Combi-T gate valve "E3" - BAIO® system for gas

"Product: Hawle type E3 (Ord. No. 437-00G) or equivalent
Pipe fitting with resilient-seated gate valve in lateral outlet, with equal or reduced outlet, with BAIO double function sockets at all ends to establish form-locked connections with BAIO spigot ends and for connecting CI, steel, PE and PVC pipes.
Wedge and wedge nut fully coated with vulcanized elastomer. The wedge is connected to the wedge nut with a flexible link and embedded in elastomer. This snug fit dampens vibration during opening and closing of the wedge. Wedge nut thread length ≥ 1,2 x spindle diameter. Wedge guide of wear-free plastic with good sliding properties ensures low wear and minimum closing torques. Spindle with rolled thread and polished in the area of the O-ring sealing. Maintenance-free spindle sealing by 5-fold O-ring sealing. O-ring carrier connected corrosion-resistant to the fully coated bonnet by a double bayonet connection.
Low-friction bearing of the spindle on sliding disks of POM on both sides.
Extended edge protection of PE protects valve during storage and transportation.
Round thread connection at the bonnet for pinless fixing of Hawle extension spindle
Test regulations: EN 1074-1, EN 1074-2 and EN 12266-1
