COVNA Valves For Ultrafiltration Membrane System

The ultrafiltration membrane system is a highly automated device that removes microorganisms, viral pathogens, and organic matter. It is used to filter and purify water to ensure the needs of human life and production. Valves are also essential equipment in ultrafiltration membrane systems.

Below, we will introduce you to the valves that can be used in ultrafiltration membrane systems. Hope to help you understand and choose the right valve.

Butterfly Valves

The advantages of butterfly valves include ease of switching, ease of operation, compact design, saving installation space, low fluid resistance, and a wide range of sizes. Most importantly, the parts of the butterfly valve can be replaced according to the needs of the industry, such as the material of the seal and the material of the valve plate.

We can provide pneumatic butterfly valve, electric butterfly valve and manual butterfly valve for you to choose to meet your driving needs. The advantages of pneumatic actuators include cost-effectiveness and quick response. The advantages of electric actuators include intelligence and high torque. The advantages of manual butterfly valves include low cost. You can choose according to the design of the project.

heating-pipeline

COVNA Valves For Heating Pipeline

The heating pipeline refers to the transportation of steam or hot water to meet the needs of production and life. Generally used in commercial buildings, residential buildings, etc. In order to be able to better and more accurately regulate the flow of steam and hot water to achieve a comfortable temperature in the room, we recommend the use of automatic valves.
Below, we will introduce you to the valves that can be used in heating pipes. Hope to help you understand and choose the right valve.

Regulating Valves

The regulating valve can be divided into pneumatic regulating valve or electric regulating valve. The pneumatic control valve receives and feedback signals through the positioner, while the electric control valve receives or feedback signals through the electric actuator, so as to achieve precise adjustment of the flow.

Gate Valves

The gate valve is a linear operation valve. The gate moves up and down in a straight line to open or close the valve. Gate valves can only be fully opened or fully closed, so gate valves are suitable for circulating or blocking flow.
According to different designs, gate valves can be divided into rising stem gate valves and non-rising stem gate valves. According to the difference of the actuator, the gate valve can be divided into electric gate valve and pneumatic gate valve to help you control the flow remotely.

Globe Valves

The globe valve is a linear operation valve. The opening and closing angle of the valve plate can be adjusted according to the requirements of adjusting the flow. Globe valves can be used for circulation, cut-off and flow regulation.
According to the different actuation methods, globe valves can be divided into electric globe valves, pneumatic globe valves and manual globe valves.

Ball Valves

The ball valve is a quarter-turn valve. It can be used for circulation, cut-off, diversion, confluence and flow regulation. Wide range of functions and popular. According to the different actuator methods, ball valves can be divided into electric ball valves, pneumatic ball valves and manual ball valves.

Diesel Oil transfer

Butterfly Valves

Due to the large size of the heating pipe, the butterfly valve can be well matched to the demand. The triple eccentric hard seal butterfly valve can withstand high temperatures up to 425 degrees Celsius, so it can be well used for regulating the flow of steam and hot water. According to the different actuation methods, butterfly valves can be divided into electric butterfly valves, pneumatic butterfly valves and manual butterfly valves.

The above is the introduction of valves that can be used in heating pipelines. If you have any needs for valves, you are welcome to contact us for the best valve solution. sales@covnavalve.com

fertilizer-manufacturing

COVNA Valves For Fertilizer Manufacturing

Fertilizer is a nutrient material for the growth of crops made by chemical methods. It can help crops grow and meet the growing demand for food. However, the production of fertilizers and other pesticides generates a certain amount of wastewater. Wastewater treatment is necessary for sustainable development and to meet environmental regulations.

With 20 years of experience in the valve industry, we have provided leading valve solutions for over 1,000 projects to meet the operational needs of various industries. We are committed to helping you increase project productivity, improve project and personnel safety, reduce operating costs, and achieve sustainable growth.

Below, we will recommend suitable valves for you according to the characteristics of the fertilizer production process. Hope to help you understand and choose the right valve.

Fluorine-Lined Ball Valve

Due to the production of chemical fertilizers, corrosive media will be produced. In order to protect the safety of pipes, valves and the overall project, we recommend the use of fluorine-lined ball valves. Lining fluorine is a high-performance material that can withstand strong acid and alkali. The valve body of the fluorine-lined ball valve adopts a metal outer valve body and a fluorine-lined inner valve body. At the same time, a fluorine-lined sphere is used, which can withstand corrosive media. The fluorine-lined valve body is lined with fluorine balls, which double guarantees the safety of the valve.

Electric actuator, pneumatic actuator or handle can be used to drive the fluorine-lined ball valve to open or close.

Fluorine-Lined Butterfly Valve

The fluorine-lined butterfly valve and the fluorine-lined ball valve belong to the same quarter-turn valve. It can circulate or cut off the medium. The fluorine-lined butterfly valve has thickened fluorine-lined seals and fluorine-lined butterfly plates, which can well improve the overall corrosion resistance of the valve, thereby protecting the safety of valves, pipelines and projects.

Electric actuators, pneumatic actuators or handles can be used to drive the fluorine-lined butterfly valve to open or close.

The above is the introduction of valves that can be used in fertilizer processing plants. If you have any needs for valves, please contact us to get the best valve solution and budget cost plan. sales@covnavalve.com

Cosmetics-production

COVNA Actuator Valves For Cosmetic Processing

I am very happy to introduce to you a project we recently completed – cosmetic processing. This project needs to purchase a batch of pneumatic insulation valves for the flow control of grease. This time the delivery time is very urgent, and the customer hopes to ship within a month. By studying the customer’s project requirements and coordinating the production time with the warehouse, our final delivery time is about 10 days. Effectively reduce shipping time and avoid project delays.

Jacketed wafer ball valve is a kind of heat preservation or cold preservation by injecting hot water, steam or cold water. The valve body has a high-performance insulating structure to keep the medium flowing. Suitable for use in grease, asphalt, resin, chocolate, etc. The compact valve body design saves installation volume and low media hold-up.

It can be used with pneumatic actuators or electric actuators for remote control purposes. The advantages of pneumatic actuators are fast response, working life up to 100W times, lightweight, low cost, safety and explosion-proof. Pneumatic actuators can receive or feedback signals through positioners, are compatible with various control systems, and realize remote control and industrial automation. Electric actuators can directly feedback or receive signals to help you achieve the purpose of remote control. Its advantage is intelligent integration, no additional air source is required, and electric actuators with different functions can be provided according to the requirements of the working conditions.
