Electric stainless steel valve

Introduction to Electric Stainless Steel Valve Products

The corrosion of the medium in the electric valve leads to the aging of the electric control valve, causing internal leakage. After a period of time, due to cavitation and erosion of the medium, wear of the valve core and seat, aging of internal components, and excessive power regulation authority, the electric valve is not tightly closed, and the leakage of the electric valve increases. Over time, the leakage of electric valves will become increasingly severe.
　　
Electric stainless steel valves include stainless steel ball valves, stainless steel globe valves, stainless steel check valves, stainless steel plunger valves, etc. Electric stainless steel valves can be divided into switch control type and intelligent regulation type (4-20mA analog signal control) according to different working modes and conditions. The sealing forms include soft seal and hard seal. The electric actuator works by rotating the valve stem to drive the disc plate to open and close within the range of 0-90 °.
　　

Classification of stainless steel ball valves

Stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. The material of stainless steel ball valves is divided into 304, 316, 321 stainless steel ball valves.
　　
Stainless steel ball valves can be tightly closed with only a 90 degree rotation and a small rotational torque. The completely equal valve body cavity provides a low resistance, straight through flow channel for the medium. The main characteristics of a ball valve are its compact structure, easy operation and maintenance. Stainless steel ball valves 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. The valve body of a ball valve can be integral or modular. This type of valve should generally be installed horizontally in pipelines.

Stainless Steel Ball Valve Purchase Notice

　　
It should also be reminded that do not rush to choose products. First, understand what are the popular electric ball valve products and their performance. The way to understand these is to contact multiple electric ball valve manufacturers, ask them to provide product catalogs, styles, etc., compare prices from three sources, and then choose cost-effective products.
　　

Working principle of electric flange butterfly valve:

　　
The electric flange butterfly valve uses an electric actuator to input a standard signal of 0-10mA, and the motor unit drives the gear turbine worm to rotate the disc plate with angular torque. When the valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by this valve is very small, thus it has good flow control characteristics. Electric flange butterfly valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate. Valves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the drawback of being limited by temperature. If an electric flange butterfly valve is required for flow control, the main thing is to correctly select the size and type of valve.
