High Flow Air Release Valve - Reliable China Factory Suppliers for Drip and Sprinkler Systems
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.

Frequently Asked Questions
Q1:
What is the primary function of the RAIN LING Air Release Valves?
The primary function is to ensure efficient and stable water flow by automatically managing air within irrigation pipelines. They release trapped air and provide vacuum protection to maintain consistent hydraulic performance and prevent system damage.
Q2:
What material is used for the RL-VP Series valves?
The RL-VP Series is constructed from high-quality reinforced PP (Polypropylene) plastic, which offers superior UV resistance, excellent mechanical strength, and a long service life under harsh operating conditions.
Q3:
What sizes and thread types are available?
The valves are available in sizes of 3/4”, 1”, 1.5”, and 2”. They feature BSP/NPT male thread connections (25 mm, 32 mm, 50 mm, and 63 mm respectively) for broad compatibility.
Q4:
What is the recommended installation position for these valves?
It is highly recommended to install the valves in a vertical position at system high points, filter outlets, or near valve assemblies where air is most likely to collect.
Q5:
What is the working pressure range for the RL-VP Series?
The recommended working pressure range for these valves is between 0.3 and 15 bar, supporting stable performance under both high and low pressures.
Q6:
What applications are these air release valves suitable for?
Thanks to their precision-engineered structure and robust PP plastic construction, they are ideal for residential, commercial, and agricultural irrigation systems.
