Insulation Flat Gate Valve

Price: The price is changing because of material cost and exchange rate. Please give me your contact information, I will update the newest price to you.

1. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

2. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

3. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

4. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

Q: What is an insulated gate valve?

A: Jacket insulation gate valve is mainly used in chemical, petroleum, pharmaceutical, metallurgy and other industries in the system pipeline, the main role is to transport at room temperature will solidify, easy to crystallize the medium. A metal jacket is soldered between the flange of the thermal insulation gate valve, and a jacket interface is provided on the side and bottom of the ordinary gate valve for injecting steam or other thermal insulation and cold media to ensure that the medium in the valve can work normally. The connection flange of the insulation gate valve is larger than that of the ordinary stop valve to two specifications.

Q: What is the purpose of the insulation gate valve?

A: The thermal insulation gate valve has been widely used in various systems such as petroleum, chemical, gold, pharmaceutical, etc., effectively reducing the heat loss of the medium in the pipeline and preventing the appearance of crystallization and solidification of the medium. The function of the thermal insulation gate valve is that when the temperature is high or low, the material in the thermal insulation gate valve has a thermal insulation effect on the medium, so that the medium will not condense or stick inside the valve body, so that the opening and closing of the valve can operate normally.

Q: What are the requirements for valve packing?

A: The valve requirements for packing, there are four main points :① corrosion resistance; ② Good sealing; ③ Small friction coefficient; ④ Small corrosion (graphite filler must be corrosion inhibitor for corrosion protection).

Q: What material is suitable for valve stem nuts?

A: Because the valve stem nut is directly subjected to the axial force of the valve stem during the valve opening and closing process, it must have sufficient strength; At the same time, it is threaded with the valve stem, requiring a small coefficient of friction, no rust and avoid biting phenomenon. Therefore, copper alloy material is the most suitable for the valve stem nut. Because the friction coefficient of copper alloy material is small and does not rust, it is one of the commonly used valve stem nut materials.
