Description
Metso FGV2001 | Fabric Guide Valve for Paper Machines
Dynamic Product Introduction
The Metso FGV2001 is a dedicated fabric guide valve used in paper-machine applications. Metso’s tissue-industry documentation identifies the FGV2001 as a fabric guide valve and describes a compact, fully stainless-steel construction intended for wire-and-felt guiding duty.
Its job is mechanical and pneumatic rather than electronic: the guide system uses pneumatic bellows, with pressure variation used to move the guide mechanism in response to fabric position. Metso specifically describes the FGV2001’s self-cleaning construction as part of its design for wet- and dry-end paper-machine service.
This distinction is important when sourcing it. FGV2001 is not a PLC, DCS module, I/O card, transmitter, or electronic control valve positioner. It is a specialized pneumatic valve used in a fabric-guiding assembly.

Do not add a specific operating pressure, supply-air pressure, port thread, flow coefficient, or temperature rating to the listing unless those values are confirmed from the exact drawing or nameplate. The available Metso material establishes the valve’s function and construction but does not provide enough evidence to safely fill those fields.
How the Works
The belongs to the pneumatic portion of a fabric-guiding system.
Metso’s description explains the operating principle: the guide mechanism uses two bellows, with one maintained at constant air pressure and the other supplied with varying pressure. A guide palm detects movement of the wire or felt toward the tending side or drive side, and the pneumatic system responds accordingly.
That arrangement makes the a very different procurement item from a conventional automated control valve. The valve participates in the mechanical guiding loop rather than providing electronic feedback to a PLC.
For maintenance teams, this means that a replacement should be evaluated together with the complete guide assembly, pneumatic connections, bellows, guide palm, and machine-specific configuration.
Paper-Machine Application
The was designed for fabric guiding on paper machines, where maintaining the correct lateral position of a wire or felt is essential.
Typical locations can include:
- Forming section fabric guidance
- Press-section felt guidance
- Dryer-section fabric guidance
- Other wire/felt guide assemblies
Metso’s documentation specifically discusses improved operation in both wet-end and dry-end paper-machine environments.
A current surplus listing also identifies variants such as and associates them with Metso/Valmet paper-machine equipment. Do not assume the “/150” variant is interchangeable with a plain without checking the machine drawing and valve configuration.
Global Sourcing & Live-Test SOP
1. Inbound Verification
For an , mechanical inspection is more important than electronic bench testing.
Verify:
- marking
- Manufacturer identification
- Stainless-steel body condition
- Bore/port configuration
- Connector and pneumatic fitting condition
- Corrosion or chemical attack
- Thread condition
- Evidence of previous repair
- Any secondary Metso/Valmet identification number
If the unit carries a longer designation such as , record the complete marking rather than shortening it to .
2. Pneumatic Inspection
Inspect the valve for:
- Blocked or contaminated air passages
- Damaged seals
- Sticking mechanical components
- Damaged pneumatic fittings
- Corrosion around connection points
- Leakage under controlled pneumatic pressure
The valve should not be judged solely by exterior appearance. A clean stainless-steel housing can still contain a contaminated or mechanically sticking valve.
3. Functional Simulation
Where the correct test fixture is available, verify pneumatic response under controlled conditions.
A proper evaluation should check:
- Air admission
- Air exhaust
- Valve response
- Leakage
- Repeatability
- Mechanical movement of the associated guide mechanism
Do not claim a complete functional test from a simple visual inspection.
4. Final Preparation
Before shipment:
- Photograph the complete valve.
- Record all markings.
- Protect pneumatic ports against contamination.
- Prevent impact to fittings and threaded connections.
- Use clean packaging suitable for industrial pneumatic components.
- Clearly document whether the item is the valve only or part of a larger guide assembly.
