Air & Vacuum Release Valves
Air/Pressure Relief Valves
- Designed to relieve air pressure at a specific pressure setting (customer to advise when ordering -
typical setting 15-25 PSI)
- Air Relief Flow Rates:
- A2180 up to 500 SCFM
- A2182 up to 1400 SCFM
- A3180 up to 1300 SCFM
- All 2180 and 2182 series valves use white food grade, high temperature (400°F) elastomer diaphragms.
- Tamper proof safety is improved by replacing old wire/lead seals with new cup seals which are more secure.
- In the US the customer can choose the preset pressure tolerance:
a) the conventional tolerance is set pressure +3/-0 PSI
b) the "A" absolute tolerance is set pressure +1/-0 PSI. The tighter tolerance air reliefs are designated with the prefix "A".
(A2180, A3180, A2182)
- For the Canadian market only the "A" or absolute (+1/-0 PSI) tolerance air reliefs are available.
Note: Adjustable models A2180ADJ and A3108ADJ are only available with absolute (+1/-0 PSI) tolerance settings
and are adjustable + or - 3 PSI from specified setting.

Vacuum Relief Valves
Vacuum relief valves are safety valves which relieve vacuum (instead of pressure) when exceeding a
specific setting. Customers must advise vacuum settings required when ordering - typical estting
10-18 inches of mercury. Typical construction includes an aluminum top, anti-galling alloy inlets,
bronze valve, stainless steel spring, male inlets, and female outlets.
