Wastewater combination air valve Mod. SWV 3S

SWV 3S air valve guarantees the proper operation of sewage lines allowing the entrance and the discharge of large volumes of air, during pipe draining and filling operations, and the release of air pockets during working conditions.

• Large lower body designed with strongly sloped funnel shaped walls to avoid deposit of grease or other material, and containing four ribs obtained by casting to guide the stainless steel float.
• Upper body containing a casing that protects the air release device against spurts during rapid filling.
• Mobile block including a large AISI 316 stainless steel float, placed on the lower body, and connected through a stainless steel rod to the air release system.
• Flat obturator in solid polypropylene to avoid deformations and to prevent it from remaining stuck to the gaskets, while other materials have the tendency to do it.
• Drainage valve for chamber control and draining.
• Nozzle and gasket holder wear resistant thanks to gasket compression control.
• Maintenance can be easily performed from the top without removing the air valve from the pipe.
• Evacuation bend in polypropylene standard for DN 50/65 and on request for other DN (trough SUB kit).
