Gate Valve
Cast Iron Gate Valve, Specification for Gate Valves: 1. Brief Introduction: The cast iron gate valve, normally with brass trim, is ideally suited for cost effective sewage piping and water treatment pipeline which are very common in the utility projects. 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 Gate Valve, DESCRIPTION: ZENO supplies diverse Cast Steel Gate Valves. The cast steel mainly refers to the bonnet and body of the gate valve. It includes carbon steel(WCB, LCB, WCC) and stainless steel(CF3, CF3M, CF8, CF8M). Full SPECIFICATION of Cast Steel Gate Valves: 1. Brief Definition: The gate valve is a linear-motion valve that uses a typically flat closure element perpendicular to the process flow, which slides into the flow stream to provide shutoff. It can be applied to both liquid and gas services for on-off function. Normally it can be sorted as per parallel type and wedge type. Parallel gate valves are slide valves with a parellel-faced gate-like closure member while wedge gate valves are with wedge-shaped gate like closure member. 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 Wedge: WCB, LCB, 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: 1/2" ~ 48" (DN15 ~ DN1200); 150LB ~ 2500LB 4. Standards: API 6D, ANSI B16.34, API600, API603, BS1414 5. CZENOtruction Structure: Full Port/Reduced Port, Bolted Bonnet/Pressure Seal Bonnet, Wedge/Parallel, Flexible/Solid Disc Renewable Seat Ring/Fixed Seat Ring, Rising Stem/Non-Rising Stem, Outside Screw & Yoke(O.S&Y)
Forged Steel Gate Valve, Full SPECIFICATION of Forged Steel Gate Valves: 1. Brief Definition: Forged steel gate valves usually have rising stem structure 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 gate 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 Seat Ring: AISI 410, 410+HF, SS 304/304L, SS 316/316L, F51 Wedge: F6a, F6a+HF, F304(L), F316(L) 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" ~ 2-1/2" (DN15 ~ DN65); 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)
