Air Valve
Aarya Sales is a leading air valve supplier in India, offering a wide range of air release valves, double air valves, and kinetic air valves for efficient pipeline performance. Our valves are sourced from trusted manufacturers and are designed to eliminate trapped air, prevent vacuum formation, and ensure smooth fluid flow.
Single Air Valve (H-4)
Double Air Valve(H-7)
Double Air Valve (H-40)
Double Air Valve (H-7K)
Kinetic Double Air Valve (H-42K)
Tamper Proof Air Valve
Air valves are essential components in pipeline systems, helping to avoid air locks, reduce pressure loss, and protect pipelines from damage caused by water hammer and vacuum conditions.
What is an Air Valve?
An air valve is used in pipelines to release accumulated air during operation and allow air intake during draining or emptying. This ensures efficient flow, protects pipeline integrity, and improves system performance.
Types of Air Valves We Supply
Single Air Valve
Used for releasing small amounts of trapped air during normal pipeline operation.
Double Air Valve
Designed to release large volumes of air and allow air intake, preventing vacuum conditions.
Kinetic Air Valve
Handles rapid air release and intake, ideal for high-flow and large pipeline systems.

Air Valve Supplier in India — Aarya Sales
Air valves (air release valves / air relief valves) automatically release trapped air from water pipelines during filling and operation, and admit air during draining to prevent vacuum collapse. Aarya Sales supplies single-orifice air release valves, double-orifice (kinetic) air valves, combination (triple function) air valves, and tamper-proof air valves for water distribution networks, irrigation systems, and sewage force mains.
Body materials: Cast Iron (IS 210 Gr FG 260), Ductile Iron, SS 316. Float: SS 316/NBR. Sizes: 15 NB to 300 NB. Pressure ratings: 1.0 MPa to 2.5 MPa (PN 10 to PN 25). Standards: IS 14845, AWWA C512, BS EN 1074-4. Applications: water supply mains, pump discharge lines, irrigation pipelines, sewage rising mains, and fire fighting networks.
Frequently Asked Questions
Air valves (air release/air relief valves) serve three critical functions: (1) Air release — continuously discharge small air pockets during pipeline operation; (2) Air/vacuum break — admit large volumes of air during pipe draining to prevent vacuum collapse; (3) Surge protection — admit/exhaust air during transient events to limit pressure surges.
Single-orifice air release valve: releases small air pockets during pressurized operation only. Double-orifice (kinetic/large-orifice) air/vacuum valve: large-scale air admission/release during filling/emptying only. Combination (triple-function) valve: performs both functions in one body — the most common type for water mains. Tamper-proof design: lockable for public/outdoor installations.
We supply air valves from 15 NB (½") to 300 NB (12") for operating pressures from 0.2 MPa to 2.5 MPa (PN 2.5 to PN 25). Orifice sizes are selected based on pipeline diameter, flow rate, and surge analysis. We can size air valves to IS 14845 and AWWA C512 for your pipeline.
At high points in the profile where air naturally accumulates; immediately downstream of pumps (after the check valve); at regular intervals along long level or downward-sloping pipelines (every 500–1000 m for mains above 150 NB); before and after valves that may cause air pockets; at the end of dead-end mains.
Yes. We supply air valves tested and certified to IS 14845 (Air Valves for Water Supply Installations) by BIS-recognized laboratories. Ductile iron and CI body versions are available with fusion-bonded epoxy (FBE) internal coating for potable water compliance.
A tamper-proof air valve has a lockable cover or cage that prevents unauthorized tampering with the float and orifice mechanism. They are specified for outdoor, roadside, and public area installations in municipal water distribution networks to prevent vandalism and deliberate obstruction of the valve function.
