Key features/benefits
Air Release Valves serve two main purposes:
- Release trapped air pockets present in pipelines.
- Re-introduce air into the pipeline when flow rates drop/pumping is halted.
Older generations of Air Release Valves feature bulky designs, with singular functionality – this meant that end users would have to accommodate this bulk and install multiple valves for release and reintroduction of air to secure their pipelines.
Magwen Air Release Valves features 4 Function, Non-Slam operation in a single, lightweight and compact package. The 4 functions executed are:
1. Release of large volumes of high velocity air out from pipelines during initial stages of pumping
2. Release of air pockets featuring smaller volumes and low velocity that may develop during regular operation.
3. Reintroduction of air into pipelines when pumping stops and line media is drained (prevents damage due to vacuum pockets).
4 Function Non-Slam operation – reduces back flow velocity of the media column and weakens Water Hammer effect.
Additionally, Magwen’s Air Release Valves offer users the following advantages:
- Compact single chamber design.
- Tamper-proof, anti-theft construction for enhanced line security.
- Jamming free and maintenance free operation using lightweight, self centering polypropylene floats.
- Complete protection from corrosion through effective material selection and full in-house fusion bonded epoxy coating.
