Zhuzhou Southern Valve Co.,Ltd. products

Installed in the outlet pipe of the pump in the pumping station of water intaking, water sending, pressurization and sewage, the valve has three functions as electric driving valve, check valve and water hamper eraser. The valve features in minimum failure, tightly closing and reliable for water hamper erasing, which not only ensures the safety and reliability of water supply, but also satisfies the automation demands of water supply engineering equipments.

Installed not only in water-intake, water delivery, pressurizing, submersible, and sewage pumping stations in municipal, construction, steel, metallurgy, petroleum, chemical, food, pharmaceutical, power, water conservancy and irrigation industry , but also in delivery system of oil & chemical fluid. The valve has 3 functions as electric driving valve, check valve and water hammer eliminator, which can effectively improve security and reliability of the system, and meet the requirements for automatic control and energy saving.

The liquid control butterfly valve, also known as liquid control slowly-closing butterfly valve, is perfectly controllable and widely used in hydropower station as inlet main control valve for the turbine, or used in pumping stations, as outlet control valve.

The butterfly valve is widely used in municipal water company`s pipe network, cooling water systems, hydroelectric systems, sewage treatment plants, diversion works, chemical and smelting industry,  water supply & drainage and power generation systems for raw water, water, corrosive gases , liquid and multiphase fluid, with the function of cutting off and non-return.

It is usually installed in water, oil, steam, gas (natural gas) delivery systems, in such fields as oil, petrochemical, gas (natural gas), power station, nuclear power, metallurgy, food, medicine, especially for applications with higher sealing requirements.

It is usually installed in water, oil, steam, gas (natural gas) delivery systems, in such fields as oil, petrochemical, gas (natural gas), power station, nuclear power, metallurgy, food, medicine, especially for applications with requirements for fully-opening or fully-closing.

Installed outside all kinds of sewage pools’ body to drain sludge and other filth from pool bottom.

It is installed at the bottom of various funnel-shaped sewage pool in order to exclude the sediment and dirt.

This valve is installed in the exit of the pump and the top of the pipe, so it can breathe and array lots of air, it still can array the dram air that in the water in order to protect the pipes, guarantee the pipes export water normally.

Avoid the vent being stopped by float ball in hi-speed air steam, thus invalidating the exhaust valve. Protection sleeve would be set up at the entrance of the traditional valves to avoid blocking, thus making the structure complicated. The unique features are as follows: simple structure; high reliability; never blocking no matter how speedy the air velocity is.
