The 6L steel cylinder is durable and reliable with several options of cylinder valves:
Excess Flow Valve (EFV) = Reducing the air flow from the cylinder in case of damage or unintentional opening.
Safety ratchet = Mechanism preventing unintentional closing, "pull-to-close" or "push-to close".
Pressure gauge = Integrated small pressure gauge showing cylinder pressure.
Burst disc = A pressure relief device that protects the cylinder from overpressurization.

The following cylinder valve combinations are available.

• In-line variant with hand wheel pointing straight down from the cylinder.
  1. Basic version
  2. EFV + safety ratchet
   
• 90° variant with hand wheel angled 90° from the regulator connection. 
  Comes as standard with burst disc and safety ratchet.
  1. Basic version
  2. Pressure gauge and EFV
   
• 180° variant with hand wheel angled 180° from the regulator connection.
  Comes as standard with burst disc and push-to-close safety ratchet.
