Concentric Disc Butterfly Valve Supplier in India — Aarya Sales
Concentric (rubber-seated) butterfly valves have a disc and stem centred on the valve's axis, sealing against a resilient (rubber) liner that also serves as the body gasket. Aarya Sales supplies concentric disc butterfly valves in sizes 50 NB to 2700 NB, PN 6 to PN 16, for water, air, and low-pressure process service.
Disc materials: Cast Iron, Ductile Iron, SS 304/316. Liner materials: EPDM (water, air), NBR (oil, fuel), Viton (chemical/high temperature). Wafer and lug body styles. Economical choice for HVAC, water distribution, and general utility isolation service.
Frequently Asked Questions
A concentric butterfly valve has its disc and stem centred on the valve bore's axis, sealing against a resilient rubber liner that lines the entire body. It is the most economical and widely used butterfly valve design, suited to low-pressure isolation and throttling in water, air, and general utility service.
Typically rated PN 6 to PN 16, with temperature limited by the liner material — EPDM handles up to about 110°C in water/steam service, NBR up to 90°C for oils, and Viton up to around 200°C for chemical or higher-temperature applications.
EPDM for water, air, and mild chemicals; NBR for oils, fuels, and hydrocarbons; Viton for aggressive chemicals or elevated temperatures. Liner selection should always be checked against the specific fluid's chemical compatibility.
We supply concentric disc butterfly valves from 50 NB to 2700 NB in wafer (between-flanges) and lug (dead-end capable) body styles, in Cast Iron, Ductile Iron, and Stainless Steel disc/body combinations.
