VACUUM ■ VACUUM SERVICE BALL VALVES "V" SERIES General Habonim's "V" Series Vacuum Service ball valves offer reliable and economical solutions for applications that require Vacuum Service valve operation. Standard Habonim ball valves can easily be converted for effective use in Vacuum Service applications down to 20 microns, and with specific preparation, can also perform in higher Vacuum Service applications, down to 10-6 mm of mercury (torr). Vacuum Vacuum is defined as a space in which the pressure is far below normal atmospheric pressure, so that the remaining gases do not affect processes being carried on in the space. High Vacuum Applications Applications include; Plasma Processing and Research, Thin Film Coating, Atmospheric and Space Simulation, Gas and Materials Analysis, Materials Research and Processing, Vacuum Metallurgy and Joining Techniques, Environmental Testing and Lab Applications. | ||||||||||||||||||||||||||||||||||||||||||||||||||
Although there are numerous methods for measuring Vacuum Service, some of the most common measurements are shown in the table below. | ||||||||||||||||||||||||||||||||||||||||||||||||||

Test results carried out by independent testing laboratories may be obtained for an additional fee. In cases of independent testing, it is vital that customer's supply the following information: degree of vacuum to be upheld, unit of measurement, maximum permissible leakage rate. For your convenience, a Pressure Conversion Table appears on the back. Design | ||||||||||||||||||||||||||||||||||||||||||||||||||
Habonim Vacuum Service valves are available with screwed, socket weld, butt weld, ANSI Class 150 and ANSI Class 300, DIN PN16 and DIN PN40 flanged ends. Flanged valves range from 1/2" to 8", and three piece valves from 1/4" to 6". Body materials include 316 stainless steel and carbon steel. Standard ball and stem material is 316stainless steel. TFM,NRL PTFE or glass filled PTFE seat and seal materials are used for Vacuum Service applications, and stem seals also include Viton O-ring.
