Angle valves,   Inline valves,   Diaphragm valves,   Butterfly valves,   HV gate valves,   UHV gate valves,   Mini angle valves,   Mini inline valves,   Venting valves,   Pressure relief valves,   Gas dosing valves,   Gas regulating valves,   Ball valves

Pfeiffer Vacuum vacuum valves are used in wide-ranging solutions in industrial applications and research areas.
The vacuum valves are divided according to size, type of flange and drive, and according to the pressure range used. There are manually operated vacuum valves with ISO-KF flanges or CF flanges as well as electropneumatically operated vacuum valves that are also offered with ISO-K flanges. The electromagnetically operated vacuum valves are only constructed with ISO-KF flanges due to their operating principle. There are special vacuum valves in all-metal designs for use in the UHV area and vacuum valves, so-called gas metering valves, for controlling pressure as well as for the measured gas supply in vacuum systems. Many of these vacuum valves are available in aluminium and stainless steel.

Poppet Vacuum Valves: Our poppet valves offer superior performance and corrosion resistance. The bodies are die-formed from 304 stainless steel, eliminating sharp inside corners and improving conductance. The welded bellows are made from AM-350 stainless steel, which provides resistance to corrosion.

Ball Valves: Because they are manually operated, ball valves are an affordable solution for dirty or corrosive applications, and are commonly used on MOC VD and CVD equipment to isolate traps or abatement tools. Their simple yet robust design provides high reliability, while their stainless steel body and Teflon seat makes them ideal for corrosive environments.

Linear Gate Valves: Linear gate valves are ultra-slim, making them ideal for applications where space is limited. Because the larger linear gate valves have a unique feature in the actuator, they are well-suited for applications where vibration is an issue, such as semiconductor applications.

All-Metal Vacuum Valves: Our bakeable, all-metal valves are intended for use in high-temperature conditions such as UHV or cryogenic applications. Approved for use in beamline facilities, these vacuum valves have a temperature operating range from -250°C to 400°C.

products:   Large Vacuum Valves

Available in ASA, ISO, rectangular and custom flange configurations from 10" to 60", Mill Lane Large Gate Valves are used for high-vacuum pump isolation and meet the demands of in-line vacuum systems for isolation of process chambers and load locks. Special models may be equipped to operate reliably under hostile conditions of heat, abrasion and particulate accumulation.
Mill Lane's unique Combination Angle Valve with Multi-Coolant Baffle is particularly useful where space is tight. The baffle section slides out for cleaning without disassembly of the pump stack. An optional bellows stem seal extends its utility into the ultra-high vacuum range.
Standard Right-Angle Valves are also available in sizes from 10"- 48".

Vacuum valves play a very important role in determining the efficiency of vacuum equipment and vacuum pumps. Valves used in a vacuum atmosphere work at very small pressure differentials and absolute pressures compared to general industrial pumps. ULVAC provides various vacuum valves based on abundant technological experience in order to meet and surpass customer needs. Be sure to use an applicable ULVAC vacuum valve for work in environments from atmospheric pressure to ultra-high vacuums.
