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
