Essential Accessories for a Complete Valve Control Assembly
A Fisher digital valve controller delivers the best performance when integrated into a properly engineered instrument assembly. Supporting components such as regulators, switching valves, and compatible control valves play a critical role in maintaining positioning accuracy, pneumatic stability, and long-term reliability.
The following accessories are commonly paired with the Fisher FieldVue DVC6200 to create a dependable and efficient valve control system.
Supply Pressure Regulators: Fisher 67CFR Series
Clean and stable instrument air is essential for accurate valve positioning. The Fisher 67CFR-239 and Fisher 67CFR-226 filter regulators are designed to protect the DVC6200's pneumatic components by removing moisture, oil, and particulates while maintaining consistent supply pressure.
These regulators help improve controller responsiveness, reduce wear, and extend service life in demanding industrial environments.
| Feature | Fisher 67CFR-239 | Fisher 67CFR-226 |
|---|---|---|
| Primary Application | High-capacity air filtration | Standard instrument air filtration |
| Filter Design | High-flow replaceable cartridge | Standard replaceable cartridge |
| Pressure Handling | Broad industrial operating range | Moderate process pressure range |
| Recommended Use | High-demand control loops | General process applications |
| Maintenance Interval | Extended service cycles | Routine periodic maintenance |
Facilities operating high-cycle control loops or demanding pneumatic applications typically choose the Fisher 67CFR-239 because its high-capacity filtration helps maintain stable instrument air quality under continuous operations. On the other side, Fisher 67CFR-226 is well-suited for standard process control service.
Correct regulator selection helps maintain long-term positioning accuracy and prevents premature wear and tear within the Fisher FieldVue DVC6200.
Switching Valves: Fisher 167DA
The Fisher 167DA switching valve is commonly used in split-range and dual-signal control systems where multiple pneumatic signals must be managed efficiently.
It automatically routes the appropriate signal to the valve controller based on process conditions, enabling flexible control strategies without adding unnecessary field wiring complexity.
This makes the Fisher 167DA switching valve particularly valuable in applications requiring coordinated valve sequencing or redundant control logic.
Pressure Regulators: Fisher 627 and MR95
Stable downstream pressure is essential for maintaining consistent performance across multiple pneumatic control loops.
The Fisher 627 regulator is widely used to provide reliable pressure control for instrumentation and pneumatic valve assemblies. It delivers a steady supply pressure even under various process demand conditions.
For medium-pressure applications requiring tighter regulation tolerances, the Fisher MR95 Series Regulators offer highly accurate pressure control and dependable responsiveness.
Together, these regulators help support the stable operation of the Fisher digital valve controller platform in complex process systems.
Compatible Control Valves: Fisher D4 and 1301F-2
The Fisher D4 control valve is a compact, high-performance sliding-stem valve engineered for compatibility with FIELDVUE digital positioners. Its responsive design makes it ideal for throttling applications that require accurate flow control and fast actuator response.
For utility systems and auxiliary process loops, the Fisher 1301F-2 provides dependable control in low-to-medium pressure applications where stable throttling performance is required.
When paired with the Fisher FieldVue DVC6200, these valves create an intelligent valve assembly capable of delivering both precision control and advanced diagnostics.
