Series SCAV AWWA C512 Sewage Combination Air Valve – 2″

The VSI Series SCAV Combination Air Valve features both a large and small orifice in a single elongated body to effectively vent air and gasses from sewage forcemains. The large piston orifice allows large amounts of air to vent from the system as it is being filled. Once filled, the small orifice allows accumulation and residual air and gasses to be released while the system is in operation. When the system is drained or negative pressure is experienced in the forcemain the large orifice opens to allow free inflow of air to prevent pipe collapse.

The Series SCAV should be installed at system high points, in places where accumulation of air and gasses are expected during filling, would collect during normal operation, or where vacuums would form.
