Introduction
Fisher pilot operated regulators are high-performance pressure control devices designed to maintain stable downstream pressure in industrial gas systems.
Unlike direct-operated regulators, pilot-operated designs use a secondary pilot mechanism to control the main valve, enabling higher accuracy, greater flow capacity, and improved stability under varying conditions.
High Pressure Control Accuracy
Maintains outlet pressure within tight tolerances, even under fluctuating conditions.
Large Flow Capacity
Suitable for high-flow industrial systems such as gas transmission and distribution.
Stable Performance
Minimizes pressure drop (droop) and ensures consistent operation.
Fast Response
Quick adjustment to downstream demand changes improves system efficiency.
Tight Shutoff Performance
Prevents leakage and enhances system safety.
Technical Capabilities
Typical performance characteristics include:
Inlet pressure: up to 69 bar (1000 psig) depending on model
01
Wide outlet pressure adjustment range
02
High flow coefficient (Cv) for large capacity systems
03
