F4 Resilient Seated Gate Valves-TT Type
GV-Resilient seated gate valve is a soft seal
disc which is fully encapsulated with 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, fi re-fi ghting and
function as a shut-off or regulating Valve.
Features:
• Newly advanced design, less operation torgue &
abrasion resistance.
• Body & Cover are made of high grade Ductile Iron.
• Disc is designed with an abrasion resistant nylon
guide which can help less open 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
complies with drinking water.
• High-tech rubber curing with precise geometry
dimensions, more resilient & strong adhesive to
ductile casting.
• The 3 O-ring stem seals are designed to prevent
stem leakage. and provide replacement of the
other 2 O-ring without disassamble of valve from
mainline pipes.
• Both inside & outside are coated with epoxy resin
powder.
• Manufacturing standard meets BS EN ***4, BS
***3, DIN ***2.
• F/F (Face to Face) meets the following standard:
BS EN****1, DIN ***2.GB: ******9
