resilient seated gate valve

Resilent Seated Gate Valve, Ductile iron, Epoxy Coated, Outside Screw And Yoke, Non Rising Stem 
 
 
 

Surface Treatment

We offer the following processes to choose:

1. Mechanical Polishing (MP) to improve brightness (gloss, matte)

2. Acid Cleaning for Anti-corrosion

3. Electrolysis Polish (EP) to improve surface smoothness

4. Custom Process: Bright Annealing treatment eliminate strees to improve toughness

 
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, fire-fighting and function as a shut-off or regulating valve
 
Newly advanced design, less operation torgue & abrasion resistance.
 
Features:
 
•  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.
   1. EPDM fully vulcanized
   2. WRAS approved 
•  Forged stem provide stronger stem operation and less moving parts.
   1. SS420 / 431
   2. Platform provide better strength
•  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 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.
