Decoding the Model Number
A typical Fisher control valve tag might read: Fisher ET 2" 300# WCC with 667 actuator and DVC6200 positioner
- ET — Valve body series (Easy-e, top-guided)
- 2" — Nominal body size
- 300# — ANSI pressure class
- WCC — Body material (cast carbon steel)
- 667 — Actuator series (spring-and-diaphragm)
- DVC6200 — Digital valve controller (positioner)
Fisher Actuator Series
The actuator is often worth as much as or more than the valve body:
| Actuator | Type | Typical Surplus Value |
|---|---|---|
| 657/667 | Spring & Diaphragm (linear) | $200-$3,000 |
| 585C/585R | Spring & Diaphragm (rotary) | $300-$2,500 |
| 1051/1052 | Piston (rotary) | $500-$5,000 |
| 2052 | Electric (rotary) | $800-$8,000 |
| 3610J/3620J | Electro-pneumatic positioner | $200-$1,500 |
| DVC6200 | Digital valve controller | $500-$3,000 |
| DVC2000 | Digital valve controller (newer) | $800-$4,000 |
What Affects Fisher Valve Value
Key factors that determine how much your surplus Fisher valve is worth:
- Trim type — Cavitation-resistant trim (Cavitrol, WhisperFlo) commands premium prices
- Material — Stainless, chrome-moly, and exotic alloys are worth significantly more
- Actuator condition — A working actuator with positioner can double the valve's value
- Documentation — Original spec sheets, calibration records, and MTRs add 10-20%
- Age — Newer models (post-2010) with current positioners are most valuable
- Completeness — Complete assemblies (body + actuator + positioner) sell for more than individual components
