Premium Rubber Lined Concentric Butterfly Valve by CTGV
A Rubber-Lined Concentric Butterfly Valve is a type of butterfly valve designed for corrosive or abrasive fluid control, featuring a rubber-lined interior for enhanced durability and chemical resistance.
Body structure: 1pc body
Construction: Concentric / center line butterfly valve
Bore:Full bore
Connection: Flange ASME B16.5 or ASME B16.47 flange
Seat: Replacable seat 1. Excellent Corrosion & Chemical Resistance
The rubber lining (EPDM, NBR, Viton, etc.) protects the valve body from corrosive fluids (acids, alkalis, seawater, etc.).
Ideal for chemical processing, water treatment, and marine applications.
Bubble-Tight Sealing
The soft rubber seat ensures zero leakage when closed, making it suitable for high-purity or hazardous media.
Better sealing than metal-seated valves in low-pressure applications. 3. Smooth Flow & Low Pressure Drop
Concentric design ensures minimal turbulence, improving flow efficiency.
Suitable for HVAC, water distribution, and low-pressure systems.
