I've been tasked with designing a variety of valves for use within a Fuel Metering Unit. Usually we use O-rings for sealing purposes between sleeves and bores.
I'm currenting looking to see if there are any viable alternatives to O-rings, mainly to avoid stepping in the sleeve diameter when a number of seals are required. (Freeze fitting being a non-preferred option).
Typical operating conditions:-
Temp Range: -53 degC to 180degC
Pressure: 800 psi differential
The sleeve will be a hard anodised Al alloy
Does anyone have any suggestions?
