AIR RELEASE AND VACUUM VALVES

Maintaining and/or replacing air release valves to help protect a wastewater pipeline’s system and maintain its efficiency is essential to preventing premature failure. Air release valves play a critical role in pressured pipelines, quickly venting large volumes of air during filling or startup, as well as normal operating conditions, and allowing air back into the pipeline during emptying, thus eliminating negative pressure. Malfunctioning air valves can cause air lock and pipeline collapse. In wastewater force main applications, it can promote the conversion of H2S gases to H2SO4, sulfuric acid, accelerating damage to the crown of a sewer force main resulting in premature failure and decreasing remaining lifetime use.

CPM Pipelines performs maintenance, repair and replacement to air release and vacuum valves in the water and wastewater industry, and our technicians are confined space entry certified.  We offer products from industry leading manufacturers H-TEC and VSI Waterworks providing long-term solutions for distribution and collection systems.

H-TEC distributes innovative and high-quality valves and fittings for potable water and wastewater systems, manufactured in Germany. Their state-of-the-art products are benchmarks in terms of functionality, corrosion resistance and long-term cost savings for the pipeline operator. The quality corrosion protection uses the fluidized bed epoxy power coating system.

VSI Waterworks has manufactured butterfly, plug, gate, ball and check valves since 1995. All valves are manufactured using ductile iron as a standard for bodies and discs/gates, providing a tensile strength double that of cast iron. Shafts are stainless steel 304, and the EPDM for seats and seals is peroxide or sulfur cured.
