Plate Valves
Plate Valves provide operators with a comprehensive range of both metallic and non-metallic plate valve assemblies and internal components, manufactured to the highest quality, for air and process gas compressors operating in a range of different applications. Achieving the optimum performance and reliability are key to most operators and plate valves can deliver across the broad spectrum of applications and operating conditions required.
The plate valve in the PVA range is one of the most well known high vacuum valves, which has been fitted in many facilities and systems for over thirty years now. They are still known as the high Vacuum Valves with one of the highest conductance rates. This is mainly used in diffusion pumps, but can also be used together with cryogenic and turbo pumps.
