Globe Valve
Globe Valve
Cast Iron Globe Valve, Specification of Cast Iron Globe Valves: 1. Brief Introduction: The globe valve is a closing-down valve in which the closure member(often called disc) is moved squarely on and off the seat. By this mode of disc tavel, the seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. 2. Material Specification: Body & Bonnet: Cast Iron or Ductile Iron Wedge: Ductile Iron, or Ductile Iron coated with brass Stem: Carbon Steel, Stainless Steel or Bronze Wheel: Cast Iron, Ductile Iron Yoke Nut: Ductile Iron or Bronze 3. Sizes and Pressure Ratings: 2" ~ 12" (DN50 ~ DN300) PN6, PN10, PN16; 5K, 10K, 16K 4. Standards: DIN, BS, JIS, ANSI
Cast Steel Globe Valve, DESCRIPTION: ONS supplies Cast Steel Globe Valves. The "cast steel" refers to the material specification of valve body and bonnet of the globe valve. Our casting covers a wide range of carbon stee, stainless steel, alloy steel and aluminium bronze, etc. Specification of Cast Steel Globe Valve: 1. Brief Introduction: The globe valve is a closing-down valve in which the closure member(often called disc) is moved squarely on and off the seat. By this mode of disc tavel, the seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. 2. Material Specification: Body & Bonnet : WCB, LCB, WC1, WC9, C5, C12, CF8, CF8M, CF3, CF3M, Aluminium Bronze Seat Ring: A105, LF2, F304, F316, F304L, F316L, F51, Aluminium Bronze Disc: A105, LF2, WC1, WC9, CF8, CF8M, CF3, CF3M, Aluminium Bronze Stem & Gland: F6, F304, F316, F51, F304L, F316L; Bolts & Nus: B7/2H B8M/8M Handwheel: Cast Iron, Carbon Steel, Stainless Steel 3. Size and Pressure Ratings: 2" ~ 36" (DN15 ~ DN900); 150LB ~ 2500LB 4. Standards: BS1873, ASME B16.34, ASME B16.5, ASME B16.47, ASME B16.25, ASME B16.10, MSS SP25 5. Construction Structure: Full Port/Reduced Port, Bolted Bonnet/Pressure Seal Bonnet, Flexible/Solid Disc Renewable Seat Ring/Fixed Seat Ring, Rising Stem/Non-Rising Stem, Outside Screw & Yoke(O.S&Y)
Forged Steel Globe Valve, Full SPECIFICATION of Forged Steel Globe Valves: 1. Brief Definition: The forged steel globe valve usually has a rising stem with one-piece body. The position of th stem helps in identifying whether the valve is in closed or open position. Since the forgings have perfect mechanical and chemical properties in comparison with castings, the forged globe valve is mainly used in high pressure and high temperature services covering a small size range. 2. Material Specification: Body & Bonnet : A105, LF2, F11, F22, F304/F304L, F316/F316L, F51 Disc: F6a, F6a+HF, F304(L), F316(L), F22, F51 Stem & Gland: AISI 410, F304(L), F316(L), F51; Bolts & Nus: B7/2H B8M/8M Handwheel: ASTM A197, Packing: Flexible Graphite 3. Size and Pressure Ratings: 1/2" ~ 4" (DN15 ~ DN100); 150LB ~ 1500LB 4. Standards: API 602, BS5352, ASME B16.34, ASME B16.25, ASME B16.11, MSS SP25, ASME B16.5, ASME B1.20.1 5. End Connection: Socket Weld(SW), Threaded, Flanged, Butt Weld(BW)
