CONSTRUCTIONAL FEATURES
- Full, smooth, even and cavity-free passage.
- Connections with internal and internal-external threads.
- The valve stem sealing may be replaced under full pressure in any position of the wedge.
- A brass screw of the gate valve stem seal (replaceable) protected against unscrewing by a stainless steel spring ring, located inside the cover under the top seal.
- Stainless steel non-lifting stem with cold rolled thread, with no notches in the sealing zone, making it possible to work with o-rings in the screw.
- Triple sealing system of the stem: top seal, set of 5 o-rings (4 o-rings inside and outside the screw), bottom seal, lip seal.
- Bottom washer made of polyamide PA6, which is a sliding washer to secure the low-friction bearing of the spindle.
- Body and cover made of ductile cast iron grade EN-GJS 500-7.
- Wedge made of ductile cast iron (for DN25 and DN32 made of brass) vulcanized inside and outside with EPDM or NBR rubber with a hardness of 70±5°Sh. Guided in guides being an integral part of the gate body.
- The thickness of the rubber on the wedge is at least 3mm.
- Wedge suspension nut on the stem – non-replaceable, made of brass, hot-dipped in the wedge of the gate valve.
- Static seals made of EPDM rubber, dynamic seals made of NBR rubber.
- Screws connecting the cover with the body – blind threads, fully protected against corrosion with paraffin-wax compound.
- Internal and external corrosion protection with RAL 5015 epoxy powder paint with a minimum thickness of 250μm and a breakdown resistance of 3kV.
