Flanged Ball Valve KH155 – Stainless Steel and Carbon Steel with TA-Luft, Fire Safe and ATEX
The ball valve with a flanged connection, PN10/16/25/40 type KH155, is a versatile industrial ball valve for shut-off and control tasks in process, chemical and power engineering. The stainless steel flanged ball valve 1.4408 and the carbon steel flanged PN10- PN40 ball valve 1.0619 both feature a TFM 1600 ball seat, TA-Luft approval, Fire Safe testing and ATEX certification – one of the most comprehensive certification packages available.

TA-Luft, Fire Safe, ATEX and SIL 3 – Certifications in Detail
- TA-Luft: low-emission stem seal per VDI 2440 – mandatory in many chemical and petrochemical plants to reduce VOC emissions.
- Fire Safe: fire-tested per ISO 10497 – valve remains tight and functional even after flame exposure.
- ATEX: II 2G Ex h IIB T3 Gb / II 2D Ex h IIIC T180°C Db – approved for Ex-zones 1/2 and 21/22.
- SIL 3: Safety Integrity Level 3 per IEC EN 61508.
Pneumatic or Electric Automation
- Pneumatic flanged ball valve: double-acting or spring-return (Fail-Close / Fail-Open)
- Electric flanged ball valve: J4C rotary actuator 24V, 230V or 400V AC/DC
- Worm gear with handwheel for larger sizes
- Hand lever (standard)
Accessories: limit switch box, Namur solenoid valve, positioner and stem extension – delivered assembled on request.
