  • Full, smooth and cavity-free passage.
  • 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 protecting low-friction bearing of the spindle.
  • Body and cover made of ductile cast iron EN-GJS 500-7 or grey cast iron EN-GJL 250.
  • Wedge made of ductile cast iron, vulcanised inside and outside with EPDM or NBR rubber, hardness 70±5°Sh. guided in guides being an integral part of the gate body.
  • Wedge suspension nut on the stem – non-replaceable, made of brass, hot-dipped in the gate valve wedge, eliminating the possibility of wedge vibration.
  • 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 protection against corrosion with epoxy powder paint RAL 5005, thickness min. 250um and puncture resistance 3kV
