Flanged gate valve, NRS, UL/FM approved for fire protection applications to max. 70°C and 250 psi
AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized with AVK’s own drinking water approved EPDM rubber compound. It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The triple stem seal system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.
| Variant 145/50-005 | |
|---|---|
| Connection: | Flanged |
| Material: | Ductile iron |
| DN: | DN65 - DN200 |
| PN: | PN 16 |
| Closing direction: | Clockwise to Close |
Features
- Wedge core in ductile iron, fully encapsulated in drinking water approved EPDM in a 2-step vulcanization process that leaves a very strong rubber-iron bond preventing corrosion underneath the rubber. No iron parts are exposed to the water
- Fixed, integral wedge nut prevents vibration
- Wedge shoes integrated in the rubber gives low operating torque
- A large through bore in the wedge eliminates collection of stagnant water
- Stem of stainless steel 304
- O-ring as main stem seal with back up from two O-rings surrounding the polyamide radial bearing, replaceable under operating pressure
- Round bonnet gasket, fixed in a groove in the bonnet preventing it from being blown out in pressure surges
- Counterbored and hot melt sealed A4 stainless steel bonnet bolts encircled by the bonnet gasket to prevent contact with the water
- Full bore and clear way
- Lightweight flange design (DN80 and 200 full flange)
- Epoxy coating acc. to DIN 3476, red RAL 3000
