Operating Principle
The Fisher 299H regulator operates using a pilot-controlled diaphragm system. The pilot senses downstream pressure changes and amplifies control pressure to position the main valve accurately. When downstream pressure decreases below the setpoint, the pilot opens the main valve to increase flow. As outlet pressure rises, the regulator throttles toward the closed position to maintain stable downstream pressure.
Advantages
Excellent outlet pressure stability
High flow capacity with compact design
Precise pilot-operated control performance
Reliable operation under varying demand conditions
Long operational service life
Reduced maintenance requirements
Suitable for industrial and utility gas applications
