Overview: Air valves for sewage

Model SCF 2"
The air valve will ensure the proper operation of the sewer line allowing the release of air in working conditions, the evacuation and the entrance of the air during filling and draining of the pipeline.

Model SCA 2"
The non slam air valve will protect the system from the water hammer effect produced by the sudden shut off of pumping stations allowing the entrance of a huge amount of air, avoiding negative pressure, to evacuate it slowly in order to cushion further overpressure.

Model SCS 2"
The air valve, entirely built in stainless steel, will ensure the proper operation of the sewer line allowing the release of air in working conditions, the evacuation and the entrance of the air during filling and draining of the pipeline.

Model SCS-AS 2"
The non slam air valve, entirely built in stainless steel, will protect the system from the water hammer effect produced by the sudden shut off of pumping stations allowing the entrance of a huge amount of air, avoiding negative pressure, to evacuate it slowly in order to cushion further overpressure.

Model SCF
The air valve for water will ensure the proper operation of the sewer line allowing the release of air in working conditions, the evacuation and the entrance of the air during filling and draining of the pipeline.

Model SCF-AS
The non slam air valve SCF-AS guarantees the proper operation of pressurized sewage systems allowing the release of air pockets in working conditions, the entrance of large quantities of air in case of pipe bursting or draining operations and a controlled air outflow speed to minimize the risk of water hammer events.

Model SCF-RFP
The SCF-RFP is a wastewater combination air valve to ensure the proper operation of sewage systems with air release during working conditions, air entrance and discharge during pipe draining and filling phases. In addition to that SCF-RFP features a new technology triggering the non slam function, whenever required, in case of excessive air speed allow for pipeline protection against water hammer events.
