CONSTRUCTIONAL FEATURES

• Full, smooth, even 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 to secure the 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, vulcanized 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 corrosion protection with RAL 5005 epoxy powder paint with a minimum thickness of 250 um and a breakdown resistance of 3 kV
