PRODUCT DESCRIPTION

RAIN LING Air Release Valves Series ensures efficient and stable water flow by automatically managing air within irrigation pipelines.

Trapped air or vacuum pockets can cause uneven pressure, reduce water delivery, and damage system components. These valves provide reliable air release and vacuum protection, maintaining consistent hydraulic performance in all operating conditions.

Constructed from reinforced PP plastic, the RL-VP Series offers superior UV resistance, excellent mechanical strength, and a long service life.

Its precision-engineered structure supports smooth operation under both high and low pressures, making it ideal for residential, commercial, and agricultural irrigation systems.

Available Sizes: 3/4”, 1”, 1.5”, and 2”
Connection Type: BSP/NPT male thread
Recommended Installation: Vertical position at system high points, filter outlets, or near valve assemblies.
