VALVE
This Oxygen Valve, used by the aircraft commander and cargo master, is the primary on/off selector for crew and passenger oxygen supply on the C-17.
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.
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.
