Sant Valves AV Brass Air Vent Valve, PN 16
Sizes: 15 mm, 20 mm, 25 mm
Brass air vent valve that releases trapped air from high points in water pipework. Rated PN 16 and up to 100°C, in 15 mm to 25 mm.
Air release valves let trapped air out of water mains, risers and pipework, float valves shut off tank filling as the water level rises, balancing valves set the flow in water circuits, and plumbing valves such as stop valves, bib taps, ferrules and drain valves serve the building's water service. Fire Protection System supplies these from Sant Valves, Kartar Valves, Zoloto and Aaag in Bhopal and across Madhya Pradesh.

For air release on mains, match the valve to the job. A single orifice valve bleeds small pockets of air from a main under pressure, while a double orifice kinetic air valve adds a large opening that moves air while a main fills or drains. Kartar Valves makes both to IS 14845: screwed single orifice valves (K543, K544, Type S1 and S2, 15 mm to 50 mm) and flanged double orifice kinetic valves (K541, K542, Type DK, 40 mm to 200 mm) with rubber or SS floats. It also offers ductile iron PN 1.6 valves such as the tamper proof compact K542.C, the triple action K549 and the compact K550, and the K-945 and K-946 from its fire fighting list in PN 16, plain or with an isolation ball valve. Fit air valves at the high points of hydrant mains and water pipework, where trapped air collects.
For dry risers and small lines, Aaag offers air release valves in gunmetal (G152) or stainless steel (SS152), made to bleed air from a dry riser, with a 25 mm male BSP or NPT inlet and a test pressure of 21 bar. Kartar Valves offers a gunmetal spring loaded air release valve (K904-S, K616, PN1.0, 15 mm to 25 mm) and a forged brass air vent with a built in strainer (K907), Sant Valves the AV brass air vent valve, rated PN 16 and up to 100°C in 15 mm to 25 mm, and Zoloto a chrome plated forged brass air release valve (1095) in 15 mm, 20 mm and 25 mm.
For tank filling, the Sant Valves FBV5 forged brass horizontal plunger float valve shuts off the supply as the water level rises, with screwed BSP ends from 15 mm to 50 mm. For setting flow in water circuits, Sant Valves and Zoloto offer double regulating balancing valves in two size bands: from 15 mm to 50 mm (the forged brass Sant Valves SBBV from 20 mm, up to 150°C, and the screwed bronze Zoloto 1087 to BS 7350, PN 16, with test cocks and a lock shield) and flanged from 65 mm to 300 mm (the ductile iron Sant Valves CIBV, up to 120°C, and the cast iron Zoloto 1087A to BS 7350, flanged to BS 4504 PN 16). Kartar Valves also offers a sight glass (K905) that shows whether water is flowing in the pipe.
For building water service, Sant Valves offers a brass stop valve and bib tap made as per IS-781, an export pattern bib tap, a JCS WR type bronze ferrule, an IS 2692 bronze ferrule cock from 8 mm to 50 mm, a gun metal drain valve with union nut and tail pipe, and a bronze taper plug main valve. Check the thread type before ordering: most of these use BSP or IS-554 parallel threads, while the ferrules use taper threads. Kartar Valves lists its flanged single orifice air release valve with a photo only and supplies its K547, K548, K553 and K554 air valves on request, so FPS confirms size, body and rating with the maker before quoting.
