37.12 Pressure regulators
The internal pressure regulators protect the system from too high external gas pressures
that would damage the gas circuit's sensitive parts. If the pressure regulators are worn, they
may begin to drift and not offer the protection they are supposed to. It could cause
breakdowns or leaks in the internal gas circuit. Therefore, the regulators must be replaced
once every 4
years to maintain the system safe and stable.
