Ductile iron Resilent Seated Water Gate Valve Fusion Bonded Epoxy Coated
Forming Machine Process
1. CNC Lathe Processing
2. High precision CNC machining center processing
3. General lathe processing
4. The machine punch the product parts
5. Cold Forming Molding
6. Welding Assembly
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. WRAS Approved EPDM fully vulcanized
2. Suitable rubber hardness for long lasting
• 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.
• Forged stem provide stronger stem operation and less moving parts.
1. Customized Material, like SS420 / SS431 / SS304/ SS316 are available.
2. Platform on the stem provide better strength. Pass R-key test.
3. High-tech rubber curing with precise geometry dimensions, more resilient & strong adhesive to ductile casting.
• Epoxy powder coated with minumum thickenss 250um.
• Wter Gate Valve 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.
