High Flow Air Release Valve - Durable Irrigation Solution from China Suppliers & Factory, Optimized for Efficient Air Management
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
What is the main purpose of the RAIN LING Air Release Valves?
They are designed to automatically manage air within irrigation pipelines. By releasing trapped air and providing vacuum protection, they prevent uneven pressure and potential system damage, ensuring stable and efficient water flow.
What sizes are available in this series?
The RL-VP Series is available in 3/4”, 1”, 1.5”, and 2” connection sizes, featuring BSP or NPT male thread types to accommodate different piping systems.
Where should these valves be installed?
It is recommended to install the valves vertically at system high points, filter outlets, or near valve assemblies where air is most likely to accumulate or where vacuum conditions may occur.
What material are these valves made of and are they durable?
They are constructed from premium reinforced PP plastic. This material provides superior UV resistance, excellent mechanical strength, and ensures a long service life even in harsh outdoor environments.
What is the working pressure range for the RL-VP Series?
The series operates smoothly under a working pressure range of 0.3 to 15 bar, making them highly versatile for both low-pressure and high-pressure irrigation systems.
