Cryogenic propellant valves for rocket
propulsion systems.
Valves for the isolation, control and regulation of cryogenic propellants
and pressurant.
Our range of cryogenic valves for rocket propulsion systems are designed
for use with liquid oxygen, liquid hydrogen and associated pressurants.
Flight proven cryogenic valves are available for such functions as propellant
fill and drain, pressurant gas shut-off and venting, propellant isolation
and flow, pressure control, latch valve functions and their digital control.
The valves operate at a temperature range from 1.5 to 350 K and a pressure
range from vacuum to 150 bar and are compatible with cryogenic propellants,
MON-1 and MMH:
We supply cryogenic propellant valves for the core stage propellant tanks
of Ariane 5 for the control of propellant tank pressure and the supply
of LOX and LH2 propellants to the Vulcain
rocket engine. Each flight set of valves for Ariane 5 comprises 6,000 parts,
produced with 1,600 production directives.
We also produce propellant valves for the HM
7 rocket engine and the Vinci
rocket engine which will be used for powering the new cryogenic upper stage
of Ariane 5.

Liquid Helium Valve
|
 |
The liquid helium valve is located between the
liquid helium tank and the LOX tank. The function of the valve
is to shut-off the LOX tank pressurisation line and to enable
the venting of the liquid helium tank.

LOX / LH2 Main Valve
|
 |
The LOX and LH2 Main Valve is located in the
LOX and LH2 feed lines of the Ariane 5 main stage. The function
of the valves is to isolate propellant flow from the main engine
until the launcher is ready for lift-off.

Monostable Latch
Valve
|
 |
The monostable latch valve controls pressure
within the liquid hydrogen tank. Three valves are required for
the Hydrogen Pressurisation plate, shown below.

Hydrogen Pressurisation
Assembly
|
 |
The Hydrogen Pressurisation Plate is an assembly
of three electrically controlled monostable latch valves.
The plate is located between the LH2 propellant tank and Vulcain
engine of the Ariane 5 main stage.
The function of the plate is the digital control of the LH2
propellant tank

LOX / LH2 Isolation
Valve
|
 |
The LOX and LH2 Isolation Valves are located in the fill and
vent lines of the Ariane 5 main stage.
The valves are used to enable filling, draining, pressurisation
and depressurisation of the main stage propellant tanks.

More
Details
|
The high pressure cryogenic propellant valve is a new generation
of valve designed for future high performance applications such
as the Vinci
expander cycle rocket engine.
The valve is also ideally suited for such applications as cryogenic
fluid handling and rocket engine test stands.
