Product Specification
F-isher 3582i Electro Pneumatic Valve Positioner Competitive Price Fast Delivery
Product Overview
- Field-proven electro-pneumatic valve positioner for sliding-stem diaphragm control valves, converting 4-20mA DC input into proportional pneumatic output.
- Delivers accurate, fast-responding control with excellent vibration resistance and low steady-state air consumption for energy-efficient operation.
- Supports field-reversible action, accessible zero/span calibration, and rugged housing adapted to harsh industrial environments.
Technical Specifications
| Parameter |
Specification |
| Input Signal |
4 to 20 mA DC, split-range capable |
| Supply Pressure |
0.4 to 2.0 bar (6 to 30 psig) |
| Linearity Accuracy |
±0.6% of full span |
| Ambient Temperature |
-40°C to +85°C (-40°F to +185°F) |
Application Industry
- Oil & Gas: Applied in refineries, pipeline transmission and offshore platforms for process flow regulation.
- Chemical & Petrochemical: Used in distillation columns, reaction vessels and corrosive medium conveying systems.
- Power Generation: Matches boiler feedwater, steam control and flue gas desulfurization systems.
Common Problems & Solutions
- Valve position drift → Re-calibrate zero & span adjustments; tighten loose feedback linkage and cam assembly.
- No / slow pneumatic output → Clean blocked nozzle-flapper mechanism; filter contaminated air supply; verify input signal stability.
- Excessive air consumption → Replace worn EPDM diaphragms and O-rings; seal leaking pneumatic pipe connections.
Replacement Models
- F-isher DVC6200: HART digital positioner with advanced diagnostics, direct intelligent upgrade for 3582i.
- F-isher 3582: Pure pneumatic valve positioner, matching counterpart for pneumatic-only control loops.
- F-isher DVC2000: Compact digital positioner, cost-effective upgrade entry for basic digital control demands.
