Custom Check valve series
A check valve is also called a non-return valve, a one-flow valve, a one-way valve or a non-return valve. Its function is to ensure that the medium in the pipeline flows in a directional manner without backflow.
It is used in pipelines of various working conditions in the petroleum, chemical, pharmaceutical, fertilizer, power industry, etc., and is suitable for media such as water, oil, steam, acidic media, etc.
Custom Control valve series
Control valves are used to regulate the flow, pressure, and level of a medium. Based on signals from the regulating element, they automatically control the valve opening, thereby regulating the flow, pressure, and level of the medium. Control valves are classified into electric, pneumatic, and hydraulic control valves.
Custom Butterfly valve series
Butterfly valve, also known as flap valve, is a regulating valve with a simple structure. It can also be used for on-off control of low-pressure pipeline media. It is a valve that rotates around the valve shaft to open and close. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

Ball valves are primarily used in pipelines to cut off, distribute, and redirect media flow. Ball valves designed with a V-shaped opening also offer excellent flow regulation. They are suitable for frequent operation, offering quick and easy opening and closing. They also feature low fluid resistance, a simple structure, a relatively small size, light weight, and ease of maintenance.
Butterfly valve, also known as flap valve, is a regulating valve with a simple structure. It can also be used for on-off control of low-pressure pipeline media. It is a valve that rotates around the valve shaft to open and close. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
Globe valves are suitable for shutoff, regulation, and throttling. Because their stems have a relatively short opening or closing stroke and offer highly reliable shutoff, and because the change in seat opening is proportional to the disc's stroke, they are ideal for flow regulation. They can be used to control the flow of various fluids, including air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media.
Check valves, also known as non-return valves, one-way valves, one-way valves, or non-return valves, ensure the directional flow of media in pipelines without backflow. The foot valve in a pump suction pipe is also a check valve. Check valves are automatic valves used in pipelines in various industries, including the petroleum, chemical, pharmaceutical, fertilizer, and power industries. They are suitable for media such as water, oil, steam, and acidic media.
The gate valve is a gate that opens and closes. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed. The gate parameters vary, usually 5°, and 2°52' when the medium temperature is not high. To improve its processability and compensate for the deviation of the sealing surface angle during the processing, this gate is called an elastic gate.
