Gate Valve
Flange ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between class150-2500, working temperature≤600°C, in oil industry, chemical industry, fossil-field power plants.
Design Feature of Gate Valve
1. Both design and manufacture are carry out strictly fellow API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2. Co hard alloy welded sealing surface, which is wearing resistance, erosion proof, abrasion proof and long-lived.
3. The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistance.4. Class≥900LB, the media cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.
5. There is backward sealing structure in the valve, so the sealing is reliable.
6. The material of the filling and the flange size can be chosen and the matched according to the applications and the requirement of the wier's. That can satisfy all kinds of working requirements.

The package of gate valves
- Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?
- Steam traps: in steam, compressed air and other media, there will be some condensation water formation, in order to ensure the efficiency and safety of the device operation, should be timely discharge of these useless and harmful to the media, to ensure the consumption and use of the device. It has the following functions: 1. It can quickly eliminate the condensed water; prevent leakage of steam; remove air and other non condensable gases.Pressure reducing valve: by adjusting the inlet pressure to a certain outlet pressure, and rely on the energy of the medium itself, so that the outlet pressure automatically maintain a stable valve.Check valve: also known as reverse flow valve, check valve, back pressure valve and one-way valve. The valves are automatically driven and closed by the flow of the medium itself, belonging to an automatic valve. The check valve is used for piping system, the main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. It can be divided into swing type (rotating by gravity center) and lifting type (moving along the axis).
- Q: What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
- Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
- Q: Valve flange drawing n- up to what
- A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
- Q: Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
- In the standard JB/T5296-1991 "universal valve flow coefficient and the flow resistance coefficient test method",
- Q: Z41T one 10 gate valve and Z44T one, 10 gate valve difference
- Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
- Q: What is the meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?
- Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.
- Q: What are the structural differences between parallel and wedge valves?
- The double gate is pushed aside so that the sealing surface of the valve gate is tightly sealed with the valve body. These double gate parallel gates are mostly used on low pressure pipelines such as small pipelines. Parallel gate valves are also available with single gates, but are rare.That the sealing surface has a certain angle with the vertical center line, bearing higher medium temperature valve, angle the greater the possibility to reduce the temperature when wedged gate rice.Wedge gate valve single, double all.
- Q: What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?
- 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: for electric, flange connections, Ming Liang wedge double gate, the sealing surface material directly processed by the body, nominal pressure PN0.1MPa body material for gray cast iron gate valve: Z942W-1 electric wedge double gate valve
- Q: What is the difference between gate valve and gate valve? Is it the same valve?
- Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.
- Q: Which is the most expensive, check valve and gate valve?
- In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124
