Flanged High-Speed Combination Air Valve PN16 for Water Supply And Fire Water Pipeline System

The High-Speed Combination Air Valve is designed for water supply, fire water, pump station and pipeline systems. It can quickly discharge large volumes of air during pipeline filling, admit air during pipeline draining or vacuum conditions, and release accumulated air during normal operation. This valve helps protect the pipeline system, improve flow efficiency and reduce pressure fluctuation.

FAQ

What is a high-speed combination air valve used for?

It is used to discharge air, admit air and protect the pipeline system from air blockage, vacuum damage and pressure fluctuation.

Where should this valve be installed?

It is usually installed at pipeline high points, pump outlets, long-distance pipelines and positions where air may accumulate.

Is this valve suitable for fire water pipelines?

Yes, it can be used for fire water pipeline systems, subject to project requirements and approval.

What is the difference between a combination air valve and an automatic air release valve?

An automatic air release valve mainly releases small amounts of air during operation. A combination air valve can discharge large volumes of air, admit air during vacuum conditions and release accumulated air during normal operation.

What pressure ratings are available?

PN16, PN25, PN40 and PN63 can be supplied according to project requirements.

Can the flange standard be customized?

Yes. EN, DIN, BS, ANSI or project-required flange standards can be supplied according to customer requirements.
