KLINGER CS (Carbon Steel) Piston Valve is a high-performance industrial valve specially designed for steam, condensate, thermal oil, gas, and process fluid applications. It is known as a seatless and glandless valve, offering leak-proof shut-off, long life, and very low maintenance. It works using a stainless steel piston moving through sealing rings, ensuring tight sealing both internally and to atmosphere.
🔧 Key Features
- Carbon Steel Body (Cast Steel / WCB) – strong and suitable for high-pressure service
- Seatless & Glandless Design – eliminates conventional seat leakage
- Double Sealing Rings (KX-GT Rings) – ensures tight shut-off and no stem leakage
- Excellent for Steam Applications – ideal for steam and condensate lines
- Fire Safe Design – suitable for critical industrial services
- Low Maintenance – no erosion of sealing surfaces
- Can Replace Gate + Globe Valve Functions in many applications
- Revisable Without Removing from Line
