Rubber-Seated Butterfly Valves to AWWA C504, designed for drink water, sea water, cooling water etc. NSF/ANSI 61 approval is available.
Design is rated for B valves (max. flow velocity 16ft/sec-4.9m/sec), and absolutely compliance with the requirements in min. shaft diameter, min. body shell thickness and actuator test cycles, workshop testing and Proof-of-design tests etc.

BFV-02-QJ Rubber lined Butterfly Valve, internally with ebonite lining of thickness 3mm or 5mm.
The typical applications of this type of butterfly valves are chemical plants, sea water treatment, desalination projects, nuclear power plants, water treatment, TSE, sewage etc.

This kind of butterfly valve has the unique advantages:
– Keeping the main valve closed and bypass valve open. That can maintain minimum flow across the valve to avoid water stagnancy and maintain water quality.
– Equalize the pressure across the valve to enable manual opening in case of power unavailability.
