All ball valves are full ported and meet the design requirements of American petroleum institute standard API 608 & API 6D, British standard BS 5351 and generally conform to American society of mechanical engineers standard ASME B16.34. Valves are available in a complete range of body/ bonnet materials and trims. Trim changes End connection modifications Packing and gasket changes Operator mounting Flandwheel extensions (©Body & bonnet Split or 3-piece, split body & bonnet for 8" & small. Disassembles easily for repair or replacement of internal components. Rang of Materials Standard body/bonnet materials include nine grades of carbon, low alloy and stainless steels, For special applications they can be supplied in other grades of alloy and stainless steel. There's a full range of trim materials to match any service. Optional packing and gasket materials are available for a full range of service conditions. Pressure equlizing AS or FD Customer specified coatings Weld end bore changes Oxygen & chlorine cleaning & packaging ®AS Anti static. A metallic contact is always granted between ball and stem/body to discharge eventual statics build-op during service. ©Grease-Jet joint Installed in prescriptive part accord with the apply and satisfied with ecumenical situations and realize seal in spot with maintenance easily. ©Packing STD Packing adopt high-performance rubber seal ring, STD Packing and TEFLON use situation for smooth pressure. With spring apply high-pressur-esituation. Graphite packing use situation for high-temperature. ©FD Fire durable. Designed to API 607 or BS 6755 to grant their operation suitability in case of fire. Secondary metal-to-metal seal acts as backup if primary seal is destroyed by fire. Valves ordered for compliance with API 607 will be provided with graphite packing and gaskets. ©DDB Double block & bleed. The body cavity is isolated when the ball is in either fully closed or fully opened position, the medium entrapped in it can easily be bled to avoid over pressure. ©BORE Full bore or reduced bore. Full-bore design provides exceptional flow control. ©GASKET Adopt high-performance rubber seal ring and spiral wound graphite.
