Vacuum Relief Valves
Crispin Vacuum Relief Valves
• Allows air to enter
system when
vacuum occurs
• Prevents air
exhaustion during
pump start-up
RISPIN Vacuum Relief Valves allow large volumes of air to enter
a system when a vacuum occurs, but prevent air from being
exhausted upon pump start-up. If desired, this trapped air column
could be exhausted by the addition of a small orifice air release valve.
This controlled release allows air to act as a cushion to help prevent
potential surge. Vacuum Relief Valves are installed at high points in the
line, or as directed by the engineer, to relieve a vacuum due to column
separation or draining the line.
