Air Control

Air control in pressurized water systems is critical for increasing efficiency during filling, draining and pressurized operation, as well as to provide protection from vacuum conditions and pressure surges. The presence of uncontrolled quantities of air in water systems can seriously affect performance, causing inefficient filling and draining procedures and flow reduction, while increasing energy costs. It also disrupts the operation of some system components. Air control in pressurized water systems is critical for increasing efficiency during filling, draining and pressurized operation, as well as to provide protection from vacuum conditions and pressure surge.

Optimized Air Flow & Surge Protection

BERMAD Air Valves include combination and automatic (air release) valves with metal body construction for a variety of clean water as well as sewage and wastewater pipeline and networks. Our air valves offer higher flow rates during pipeline filling (air relief) and draining / vacuum condition (air intake), prevention of air accumulation at pressurized operation, better surge protection, and improved sealing at low-pressure conditions. Most models are certified to leading functional standards and drinking water standards

Benefits

Higher air flows
Low pressure (5 psi; 0.1 bar)
Surge protection devices
Reliable air flow data
Fully certified to leading standards

Smart Use Cases

Typical locations for combination air valves are in pumping stations, deep well pumps, along pipelines, on high points as well as additional locations for automatic air valves in water networks. Effective control of air in a water network is based on evaluating the required air volume during various modes of operation and surge scenarios, and according to the required volume, the proper positioning, sizing, model selection, and inlet sizes of the air valves. BERMAD AIR software is an advanced water system design tool that supports designers in selecting the best air valves for optimized air control in water pipelines and networks while reducing project costs.

Enhancing Air Control in Water Systems with a Combination Air Valve

A combination air valve helps ensure optimal water system efficiency. There are several important factors to consider when selecting combination air valves.

Low Pressure Air Valve Sealing for Reduced Leakage

Air valves are known to leak, especially when located at low pressure points in the water system. This can cause water wastage and interrupt the smooth operation of the water system.
