Product Description
Pinch valves model 206M are designed for the regulation and shut-off of highly abrasive media—such as slurries, powders, or coarse-grained substances, including corrosive media.
One of the main advantages of the valve is its dismountable, two-piece body and the dual-sided hose sleeve clamping mechanism. The open body design significantly facilitates valve maintenance and servicing.
Design features of the model:
- Dismountable body
- Open body
- Straps for hose sleeve stretching
- Dual-sided sleeve clamping
- Quick and easy hose sleeve replacement
- Open body
Recommended for use in plants:
- Chemical industry (processing of corrosive and abrasive materials, transportation of powders, solid particles, disposal of process waste)
- Mining and raw material processing (metal ore slurries, mineral suspensions, quartz sands, flotation and dewatering residues, abrasive and corrosive materials in processing operations)
- Wastewater treatment systems (sediment and sand, raw sewage handling, lime and carbon sludge suspension transfer)
- Pulp and paper industry and others where media contains solids or has abrasive properties
Working media:
- Highly abrasive environments
- Chemically aggressive environments
- Alkalis
- Acids
- Water containing abrasive particles
- Salt solutions
- Coal
- Sand
- Polar solvents
- Silicone oils
- Environments containing fuel oil, crude oil, gasoline
Body material options:
🔹 Ductile iron
- EN-GJS-400-15 / GGG40
🔹 Stainless steel (corrosion-resistant)
- A351 CF8 (1.4308) / AISI 304 / A182 F304 (1.4301)
- A351 CF8M (1.4408) / AISI 316 / A182 F316 (1.4401
🔹 Aluminum
Material of the Flexible Hose (Rubber Sleeve):
| Material | Temperature Range | Properties / Applications |
|---|---|---|
| EPDM | -50 °C to +130 °C | Weak acids and alkalis, salt solutions, contaminated water, sand, mildly abrasive media |
| NR (Natural Rubber) | -40 °C to +80 °C | Highly abrasive media, sand-laden water, coal, slurries |
| NBR (Nitrile Rubber) | -40 °C to +120 °C | Abrasive media, contaminated water, crude oil, fuel oil, gasoline, oils |
| CSM (Hypalon) | -40 °C to +130 °C | Abrasive and chemically aggressive media, contaminated water |
| IIR (Butyl) | -50 °C to +130 °C | Abrasive media, polar solvents, silicone oils, contaminated water |
| NR + Linatex | -40 °C to +85 °C | Highly wear-resistant, weak acids and alkalis, salt solutions, sand, coal |
| SBR | -40 °C to +100 °C | Abrasive media, contaminated water, glycols, acetone |
| FKM (Viton®) | -20 °C to +150 °C | Chemically aggressive media, solvents, high temperatures, abrasive media |
