ball valve
The main structure of a ball valve is to use a ball with a circular through-hole as the opening and closing element, and the ball rotates with the valve stem to achieve the opening and closing action of the valve. The structure of a ball valve is similar to that of a plug valve, and some people also refer to it as a spherical plug valve. It consists of a sphere and two valve seats (sealing rings) to form a sealing pair. The commonly used materials for valve seats are polytetrafluoroethylene and hard alloys. The ball valves produced by Shanghai Meiyan Yi Pump Valve have a wide range of applications, with working pressures ranging from high vacuum to high pressure (up to 40 megapascals), working temperatures ranging from -196 to+450 ℃, and a maximum diameter of 1000 millimeters. According to the sealing structure principle of ball valves, ball valves are divided into floating ball valves, fixed ball valves, etc. Floating ball valves mainly rely on fluid pressure to press the ball onto the valve seat at the outlet end, forming a floating seal, thus limiting the pressure and diameter used. The ball of a fixed ball valve is supported by two upper and lower bearings installed on the valve body, and the position of the ball is fixed. The sealing effect is achieved by the spring and fluid pressure pressing the valve seat against the ball, so the opening and closing torque is much smaller than that of a floating ball valve, which is suitable for high-pressure and large-diameter applications. Three way ball valves and four-way ball valves are used for fluid reversing pipelines, with T-shaped and L-shaped options.

Pneumatic ball valves
Pneumatic ball valve refers to a pneumatic valve composed of various types of pneumatic angular stroke valve actuators and ball valve brackets, as well as integrated ball valves, two-stage ball valves, three-stage ball valves, limit switches, pneumatic triplets, solenoid valves, etc. Pneumatic ball valve is a type of valve that operates on the principle that the opening and closing components are driven by the valve stem and rotate around the axis of the ball valve. The plug body of the ball valve is a spherical body with a circular through-hole or channel passing through its axis. It can be opened, closed, or adjusted by rotating 90 degrees. The pneumatic ball valves manufactured by Shanghai Meiyanyi Pump Valve are mainly characterized by compact structure, good sealing performance, simple principle, and easy maintenance. They are suitable for general working media such as water, oil, and air, and are also widely used in various harsh working environments.View details>>

Electric ball valves
Electric ball valve refers to an electric control valve composed of switch type, regulating type, intelligent angular stroke electric valve actuator, or multi turn electric installation and integrated ball valve, two-piece ball valve, and three-stage ball valve. The voltage of the electric actuator is 220V single-phase and 380V three-phase, and voltage signal or current model can be selected to control the opening and closing or regulating of the valve. The electric ball valves produced by Shanghai Meiyanyi Pump Valve are widely used in industries such as petroleum, chemical, food, and power due to their advantages of low fluid resistance, easy operation, and simple structure. The valve part of an electric ball valve is a type of valve that operates on the principle that the opening and closing components are driven by the valve stem and rotate around the axis of the ball valve. The plug body of the ball valve is a spherical body with a circular channel passing through its axis, which can be opened, closed, or adjusted by rotating 90 degrees.View details>>

Floating ball valves
Floating ball valve refers to the valve core structure of a ball valve that can freely float within a certain range according to the elasticity of the valve seat seal. It mainly relies on the circular valve seats on the left and right sides as the fulcrum. Floating ball valves can be divided into manual, turbine, electric, pneumatic, and hydraulic transmission types according to different driving modes to meet different usage scenarios and needs. The floating ball valves produced by Shanghai Meiyan Yi Pump Valve generally have a diameter within DN15-DN300 and a pressure between PN16-PN100. The working principle is mainly based on its unique central axis rotation motion design, which makes its sealing performance particularly outstanding in fluid control systems. It is widely used in various industrial fields such as water, oil, steam, natural gas, liquefied gas and other transportation pipelines and storage equipment.View details>>

Fixed ball valves
Fixed ball valves mainly refer to the valve core, that is, the structural form of the valve ball. In addition to the floating fixation of the valve seats on the left and right sides, the upper and lower valve stems also have fixed support. Structurally speaking, the sealing form of fixed ball valves requires higher requirements than floating ball valves. In addition to the sealing surfaces of the ball valve core and the left and right valve seats, the accuracy of the upper and lower valve stems also needs to be taken into account. The fixed ball valves produced by Shanghai Meiyan Yi Pump Valve are more suitable for large-diameter and high-pressure working conditions, especially for large-diameter American standard fixed ball valves, which have particularly stable quality. The main working principle is that the valve's plug body is a spherical body with a circular through-hole or channel passing through its axis, which can be opened, closed or adjusted by rotating 90 degrees.View details>>

Forged steel ball valves
Forged steel ball valve refers to a ball valve whose body material is manufactured by forging process, divided into forged steel and forged stainless steel. The forged ball valve body is generally a two-stage or three-stage structure, especially suitable for ball valves under high pressure conditions. It is a valve whose operating principle is that the valve core is driven by the valve stem and rotates around the axis of the ball valve. The plug body of the ball valve is a spherical body with a circular through-hole or channel passing through its axis. It can be opened, closed or adjusted by rotating 90 degrees. The main feature of forged steel ball valves produced by Shanghai Meiyanyi Pump Valve is exquisite forging technology, which is widely used in industrial pipelines for liquids and gases such as oil pipelines, natural gas pipelines, liquefied gas pipelines, etc. with high temperature and high pressure.
