Welcome to Shanghai Mengsheng Sheng International Trade
Name: High vacuum baffle valve
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Description :
This series of valves is divided into three driving modes: manual, pneumatic, and electromagnetic. The structure is designed reasonably, the appearance is beautiful, and it also has the advantages of smooth operation, small size, reliable use, good sealing performance, and long service life. It is one of the preferred valves for vacuum equipment. The valve is powered by manually rotating the handle, compressed air pushing air, and electromagnetic force generated by coil electrification. It is connected to the valve plate through a mechanism and drives the valve plate to open and close. The medium of the valve is air and non corrosive gases.
Scope of application: 1x10^-5 Pa to 1.2x1045 Pa (sealed with fluorocarbon rubber ring)
1x10-6Pa~1.2x105Pa(bellows seal)
Pressure difference on the plugboard when opened:
-DN200-250 (pneumatic): <3x10+Pa
-Others: ≤1.0x105 Pa in any direction
Leakage rate of valve body and valve seat: 1.3×10-7 Pa-L-S-1
First maintenance cycle: 200,000 cycles
Body oven temperature: <150°C
Compressed air (for pneumatic applications only) 0.4-0.7MPa
Time of valve opening or closing
-Pneumatic drive: <1s
-Electromagnetic drive: On ≤0.1s; Off ≤1s (for fluoroplastic seal) or <0.5s (for bellows seal)
Valve Position Indicator
-Manual drive: With open/closed position indication -Pneumatic drive: Equipped with an on/off position indicator switch (magnetic switch)
-Electromagnetic drive: Equipped with an on/off indicator light
Valve weight: Refer to the Weight Manual
installation site :
-Manual drive: Any
-Pneumatic drive: Any (DN ≤ 160); The sealing surface faces the vacuum(DN> 160)
-Electromagnetic drive: Arbitrary (bellows seal); seal- ing surface facing vacuum (fluorocarbon seal ring seal)
source :
-Pneumatic drive: AC 220V 50Hz, 6W or DC 24V,3W (custom specifications available for exceptions to the above parameters)
-Electromagnetic drive: AC 220V 50Hz
