Vacuum Butterfly Valves

A butterfly valve has high flow conductivity for turn on or cut off the vacuum airflow called vacuum butterfly valve. Vacuum butterfly valve and vacuum ball valve are two types of common vacuum valves. The applicable media is air and non-corrosive gas. In order to get the control automatically, solenoid valve and position indicator are optional device.

  • Butterfly Valve with Butt-weld Ends
  • Butterfly Valve with KF Flange
  • Butterfly Valve with ISO Flange
  • Butterfly Valve Handles

Features:

  • 1. Valve Sizes from 1/2″ to 6″
  • 2. Forged body and disc for better quality.
  • 3. Standard Materials are 304 and 316L stainless steel.
  • 4. Vacuum Range: >=10-8 Torr
  • 5. Various manual or automatic operators available.
  • 6. Polyacetal bushings for the valve disc reduce friction and increase cycle life.
  • 7. Optional wing nut kit is available for effortless valve assembly and disassembly.
  • 8. Butterfly valves are supplied with a machining finish. Other finishes are also available.
  • 9. The system can afford up to 400 Fahrenheit (200 Celsius ). However, sustained heating above 302 Fahrenheit (150 Celsius ) may result in deterioration of the gasket.
  • 10. Valve sets are 100% tested before shipping.
  • 11. Seat materials in Viton, Silicon, and EPDM.
  • 12. Seat Temperature Range:
      • Fluorocarbon FKM (Viton): Celsius -5 to 204 ( Fahrenheit 23 to 399)
      • Silicon: Celsius -50 to 180 ( Fahrenheit -58 to 356)
      • Ethylene Propylene Diene Monomer (EPDM): -50??135 ( Fahrenheit -58 to 275)
