This series of valves is suitable for disconnecting pipelines in ultra-high vacuum systems, and it has two driving modes: manual and pneumatic. It has the advantages of smooth operation, reliable use, good sealing performance, and long service life, and is one of the preferred valves for ultra-high vacuum equipment. A manual valve is powered by manually rotating a handle through threaded transmission to open and close the valve plate. The direction of opening and closing is based on the markings on the handle; Pneumatic valve is powered by compressed air to open or close the valve plate. When the air source is lost, the valve plate will automatically close by the spring force. The medium of the valve is air and a few corrosive gases.
Characteristic:
1.Standardized and modular design, easy to replace and maintain;
2.Easy to clean design;
3.The shaft seal is a corrugated tube seal, and other seals are made of fluororubber, with no lubricant design;
4.The valve body is welded internally with stainless steel, resulting in a low leakage rate;
Basic Specifications:
Scope of application: 1x10-6 Pa to 1.2x105 Pa
Pressure difference on the valve plate when open: <1.2x10 Pa in any direction
Leakage rate of valve body and valve seat: <1.3×10-7 Pa.Ls-'
First maintenance cycle: 200,000 cycles
Valve body baking temperature: ≤200ºC when open; ≤150C when closed
Installation location: Any
Power supply: AC 220V 50Hz, 6W or DC 24V,3W (customizable for special specifications)
