Fluidtecq Knife Gate Valve Range by Application  

1. Unidirectional Knife Gate Valves  

• Best For: Paper pulp, wastewater, chemical processing, and general fluid isolation where flow   

  pressure travels in a single direction.  

• Design Feature: Features a sharp, precision-ground stainless steel gate that cuts cleanly   

  through thick media and seals tightly against a resilient or metal seat on the downstream side.  

2. Bi-Directional Knife Gate Valves  

• Best For: Dual-flow pressure lines, municipal sewage, sludge handling, and systems subject to backflo  

• Design Feature: Engineered with a specialized seat design that ensures absolute,   

  drop-tight sealing regardless of which direction the line pressure is coming from.  

3. Slurry & Fly Ash Severe-Service Valves  

• Best For: Thermal power plants, steel manufacturing, cement factories, and mining tailings.  

• Design Feature: Built with thick, replaceable polyurethane or natural rubber liners   

  and a hardened, Stellited gate edge to withstand extreme abrasion from bed ash, bottom ash, and mineral slurries.  

4. Bonneted Knife Gate Valves  

• Best For: Volatile chemical lines, hazardous gases, vacuum applications, and pharma sectors.  

• Design Feature: The gate is completely enclosed within a pressure-tight, sealed bonnet.   

  This ensures zero fugitive emissions to the atmosphere and maintains structural vacuum integrity.

• Wastewater Treatment: High-efficiency management of thick municipal sludge, grit chambers, and raw sewage.  

• Pulp & Paper: Smooth slicing through high-consistency paper pulp stock and wood chips without clogging.\  

• Mining & Minerals: Exceptional wear life when regulating abrasive iron ore, coal wash, and copper tailings.  

Frequently Asked Questions (FAQ)  

Q: What is the primary difference between unidirectional and bi-directional knife gate valves?  

A: Unidirectional knife gate valves seal against line pressure in only one specific direction, relying on the process pressure to push the gate against the seat. Bi-directional valves utilize specialized seals to provide absolute shut-off regardless of media flow or pressure coming from either side of the valve  

Q: Can Fluidtecq knife gate valves be utilized for throttling or flow control?  

A: No. Knife gate valves are strictly designed for full open or full closed isolation service. Operating a knife gate valve in a partially open position exposes the seat and gate to extreme high-velocity erosion, which will permanently destroy the seal.  

Q: Do you provide custom automation packages?  

A: Yes. Fluidtecq specializes in custom automation. We equip our pneumatic knife gate valves with high-torque double-acting cylinders, solenoid valves, proximity switches, limit switch boxes, and manual overrides tailored to your plant’s control network
