Introduction
Fisher direct acting regulators are self-operated pressure control devices designed for fast response and simple operation. These regulators directly sense downstream pressure through a diaphragm and spring mechanism, eliminating the need for external pilot systems.
Fast Response Mechanism
Direct diaphragm sensing enables immediate adjustment to downstream pressure changes, ensuring system stability.
Simple Self-Operated Design
No external pilot system required. Fewer components reduce failure rate and simplify maintenance.
Wide Pressure Range
Supports inlet pressures from low pressure up to several hundred bar depending on model, with flexible outlet pressure settings.
Corrosion-Resistant Materials
Available in stainless steel, ductile iron, and alloy materials for harsh environments.
Built-in Safety Features
Includes internal relief valves and overpressure protection to ensure safe operation.
