Resilent Seated Gate Valve, Ductile iron, Non Rising Stem  EPDM/NBR Wedge Available

Decription:

Resilient seated gate valve is a soft seal disc which is fully encapsulated with EPDM or NBR rubber. The valve is designed with new technology for light operating, no clogging and no corrosion, good resilient memory & long service life. It can be used extensively in all kinds of water supply & sewage, fire-fighting and function as a shut-off or regulating valve.

Features:

• Newly advanced design, less operation torgue & abrasion resistance.

•  Body & bonnet are made of high grade ductile Iron GJS500-7

   
•  Disc is designed with an abrasion resistant nylon guide which can help less opening or closing torgue and smooth during operation.

•  Forged stem provide stronger stem operation and less moving parts.

•  Disc is covered by high-grade rubber which meet drinking water standard.

•  High-tech rubber curing with precise geometry dimensions, more resilient & strong adhesive to ductile casting.

•  The 4 O-ring stem seals are designed to prevent stem leakage. and provide replacement of the O-ring without disassambling of valve from mainline pipes.

•  Both inside & outside are coated with epoxy resin powder.

•  Manufacturing standard meets BS EN 1074-1, EN1074-2, BS 5163, BS EN 1171.

•  F/F (Face to Face) meets the following standard: BS EN558-1.

•  Bolts are protected by silicon glue.
