BLS GATE VALVE SCREWLESS
READY FOR ZEROWATERLOSS
Optimized for underground installation
The BLS gate valve complements the BLS push-in sleeve system and combines the proven technical properties for the benefit of the user.
Thanks to the screwless, tension-resistant push-in socket connection and the screwless connection of the gate valve body as well as the high level of corrosion protection, the system is optimized for underground installation and ensures a long service life.
- Longitudinal force-secured and form-fit socket connection
- Can be angled up to 5° (with a high safety factor in the event of an accident)
- Screwless connection between gate valve housing and gate valve cover
- Fast and cost-effective installation
- Screw-on adapter for VR extension spindle - no pinning and vertical fixing in the pipe trench
- Fully vulcanized wedge with vulcanized sliding shoes, guarantees at least 2500 load cycles (DIN EN 1074-2)
- Lower actuating forces than prescribed by standardization
- Stem seal - dead space-free design with triple O-ring seal
- High-quality corrosion protection - epoxy powder coating Full protection - GSK certified
(GSK community heavy corrosion protection) or by high-quality enameling according to DIN EN ISO 11 177
