1. How does a gate valve work?

Gate valve is a common type of valves, which works on the following principle:

The disc of the gate valve is perpendicular to the direction of the fluid flow. When the gate valve is in the open state, the disc rises, so that the fluid can pass through the valve channel without obstruction. The lifting height of the disc is equal to the diameter of the valve, providing an almost unobstructed fluid passage, so the fluid resistance of the gate valve is very low when fully opened.

In the closed state, the disc descends vertically along the center line of the valve seat, tightly pressing against the valve seat to form a seal and prevent fluid from passing through.

The movement of the disc is usually operated through the valve stem. The valve stem connects the disc and external operating mechanism, such as handwheel, electric actuator, or pneumatic actuator.

The sealing performance of the gate valve mainly depends on the fit between the gate disc and the valve seat. High quality gate valves are designed and manufactured with full consideration of factors such as the selection of sealing materials and processing accuracy to ensure good sealing performance under various working conditions.

Taloar's gate valves have the advantages of simple structure, low flow resistance, reliable sealing, and easy operation, and are widely used in pipeline systems in industrial fields such as petroleum, chemical, power, and metallurgy.

2. What are the factors to consider when choosing a gate valve?

●The first is the working pressure and temperature, which are directly related to the material and sealing performance of the gate valve. High pressure or extreme temperature require better quality materials and more reliable sealing.

●The nature of the fluid can not be ignored, such as whether the fluid is a gas or a liquid, whether it is corrosive, flammable, and the viscosity, etc., so as to determine the gate valve material and sealing material can be adapted to it.

●Flow requirements are also crucial. Gate valves with appropriate diameters can ensure smooth fluid flow and avoid unnecessary pressure losses.

●Sealing performance is an important indicator for preventing leakage. The quality of sealing materials and the precision of sealing surface processing should be examined.

●The selection of operation mode should be based on actual needs. Manual operation is suitable for small and simple systems, while electric, pneumatic or hydraulic operation is more suitable for large, complex or highly automated systems.

●Installation space and size limitations should also be considered to ensure that the gate valve can be installed in place and operated normally.

In addition, gate valves should comply with relevant industry standards and specifications to ensure quality and safety.

3. What are the applications of gate valves?

Gate valves have a wide range of applications in various fields. Here are some of the common application scenarios:

In the petrochemical industry, gate valves are commonly used in pipeline systems to control the transportation of crude oil, refined oil, various chemical raw materials, and products. For example, in oil pipelines in refineries, and in material transportation pipelines in chemical plants, etc.

In the power industry, gate valves can be used in steam pipelines, water pipelines, etc., to control the flow of steam and water, ensuring the normal operation of power generation equipment.

In urban water supply and sewage treatment systems, gate valves are used to regulate the direction and flow of water, control the distribution and treatment of water.

In the metallurgical industry, gate valves are commonly used in pipelines for high temperature, high pressure, and corrosive medium, such as gas pipelines and cooling water pipelines in steel plants.

In the construction industry, gate valves can be used in pipelines of HVAC systems, fire protection systems, etc. to control the medium.

In the shipbuilding industry, gate valves play an important role in various liquid and gas pipelines, ensuring the stable operation of ship systems.

In short, gate valves have been widely used in pipeline systems in many industrial and civilian fields due to their reliable performance and good sealing performance. Taloar's users and markets cover various commercial, residential, and industrial facilities. Including fields such as petroleum, petrochemicals, natural gas pipelines, refineries, firefighting, construction, power plants, water treatment, shipbuilding, etc.
