What Is Pneumatic Accessories?

Pneumatic accessories are industrial equipment used to realize industrial automation. There are positioners, limit switches, pneumatic reversing valves, air filters, etc. for your choice. Each pneumatic accessory has a different function. It is generally used with various types of pneumatic valves, which is convenient for remote control and industrial automation to improve the production efficiency […]

COVNA Actuator Valves For Mechanical Vapor Recompression

Mechanical vapor recompression is an industrial system for seawater desalination, metal processing plants, and food processing plants. It is used for waste & wastewater treatment, improving water resource utilization and waste treatment rate, and making our living environment more environmentally friendly. Since 2000, COVNA helped more than 500 wastewater treatment projects with automated valve solutions. […]

COVNA Actuator Valves For Industrial Tunnel Washers

Industrial tunnel washers provide large-scale and environmentally friendly commercial washing services. Able to use less water, and wash more cleanly. Valves play a role in conveying water or detergent in industrial tunnel washers. Helping industrial tunnel cleaners run smoothly and improve efficiency. Below, we will introduce you to the valves that can be used in […]

Why Choose Pneumatic Sanitary Valves?

Pneumatic sanitary valves are electronically polished as standard, and the smooth surface ensures cleanliness with no areas of media accumulation and potential contamination. Other valves are generally modeled according to the needs of use, mainly in the high temperature and high pressure working environment, long service life and flexible operation mode. Materials Sanitary valves can […]

COVNA Actuator Valves for Marine

The marine valve is a device used to control the pressure, flow and flow direction of the fluid in the ship’s pipeline to meet the environmental conditions of the ship. The marine valve is a control device for the fluid pipeline. Its basic function is to connect or cut off the flow of the medium […]

What is COVNA Pneumatic Control Valve?

Pneumatic control valves are mainly used in transportation systems in medical, food, petroleum, natural gas, water treatment, and other industries, and are suitable for controlling gas, steam, liquid, and other media. Compared with other general pneumatic actuator valves, it adds some control components, and the whole is more complicated, so the required debugging process is […]

What Is COVNA Pneumatic Knife Gate Valve?

Pneumatic knife gate valve is a relatively complex automatic control, which is composed of a variety of pneumatic components and valve bodies. It is suitable for medium pipelines such as syrup, paper pulp, sewage, coal slurry, ash, dust, and slag-water mixture. In the past, such as in paper industry applications, viscous pulp can get stuck […]

Pneumatic Actuator Valve For Reverse Osmosis System

Reverse osmosis (RO) system uses the principle of reverse osmosis to remove mainly dissolved salts from water while removing some macromolecules and small particles etc. that were not removed in the previous stage. The pneumatic actuator valves can play a lot of roles in this system. It is mainly driven by pressure, forcing the solvent […]

COVNA Automated Valves For Brackish Water Desalination

What is Brackish water desalination? Brackish water desalination is actually the desalination of salt water, so that the salt water is desalinated or treated to meet the drinking water standard. There are many methods of desalination of brackish water and seawater, mainly distillation, electrodialysis and reverse osmosis. At present, reverse osmosis and electrodialysis are mostly […]
