Product benefits
- High tightness: The spring-loaded seat rings achieve precise tightness in the seal, the torques remain constant with different media, pressures and temperatures.
- TA-Luft certified: The stem offers a high level of tightness to the outside and is TA-Luft certified. Furthermore, the housing is manufactured as a one-piece design (no housing split). This prevents further leakage to the outside.
- Blow-out-proof switching shaft: inserted from the inside, highly polished ball surface and extremely accurate contours (roundness)
- High switching frequency: due to the spring-loaded switching shaft seal
Externally tested functional reliability
- Firesafe approval and antistatic device in accordance with BS 6755 Part 2
- CE-compliant in accordance with PED 97/23/EC
- Tightness in accordance with DIN EN 12266-1
- ATEX Directive 94/9/EC is fulfilled
