COVNA Valves For Tannery Wastewater Treatment

Tannery wastewater refers to wastewater produced during the preparation and tanning stages of tanning production, i.e. during wet operations. Wastewater contains heavy metals, dander, dyes, resins, etc. If wastewater is discharged directly without treatment, it can be detrimental to the ecological environment and have an impact on human health.
Therefore, wastewater treatment is very necessary for the tanning industry and the whole enviroment, which can effectively reduce pollution to the environment and improve the utilization rate of water resources.

A valve is an industrial device used in the wastewater treatment system of a tannery to transfer water flow to speed up production. Each process has different requirements for valves, pumps, piping and other industrial fittings. Therefore, choosing the right valve can make the whole system run more smoothly.

In this article, we will introduce you to valves that can be used for tannery wastewater treatment. Hope to help you understand and choose the right valve.


Since tannery wastewater contains impurities, a Y-type strainer is necessary. It filters out impurities in the water and keeps the pipes running smoothly.

Check Valves

The check valve is a valve that prevents the backflow of the medium and can ensure the normal operation of the pipeline. Generally used next to pumps, water meters, motors and other electrical equipment. To protect the proper functioning of electrical equipment.

Gate Valves

The gate valve is a valve that can only be fully opened and fully closed. It can only circulate or block the flow of the medium, but cannot adjust the flow. Its advantages include large flow and low resistance. Remote control or on-site control can be achieved through electric actuators, pneumatic actuators or handwheels.


Ball Valves

The ball valve is a quarter-turn valve. Its structure is simple, easy to operate and easy to install. The ball rotates 90 degrees with the stem, which opens or closes the valve. Ball valves can be used for circulation, blocking, adjustment, confluence or diversion to meet your various needs. The ball valve has a variety of connection methods, including thread type, flange type, clamp type, and welding type.

Similarly, the ball valve can be driven by an electric actuator or a pneumatic actuator to achieve the purpose of remote control of the valve.

Butterfly Valves

Butterfly valve is a commonly used valve. Its advantages are large size, low fluid resistance, compact design and easy installation. The valve plate rotates 90 degrees with the valve stem to open or close the valve. According to the difference of seals, butterfly valves can be divided into soft-sealed butterfly valves and hard-sealed butterfly valves to match the needs of various pipelines.

We can provide electric butterfly valve, pneumatic butterfly valve and manual butterfly valve for you to choose to meet your driving needs.

The above is the introduction of valves that can be used for tanning wastewater treatment. If you have any needs for valves, you are welcome to consult us and get the best valve plan and budget plan.
