Product Description:

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

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.

Q:Does the tap belong to a stop valve or a gate valve?
Most faucets are stop valves,Part of the faucet is plug valve,Hot water nozzles are almost all plug valves.
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
Q:Is the axial force and torque of the wedge gate valve the same?
B higher temperature. C nice wedge single gate valve is suitable for high temperature medium easy to coking. Flexible gate valve features: high temperature, a wedge type single gate valve in a special form. Comparison with wedge gate valve.
Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
Gate valve code Z, such as GB gate valve Z41H-16. Front is the valve type, and the back 16 represents the pressure of 16 kg, 1.6MPa
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: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 are the standards for the execution of cast iron dark pole gate valves?
They are also standard in the production of cast iron dark rod gate valves:Design and manufacture: as per GB/T12234-89 regulationsLength of structure: as specified by GB/T12221-89Flange dimensions: as specified in JB79 GB/T9112-9131Inspection and test: as specified in JB/T9092-99 GB/T13927-92Drive mode: manual, electric, gear drive
Q:What are the features and uses of the gate valve?
What is gate valve? What is the purpose of forged steel gate valves? What are the features of forged steel gate valves?Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate valve movement direction perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angles vary with valve parameters. Gate valve drive classification: manual gate valve, pneumatic gate valve, electric gate valve.DefinitionGate valve means the closing of the valve (gate) along the central line of the vertical direction of the valve. The gate valve is mainly used for cutting in the pipeline.The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is betterValve also has shortcomings:The overall size and opening height are larger. Larger space required for installation.In the process of opening and closing, there is relative friction between the sealing surfaces, which may cause galling.Gate valve generally has two sealing surface, processing, grinding and maintenance to increase some difficulties.
Q:What's the meaning of the gate valve model z41x 16Q?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = flange connection1 = structural form: wedge type single gateX = sealing surface material: Rubber16== pressure rating: 1.6MPaQ== body material: ductile iron
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.
