Overview: 

A ball valve is a type of valve that controls the flow of fluid by rotating the valve core (a ball). Its core structure consists of a ball with a circular hole. The ball rotates around an axis perpendicular to the pipeline axis to achieve full opening (with the hole aligned with the pipeline), full closing (with the ball blocking the pipeline), or flow regulation (partial opening). Ball valves have the characteristics of simple structure, reliable sealing, and low flow resistance. They are widely used in industrial fields such as petroleum, chemical engineering, natural gas, water treatment, and civil pipeline systems.

Overview: 

A gate valve is a type of valve that controls the opening and closing of a pipeline by the vertical movement of a gate plate (the closing element). The valve achieves this by either sealing or releasing the contact between the gate plate and the valve seat, thereby enabling the flow of fluid to be turned on or off. Its sealing performance depends on the cooperation between the gate plate and the valve seat, and it is widely used in industries such as water supply and drainage, petrochemicals, power, and metallurgy. 

Nominal diameter: 10mm ~ 1000mm and 1/2" ~ 60" 

Nominal pressure: 1.0MPa ~ 16.0MPa/150Lb ~ 1500Lb/10K ~ 160K

Drive methods: manual, worm gear transmission, bevel gear, electric, pneumatic, hydraulic, etc.

Overview: 

A stop valve is a type of valve that controls the flow of fluid by the up-and-down movement of the valve disc (the closing element) along the centerline of the valve seat. Its working principle is to achieve the interruption, regulation, or throttling of the medium in the pipeline through the sealing surfaces of the valve disc and the valve seat coming into contact or separating. The stop valve has the characteristics of a simple structure, reliable sealing, and good regulating performance. It is widely used in pipeline systems where precise control of flow or frequent opening and closing are required. 

Nominal diameter: 10mm ~ 1000mm and 1/2" ~ 60"

Drive methods: Manual, worm gear transmission, bevel gear, electric, pneumatic, hydraulic, etc.

Overview: 

A check valve is a type of valve whose opening and closing element is a circular disc that moves due to its own weight and the pressure of the medium to prevent the backflow of the medium. It belongs to the category of automatic valves and is also known as a reverse flow valve, a one-way valve, a return valve, or a isolation valve. The movement mode of the valve disc is divided into vertical lift type and rotary opening type. Check valves are widely used in scenarios such as the outlet of water pumps, steam pipelines, and compressor systems where reverse flow prevention is required. 

Nominal diameter: 10mm ~ 1000mm and 1/2" ~ 60"

Overview: 

The butterfly valve is also known as the flap valve. It is a simple structure regulating valve that can be used for the on-off control of low-pressure pipeline media. The butterfly valve refers to a type of valve where the closing element (valve disc or butterfly plate) is a circular disc and rotates around the valve axis to achieve opening and closing. Valves can be used to control air, water, steam, various corrosive media, slurry, oil products, liquid metals, radioactive media and other types of fluid flows. On pipelines, it mainly plays the role of cutting off and throttling. The butterfly valve's closing element is a disc-shaped butterfly plate, which rotates within the valve body around its own axis to achieve the purpose of opening or closing or regulation.
