Operating Principle

The Fisher Type 98H regulator operates using a spring-loaded diaphragm assembly that automatically balances outlet pressure against the adjustable spring force. When downstream pressure decreases below the setpoint, the regulator valve opens to increase flow. As outlet pressure rises to the desired setting, the valve throttles toward the closed position, maintaining stable downstream pressure throughout the system.

Advantages

  • High-capacity flow performance

  • Excellent pressure stability and sensitivity

  • Reliable operation under varying loads

  • Minimal maintenance requirements

  • Durable industrial-grade construction

  • Flexible installation capability

  • Proven Fisher regulator reliability
