COVNA Valves For Industrial Fogging Systems

Fogging system is to achieve atomization of liquid, which can be used in fire fighting industry, dust-free treatment equipment, mosquito repellent fogging equipment and other automated industries and equipment. Valves assist in the transfer of liquids to the fogging system and increase productivity. The process of atomizing liquids requires high pressure, so we would recommend the use of high-pressure valves for atomization systems.
In this article, we will introduce you to the COVNA high-pressure valve series, which we hope will help to understand and select the right valve.

High-pressure Ball Valves

The body thickness of the high-pressure ball valve is 2 times thicker than that of a normal ball valve. When subjected to the impact of high-pressure media, it can still maintain stability and normal operation. The thicker body keeps it from blowing up, thus ensuring the proper operation of the project. The high-pressure ball valve can withstand pressures up to 400 bar, so it will be your valve of choice.
The high-pressure ball valve can be driven by electric or pneumatic actuators, thus enabling remote control of the valve.

High-pressure Butterfly Valves

High-pressure butterfly valves are generally referred to as triple eccentric hard seal butterfly valves. It can withstand pressures of up to 40 bar. The size range is up to 16″, which makes up for the lack of ball valves (the maximum size of high-pressure ball valves is only 2″). The high-pressure butterfly valve is available with a choice of clamped and flanged connections.
Likewise, the high-pressure butterfly valve can be driven by electric actuator or pneumatic actuator.

Above is the introduction of high-pressure valves that can be used in atomization systems. If you have any need for valves, welcome to consult us for the best valve solution and budget cost.


COVNA Valves For Automatic Backwash Filters

The automatic backwash filter is fully automatic filter equipment. It can be used for water supply systems in metallurgy, chemical, petroleum, paper, food, mining and other industries. The valve can assist the automatic backwash filter to transport waste water or purified water to improve production efficiency. In this article, we will introduce you to the valves that can be used for automatic backwashing filters, and hope to help you understand and choose the right valve.

Butterfly Valve

Butterfly valve is a commonly used valve. Its advantages include easy installation, easy operation, and the material of the valve plate or seal can be changed according to the needs of your project to meet the needs of various pipelines. According to the type of connection method, butterfly valves can be divided into wafer butterfly valves, flanged butterfly valves, lug butterfly valves, etc., making your installation easier. According to the difference of seals, butterfly valves can be divided into soft-sealed butterfly valves and hard-sealed butterfly valves to meet the needs of various media. Therefore, butterfly valves can be used on various types of pipelines and can help you to circulate, block and regulate flow.

Butterfly valve can be equipped with electric actuator, pneumatic actuator, handle or turbine drive to help you realize industrial automation.

Ball Valve

The ball valve is a 1/4 turn valve. The ball rotates 90 degrees with the stem, which opens or closes the valve. Ball valve is also a commonly used valve. It can be used in industries that require high temperature, high pressure or corrosion protection. According to the difference of the flow direction, the ball valve can be divided into two-way ball valve, three-way ball valve or four-way ball valve, which can help you divide, merge and change the flow direction of fluid.

Similarly, ball valves can be driven by electric actuators, pneumatic actuators, handles or turbines to meet your remote or on-site valve control needs.

In addition, gate valves, check valves, globe valves, and Y-strainers are also used in automatic backwash filters. If you have any needs for valves, please consult us for the best valve solution.

5 Types Of COVNA Industrial Valves

In this article, we will introduce the 5 types of industrial valves for your reference. And hope this article could help you to know and select the right valve for your project.

Ball Valve

The ball valve is one of the quarter-turn valves, which can be opened or closed only by turning 90 degrees rotations. It is mainly used for start, shut-off and regulate the flow rate of fluid.

Features Of Ball Valves
Easy to operate and easy to repair
A variety of designs, applied in different industries
A variety of materials can meet your media requirements

Disadvantages Of Ball Valve
The size range is small, and the large-size ball valve is costly

Ball valves are suitable for smaller pipes. Mainly used for low pressure applications, if you need to use in high temperature or high pressure industries, you may need to customize the ball valve for your applications

Butterfly Valve

The butterfly valve is the same as the ball valve, it only needs to turn a quarter turn to open or close. When the valve is opened, the disc and the medium remain parallel. When the valve is closed, the disc and the medium remain vertical.

Features Of Butterfly Valves
Compact design, saving installation space
Easy to install
Large size range for various pipeline

Disadvantage Of Butterfly Valves
Not suitable for high pressure applications unless use the hard seat butterfly valve, but its cost is higher

Butterfly valves are very suitable for large-size pipelines, such as wastewater treatment, power plants, etc.

Check Valve

Check valve is a valve that can be opened and closed by relying on internal pressure. It is mainly used to prevent backflow and protect project safety.

Features Of Check Valves
Simple design and easy to operated
Multiple materials to meet your requirements of mediums
Disadvantage Of Check Valves
Not suitable for start, shut-off or regulating.

Gate Valves

The gate valve is mainly used to circulate and cut off the medium. Since it can only be fully open and fully closed, the flow cannot be adjusted.

Features Of Gate Valves
Can be used for two-way circulation
easy to use
Suitable for large size pipes

Disadvantage Of Gate Valves
Not able to regulate the flow rate

Globe Valves

The globe valve is similar to the gate valve in that the valve stem does linear movement to open or close the valve. The difference is that the stop valve can be used to circulate, cut off, and adjust the flow.

Features Of Globe Valves
Able to help to regulate the flow rate
Easy to install and easy to operate

Disadvantages Of Globe Valves
Not suitable for high pressure applications

The above are the 5 industrial valves provided by COVNA. Hope to help you understand and choose the valve, and better apply it in your project.
