Design features

Three jobs.
Precision at
every stage.

Between the gas and the outside world, there is only the valve. Every Orson design starts with the three things it must get right.

01
Seal
Designed for reliable gas-tight performance through demanding service conditions.
02
Dispense
Opens smoothly and closes positively, fill after fill.
03
Relieve
Where fitted, vents safely the moment pressure climbs too high.
Pressure relief
Applicable LPG cylinder valve connections
Overfill protection
EN 549
Seal materials
Inside the valve

Six parts. One job.

Tap any part of the cutaway to see what it does. Shown: a compact valve with pressure relief.

01
Forged brass body
Hot-forged from brass to EN 12164/65 and machined to microns. It carries every other part and takes the full cylinder pressure.
02
Inlet thread
The tapered thread that screws into the cylinder neck and seals metal-to-metal — made to the thread your cylinder needs.
03
Main seal
Elastomer seal to EN 549, tested in-house for n-pentane, ozone and hardness. It is what keeps the gas in.
04
Spindle & spring
The self-closing heart of the valve. The spring holds it shut until a regulator presses it open — remove the regulator and it closes itself.
05
Outlet connection
Machined to the EN 15202 profile your market uses, so the regulator clicks on correctly every time.
06
Pressure relief valve
Set as per EN 13953. If cylinder pressure ever climbs too high, it vents safely, then re-seals.
