Chemical Industry Valve Challenges
Chemical and process industries handle toxic, corrosive, flammable, and expensive fluids where any valve leakage has serious safety, environmental, and financial consequences. Fugitive emission regulations are tightening, corrosive media degrades standard valve materials, and precise process control directly impacts product quality and yield.
KSB’s bellow seal valve range eliminates fugitive emissions, while stainless steel and alloy body options resist the most aggressive chemicals. MIL control valves provide the precision needed for reactor feed, distillation, and dosing applications.
Valve Solutions by Application
| Application | Valve Requirement | KSB Product |
|---|---|---|
| Toxic/hazardous fluids | Zero fugitive emission | ECOLINE BSGT-S/BSGL-S bellow seal (316 Ti bellows) |
| Corrosive media isolation | SS body, tight shut-off | SICCA gate valve (CF8M/F316) |
| Throttling / regulation | SS globe, precise control | SICCA globe valve (CF8M) / MIL 21000 |
| Reactor feed control | Precise, wide range | MIL 41000 cage guided control valve |
| Distillation column | Temperature / pressure control | MIL 21000/27000 post guided / compact |
| Chemical dosing | Micro-flow precision | MIL 29000 Micropak (500:1 rangeability) |
| Slurry / viscous media | Shearing action, anti-clog | MIL 35500 V-notch segmented ball |
| Vacuum service | No air ingress | ECOLINE bellow seal globe (BSGL-S) |
| Chlorine / ammonia | Zero emission, corrosion proof | Bellow seal + SS/alloy construction |
| LPG / LNG handling | Fire-safe, zero leak | ECOLINE bellow seal gate (BSGT-S) |
