Valves

The Covenant Distributors range of valves include: pipeline isolation, gate, ball, soft start, backing/roughing, diaphragm, air admittance and butterfly valves. Selecting a valve for your vacuum system is made easy with Covenant Distributors.

When you design a vacuum system, your choice of valve will be determined by the need for certain operating parameters. When selecting a valve for your vacuum system, consider all of the parameters detailed below:

  • Actuation - manual, solenoid or pneumatic
     
  • Leak tightness - related to the vacuum operating level
     
  • Dirty system tolerance - high tolerance needed for dense particulate
     
  • Size - dependant on the size of your vacuum system
     
  • Pressure range - maximum and minimum pressure are both important
     
  • Port configuration - right angle or in-line
     
  • Maximum baking temperature - for high temperature processes
     
  • Life - mean time before failure
     
  • Relative conductance - high conductance for high flow or throughput and rapid pump-down
     
  • Position indication - local or remote indication
     
  • Closure speed - solenoid or pneumatic for fail-safe rapid valve closure
     
  • Corrosion resistance - stainless steel for corrosive process gases
