The technical indicators of high vacuum baffle valve mainly include the following aspects:1Body Material:

Generally, stainless steel material is used, which has good corrosion resistance and high temperature resistance. 2.Vacuum:

The void degree of the true crack key of the high vacuum orange car baffle valve should reach below 10-6pa, which can meet the requirements of the high vacuum system. 3.Leakage rate:

The leakage rate of the high vacuum baffle valve should be less than 10-9pa·m3 s, which can ensure the tightness of the system. 4.Pressure Resistance:

The opening and closing time of the high vacuum baffle valve should be short, generally between 1-2 seconds. 6.Drive mode:

The driving mode of high vacuum baffle valve can be divided into manual, electric, pneumatic and other methods, among which the pneumatic and clever driving mode is the most widely used. 7.Dimensions and connections:

The size and connection method of the high vacuum baffle valve should be selected according to the specific use scenario, usually using flange connection or clamp connection.

Hello dear, glad to answer for you. The High Truth Dry Lead Neutral Valve is a valve with a strong seal and very low leakage rate, which is widely used in high vacuum technology. Its main technical indicators include the following:

1.Leakage rate: High vacuum valves work in the vacuum range of tens of Pa to 10-8 Pa, so the leakage rate of the valve is extremely high, usually requiring the leakage rate to be below 10-10.

2.Starting pressure: The starting pressure of the high vacuum baffle valve is very low, which is required to be in the range of tens of pascals (PA).

The low starting pressure ensures reliable opening and closing of the valve under high vacuum. 3.Seal form:

High vacuum baffle valves are usually sealed in a metal-to-metal seal, which ensures that the valve has good high temperature resistance and explosion-proof capabilities. 4.Inlet size and shouting light deflation rate:

The inlet size of the high vacuum baffle valve is usually a standard KF, ISO or CF flange, and the inlet and bleed port diameter and bleed rate must match the size of the vacuum chamber and the pumping speed of the pump. 5.Material:

The body and valve plate of the high vacuum baffle valve need to be made of high-purity stainless steel or other suitable materials to avoid contamination of the vacuum environment by material evaporation. The above are the main technical indicators of high vacuum baffle valves, which need to be reasonably selected and configured according to specific application scenarios and requirements.

High vacuum baffle valves are used to turn on or off the air flow in the vacuum line. The applicable medium is pure air and non-corrosive gas. According to the shaft seal structure, the high vacuum baffle valve can be divided into two types: GD-J rubber shaft seal and GD-J (B) bellows shaft seal.

According to the conduction form, GD-J can be divided into angle pass type, and GD-S can be divided into three-way type with pre-draw.

Body, bonnet, stem: aluminum, carbon steel or stainless steel.

Seals: nitrile rubber, fluoroelastomer, bellows (shaft seal).

Dear, glad to serve you High vacuum baffle valve is a commonly used high vacuum equipment, which is commonly used in semiconductor manufacturing, vacuum evaporation, solar cell and photovoltaic plate production and other fields. Its main technical indicators are as follows:1

Maximum operating pressure: usually 10 -5 10 -9 bar level; 2.Leakage rate:

Usually does not exceed the maximum leakage rate standard corresponding to the nominal diameter code of the valve; 3.Operating temperature range: varies according to different working environment and structural materials, generally -20 to +150; 4.

Valve caliber Fan Qiao's brother: generally from DN16 to DN630; 5.Interface Standards:

GB, ISO, DIN and other international standards or industry standards; 6.Air tightness test: test according to GB T, ISO, DIN and other standards; 7.

Life requirements: It is usually required that the number of opening and closing times is more than 100,000 times, and the valve can be maintained well. It should be noted that there will be differences in the technical specifications of different types of Gaozhen Xiao wide attack neutral plate valves, please carefully understand the product parameters before purchasing.

Thank you for your patience, I hope mine is helpful to you, if you are satisfied, please give me a thumbs up and wish you a happy life.
