Fisher Emerson Control Valves: Technical Overview and Application
Fisher (Emerson) Control Valves: Engineering Analysis and Application
Fisher control valves, a key asset of the Emerson corporation, set the industry standard in automated flow control of process media. These valves are specialized for working with steam, aggressive gases, and viscous suspensions. EV Group China organizes the supply of the entire model range of Fisher control valves, providing comprehensive engineering support in equipment selection for the oil and gas sector, power generation, and chemical industry, where stable operation under extreme temperatures and pressures is a critical factor.
Key Series and Model Range of Control Valves
Fisher's product line covers solutions for a wide range of process tasks, from general industrial applications to "severe service" systems (operation in particularly harsh conditions).
| Model | Purpose |
|---|---|
| easy-e ET Valve | Universal globe valve for basic throttling and flow control tasks. |
| easy-e EZ Valve | Designed for low-pressure applications with increased resistance to cavitation damage. |
| easy-e ED Valve | Intended for systems with high differential pressures, including superheated steam lines. |
| easy-e ES Valve | Specialized design for operation in high temperature and pressure conditions. |
| easy-e EW Valve | Used in critically important steam circuits and power generation facilities. |
For media causing intense abrasive wear or a high risk of cavitation, EV Group China recommends using specialized Fisher valve series:
| Model | Purpose |
|---|---|
| EH Series Valve | Design with enhanced resistance to erosive wear and cavitation. |
| HP Series Valve | For ultra-high pressure circuits in the fuel and energy complex. |
| D & DA Valve | Globe valves with reinforced design for heavy-duty operation. |
| D4 Valve | Compact "severe service" valve with optimized flow characteristics. |
Cryogenic valve modifications (easy-e Cryogenic, EWT-C, EZ-C, ET-C series) provide seal class A and positioning accuracy at temperatures down to -196°C, which is critical for LNG production.
Specialized Angle and Segmented Ball Valves
Fisher angle valves are designed for precise flow control in drainage systems and installations with high-velocity media. Segmented ball valves (Vee-Ball series) combine the functionality of an isolation and control element, demonstrating high efficiency when working with media containing fibrous inclusions and abrasive particles.
Integrated Solutions for Automation and Diagnostics
In addition to valves, EV Group China supplies intelligent components for building closed-loop control systems and predictive diagnostics:
- FIELDVUE digital valve controllers with HART and Foundation Fieldbus protocol support for implementing predictive diagnostics and self-diagnostics.
- ValveLink software for analyzing valve performance within the Plantweb architecture, allowing the detection of performance degradation before failure.
- ASCO electromagnetic (solenoid) valves for high-speed control of control medium supply to the pneumatic actuator.
