High-quality double-acting air release valve for wastewater and raw water that protects against air accumulation and vacuum in the pipeline.

BERMAD C50-P is a high-quality double-acting air valve for wastewater and raw water. It evacuates large volumes of air whilst filling pipelines, enables efficient venting of pressurised pipe systems, and allows a large air intake when draining the system. With its advanced aerodynamic design, this double-acting air valve provides excellent protection against air accumulation and prevents vacuum formation, with improved sealing under low-pressure conditions. Available with a service port that allows easy function checks or fitting of, for example, a pressure gauge. Supplied as standard without a service port.
