CBF02-TF01-Operation and Maintenance Manual DOWNLOAD
All major parameters of this valve are customizable to meet specific project requirements:
Body material: Ductile iron (GGG40) is offered as a standard option, with an epoxy coating applied for external corrosion protection. The coating color is customer-selectable – any RAL or custom color can be specified. Alternative body materials such as carbon steel (WCB), stainless steel (CF8, CF8M), or other alloys are also available upon request.
Disc material: Super duplex (5A) as described; other disc materials can be supplied if specified.
Seat elastomer: EPDM, NBR, or Viton – customer choice.
Pressure rating: No fixed default – each order is manufactured to the required rating, such as PN10, PN16, PN25, Class 150, Class 300, or others.
Flange standard: Conforms to customer specifications (e.g., EN 1092, ANSI B16.5, AS2129, etc.).
Size range: 18 inches (DN450) as described; other sizes from DN50 up to DN2000 are also available.
Double flanged body: Provides a rigid, bolted connection on both pipeline sides, offering excellent mechanical stability for permanent installations, high-vibration lines, and dead-end service.
Vulcanized rubber seat: The elastomer is permanently bonded to the body during vulcanization, creating a leak-proof seal without removable components.
ISO 5211 top flange: The valve's upper flange is machined to ISO 5211 standards, allowing direct mounting of electric, pneumatic, or hydraulic actuators without custom adapters, simplifying automation integration.
