Operating Principle

The Fisher Type 1301G regulator uses a spring-loaded diaphragm mechanism to maintain constant outlet pressure. As downstream pressure decreases, the regulator valve opens automatically to increase flow. When downstream pressure rises to the desired setpoint, the valve throttles toward the closed position, ensuring stable and accurate pressure control throughout the process system.
