Working Principle
The Fisher 912 uses a diaphragm-and-spring mechanism to control the main valve.
- Gas enters through the inlet at a higher pressure.
- The regulator reduces the gas pressure through the internal valve.
- Downstream pressure acts on the sensing diaphragm.
- The diaphragm continuously balances downstream pressure against the spring force.
- When downstream pressure decreases, the valve opens to increase gas flow.
- When downstream pressure increases toward or above the set point, the valve closes to reduce gas flow.
This automatic action maintains the downstream pressure around the desired set point.
Typical Applications
Fisher 912 regulators are suitable for applications such as:
- Natural gas distribution
- Fuel gas supply
- Gas-fired burners
