The difference between pneumatic high platform ball valve and ordinary

Author:


Pneumatic ball valves are one of the most widely used types of valves in recent years. They are not only easy to operate, but also perform very quickly. They are used in many fields, such as petroleum, chemical industry, power generation, papermaking, food, pharmaceutical industries and other sectors. and in people’s daily lives. By connecting the air source, solenoid valve control, and related accessories, the pipeline can be quickly opened or closed, and intelligent control can be performed to adjust various process parameters such as pipeline media!

There are many types of pneumatic ball valves, which can be divided into various models according to pressure, material, connection form, application medium, including control form. Today we will analyze the differences and choices between pneumatic high platform ball valves and ordinary pneumatic ball valves with brackets!

 

Pneumatic high platform ball valve description and advantages and disadvantages:

Pneumatic high-platform ball valves, as the name suggests, are ball valves designed with a high platform, commonly used in ISO standards. The purpose of this is to facilitate the installation of the drive device with a connecting plate that can be directly installed and connected to the (electric/pneumatic) actuator without the need for a bracket. and connecting shaft. It can save costs by eliminating the need for brackets, improve production efficiency, and greatly improve the stability between the valve and actuator. The performance is also very stable during use, and the suitability of the overall valve will not be affected by loose brackets or large coupling gaps.

The advantage of pneumatic high platform ball valve is that it is more beautiful, more refined and elegant in appearance than ordinary ball valves, takes up less space, and has a more compact structure. The disadvantage is that it is not resistant to high temperatures. The temperature is transmitted to the cylinder and the rubber ring in the cylinder is easy to age. It is generally applicable In pipes where the medium temperature is below 80 degrees.

 

Description, advantages and disadvantages of pneumatic ball valve with bracket:

The use and functions of pneumatic ball valves with brackets and high-platform ball valves are the same. The difference is that there is a bracket between the actuator of pneumatic bracket ball valves and the ball valve body. Usually, a bracket is required if the medium temperature is high. , this can avoid damage to the actuator due to high temperature. Generally speaking, the ultimate purpose of having a bracket is to extend the service life of the valve.

 

The advantage of the pneumatic ball valve with a bracket is that its heat dissipation function is relatively strong. For example, if the medium temperature of the pipeline is above 300 degrees, then at this time, it is recommended that the valve stem of the pneumatic ball valve should be lengthened accordingly and it should also have a bracket. The reason why the valve stem is extended with a bracket is to separate the ball valve body and actuator to prevent the medium temperature of the ball valve body from being too high, which will affect the service life of the actuator. For example, when the valve body of a ball valve is soaked in a liquid medium, and the liquid medium is highly corrosive and cannot be approached by operators, and the actuator is outside the liquid surface, the actuator needs to be operated by staff. In this case You need to choose a ball valve with an extended stem and a bracket. If the liquid is highly corrosive, the ball valve must be made of standard stainless steel to ensure the normal operation of the pneumatic ball valve.
