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. 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.
