High Conductance Vacuum Valves
from Edwards Vacuum
Ball valves are popular in applications where fast action and full bore pumping are needed. The Edwards IBV series valves combine these practical everyday features plus ease of use and economy in a high specification design. Manufactured in 316L stainless steel with PTFE seats they deliver robust... [See More]

These straight-through valves with electromagnetic (solenoid) drive are used for operating cycles with short intervals and, therefore, are often used as vacuum control valves. The straightforward design provides a valve with low leakage rate. The valves in VV "C" versions (e.g., VV-B 6C) are made of... [See More]
- Features: High conductance
- Port OD: 0.9843
- Type: Inline; Straight Through
- ISO Port Flange Size: NW 25

The Edwards GV range of stainless steel bellows sealed gate valves are designed for applications requiring overall leak tightness and a minimum of hydrocarbon in the residual atmosphere. These superior quality valves offer high vacuum integrity coupled with maximum conductance. [See More]
- Features: Bellows; High conductance
- Port OD: ? to 1.5
- Type: Gate
- Vacuum / Pressure Range: Low or roughing vacuum level (> 1 torr); Low / Medium (HV < 1 torr, >10-3 torr); (HV, < 10-3, >10-8 torr); (UHV, < 10-8 torr)

High vacuum, helium leak-tested right angle valves VE have stainless steel bellows which seals the drive mechanism without any gap on the vacuum. Due to the screw-thread mechanism, these valves offer a certain control of conductance and are mountable in any position because of their air tightness in... [See More]

VK series ball valves are sturdy isolation devices for the rough and fine vacuum range. A precisely machined ball with a hole through the middle is rotated by means of shaft and lever. When the valve is open, the hole provides unimpeded passage of media over the entire nominal cross section. Ball... [See More]

The QSB quarter swing valves are compact, quick acting, high conductance isolation valves. The QSB valves have a polished, stainless steel, ISO flanged body with fluoroelastomer 'O' ring sealed valve plate and shaft. The valve plate 'O' ring groove is vented to help maintain a stable high vacuum. [See More]
- Features: High conductance; Position indicator
- Port OD: ? to 4.02
- Type: Butterfly
- Vacuum / Pressure Range: (UHV, < 10-8 torr); Elevated or positive pressures (>> 760 torr)

The VS series valves are butterfly-type valves. A circular valve plate with a sealing ring on the circumference rotates around an axis at right angle to the valve axis. As a result, the valves leave virtually the entire cross section free, offering very good conductance. The valve bodies are made of... [See More]
