Supplier Fisher T205 Pilot- Operated Backpressure Regulator
WWW.DISTRIBUTORALATINDUSTRI.COM | Supplier Fisher T205 Pilot- Operated Backpressure Regulator | Fisher T205 is a pilot-operated backpressure regulator / relief valve manufactured by Emerson Fisher, designed to maintain a constant upstream pressure by controlling the flow of gas or liquid through the regulator
The Fisher T205 is a high-performance regulator suitable for applications requiring accurate upstream pressure control. It uses a pilot-operated design, allowing the regulator to respond smoothly to changes in system pressure and maintain stable pressure under varying flow conditions.
Supplier Fisher T205 Pilot- Operated Backpressure Regulator
It is commonly used in:
- Natural gas systems
- Gas distribution
- Industrial gas systems
- Process plants
- Fuel gas systems
- Pressure control and relief applications
- Gas transmission and distribution systems
Operating Principle
The T205 senses the upstream pressure through its sensing system.
- When upstream pressure is below the set point, the regulator remains more closed.
- When upstream pressure increases above the set point, the pilot responds and causes the main valve to open.
- The increased opening allows more fluid/gas to pass downstream.
- This reduces upstream pressure back toward the desired set point.
Therefore, the T205 is primarily used for backpressure control, rather than conventional downstream pressure reduction.
Main Features
- Type: Pilot-operated backpressure regulator
- Function: Upstream pressure control / pressure relief
- Manufacturer: Fisher / Emerson
- Series: T200 Series
- Application: Gas and process pressure control
- Control: Pilot-operated
- Design: High-capacity flow path
- Response: Stable and accurate pressure regulation
- Maintenance: Designed for relatively easy inspection and servicing
- Installation: Typically installed in-line with the process piping
Typical Configuration
A Fisher T205 system generally consists of:
- Main valve body
- Pilot
- Diaphragm
- Spring
- Valve plug
- Orifice/nozzle
- Sensing/control line
- Internal/external pressure control components
The pilot controls the main valve based on upstream pressure. This allows the regulator to provide greater capacity and more precise pressure control than many direct-operated regulators.
Advantages
The Fisher T205 offers:
- Stable upstream pressure control
- Good regulation accuracy
- High flow capacity
- Smooth response to pressure fluctuations
- Suitable for demanding industrial applications
- Pilot-operated control for improved performance
- Flexible configuration depending on pressure and process requirements
