Double stage gas regulators
ERG-SR is a double stage gas pressure regulator with shut-off valve; it grants higher precision and control in gas pressure management in specific applications.
This type of pressure regulator is equipped with two adjustment stages: a first and a second stage
The first stage is designed to control the gas inlet pressure – and its functionalilty is similar to other pressure regulators. The second stage is meant to grant the accuracy and stability of pressure control.
After passing through the first stage, the gas enters the secondy one, which can be equipped with a shut-off-, and also an overflow valve. The shut-off- and overflow valves can be manually reset; they completely close the gas flow in emergency case or when exceeding the set pressure or flow limits. These safety functions are particularly important in applications where gas flow needs to be interrupted quickly in the event of an emergency or hazardous situation.
Basically, a double stage gas pressure regulator provides more precise and reliable control of gas pressure due to the two control stages and the possibility to bshut-off the gas flow completely, if needed. These regulators are often used in civil and industrial applications requiring highly safe and controlled gas pressure management.
