Product Details
Product Details
- Stainless steel stem
- Series 401 and larger model APCO sewage air/ vacuum valves are specifically designed for operation on sewage and waste media
- Air/Vacuum valves are needed to vent large volumes of air when the sewage line is filled and allow air to reenter when draining
- Once closed, and pressurized, the air/Vacuum valve will not open to release air
- It will open under negative pressure allowing air to re-enter and prevent vacuum from forming in the line
