01
Gate Valve Series
A gate valve is a valve whose opening and closing components are gate plates that move up and down along the centerline of the valve seat. It has the characteristics of low fluid resistance and low torque required for opening and closing, and can work in fully open or fully closed states. It is not suitable for adjustment or throttling. Widely used in water supply and drainage, petroleum, chemical and other fields, it can be divided into wedge gate valves and parallel gate valves according to its structural form.
02
Globe Valve Series
A globe valve is a valve whose opening and closing components are valve discs that move up and down along the axis of the valve seat. It has good sealing performance and can accurately adjust the flow rate. It is commonly used to cut off or adjust the flow direction of media. The fluid resistance is high, and a large torque is required for opening and closing. Widely used in steam, compressed air, oil and other pipeline systems, it is divided into straight through and right angle types according to the channel direction, and is one of the commonly used control valves in industrial pipelines.
03
Check Valve Series
A check valve is a valve that automatically opens and closes based on the flow of the medium to prevent backflow. The valve disc opens when the fluid flows forward and closes when it flows backward, effectively preventing the backflow of the medium. It has the characteristics of simple structure and reliable action, and does not require manual operation. Widely used in pipeline systems such as water supply and drainage, heating, and chemical engineering, it can be divided into lifting, swing, butterfly, etc. according to its structure, and is an important device to ensure the safe operation of pipeline systems.
04
Ball Valve Series
A ball valve is a valve with a spherical opening and closing element that rotates 90 degrees around the centerline of the valve body to control its opening and closing. It has the characteristics of simple structure, reliable sealing, and minimal flow resistance, and can quickly open and close and accurately adjust the flow rate. Suitable for water, gas, oil and particulate media, easy to operate and maintain. Widely used in fields such as petroleum, chemical, and natural gas, it is divided into floating ball, fixed ball, and track type according to its structure. It is a control valve in industrial pipelines that combines sealing and durability.
05
Butterfly Valve Series
Butterfly valve is a valve with a disc-shaped butterfly plate as the opening and closing element, which rotates around the axis of the valve stem to control the opening and closing of the valve. It has the characteristics of compact structure, small volume, and low flow resistance, and can quickly open, close, and adjust flow rate. Small operating torque, low installation space requirements, suitable for media such as water, gas, and slurry. Widely used in water supply and drainage, gas, chemical and other fields, it is divided into soft seal and hard seal according to the sealing form, and is a commonly used energy-saving valve in industrial pipelines.
06
Metallurgical Valve Series
Metallurgical valves are valves designed specifically for high-temperature, high-pressure, dust, and corrosive media working conditions in the metallurgical industry. Capable of endurance
High temperature resistance, impact resistance, and other characteristics can be used to control gas, flue gas, cooling water, etc. in processes such as blast furnaces, converters, and steel rolling
Medium. Divided by function into shut-off valve, regulating valve, directional valve, etc., the structural design takes into account both sealing and resistance to harsh environments
Strength is a key equipment in metallurgical production lines that ensures process safety and efficiency.
07
Water Control Valve Series
Hydraulic control valve is a valve used for automatic regulation and control of water flow in hydraulic systems. Move through water pressure or other media
Power realizes opening and closing and flow regulation, with functions such as voltage stabilization, pressure relief, and water level control. Can be used for water supply and drainage, farmland irrigation
Maintain system Pressure stability to prevent water hammer impact in irrigation and water conservancy projects. Divided by function into pressure reducing valve, check valve
Pressure relief valves and other structures designed to adapt to hydraulic conditions are important devices for ensuring the safe and efficient operation of hydraulic systems.
08
Other Valve Series
More than 800 specification series, widely used in power, chemical, petroleum, metallurgy, refining, medicine, oil transportation, and transportation
In industries such as gas pipelines and urban construction.
