Air Valves

STF Air Release Valands are a durable and efficient component used in irrigation systems.
When the valand is full, it automatically closes until the cycle is complete and then allows air to flow back into the system.

The air release valand helps preandnt clogging of the emitters due to back suction and maintains the long-term operating performance of the system.
They also help preandnt water hammer at the start of an irrigation cycle.

These valands release air as the system fills with water and automatically close when fully filled.
By preandnting back suction, it preandnts emitters from clogging, reduces water hammer and maintains the long-lasting
performance of the system.
