Combination Air Valve for Sewage & Wastewater with Surge Protection, Reduced port
Ductile Iron (code 475)
BERMAD VEC-313-C-R is a quality combination air valve for a variety of sewage and wastewater networks and operating conditions. It evacuates air during pipeline filling, allows efficient release of air and gas pockets from pressurized pipes, and enables the intake of large volumes of air in the event of network draining.
With its advanced aerodynamic design, double orifice and Surge Protection (Anti-slam / slow closing) device, this valve provides excellent protection against air accumulation, vacuum formation and pressure surges.

- Straight flow body with nominal (equal) inlet and outlet size.
- Elongated body design: Prevents solids from making contact with valve’s operating parts.
- Surge Protection: the kinetic orifice is partially closed during the second stage of the air relief, preventing damage to the air valve and the system and increasing the operational time without maintenance.
- Drainage Valve: 1"; DN25 female threaded BSP.
- Simple, robust structure with fully corrosion-resistant parts: Lower maintenance and increased life span.
Typical Applications
- Pumping stations and deep well pumps: Air relief, surge protection and vacuum prevention.
- Non clean water pipelines: Protection against air and gas accumulation and vacuum formation at elevations, slope change points and at road/river crossings.
- Wastewater treatment plants: Air relief, protection against air and gas accumulation and vacuum formation.
