WWW.DISTRIBUTORALATIDUSTRI.COM | Supplier Fisher EZR Pressure Regulator, Jakarta | Fisher EZR Pressure Regulator is a pilot-operated pressure-reducing regulator manufactured by Fisher / Emerson, designed for accurate and reliable control of gas pressure in high-capacity industrial and gas distribution systems. The EZR is widely used where stable downstream pressure and high flow capacity are required.
Supplier Fisher EZR Pressure Regulator, Jakarta

The Fisher EZR is a spring-loaded, pilot-operated regulator designed to reduce high inlet pressure to a controlled downstream pressure. Its pilot-operated construction provides excellent pressure control and high capacity while maintaining relatively stable outlet pressure under varying flow conditions.
The EZR is particularly suitable for natural gas and other clean, non-corrosive gases used in transmission, distribution, commercial, and industrial applications.
Working Principle
The EZR uses a pilot control system to operate the main valve.
- High-pressure gas enters the regulator.
- A portion of the gas is directed through the pilot system.
- The pilot senses downstream pressure.
- When downstream pressure falls below the set point, the pilot changes position and increases loading pressure on the main diaphragm.
- The main valve opens further, allowing increased gas flow.
- As downstream pressure reaches the set point, the pilot adjusts the loading pressure and the main valve moves toward the required position.
- This continuous modulation maintains the desired downstream pressure.
Because the pilot controls the main valve, the EZR can achieve higher capacity and more accurate pressure regulation than many conventional direct-operated regulators.
