A Wafer Actuated JJ Ductile Iron Bronze Disc Valve is a type of butterfly valve designed for controlling flow in pipelines. It features a ductile iron body with a bronze disc for durability, corrosion resistance, and smooth operation.

They are widely used in HVAC systems, water treatment plants, marine environments, and general industrial applications where reliable flow control and corrosion resistance are required.

The wafer design allows the valve to fit between two flanges in a pipeline, held in place by flange bolts. This compact construction saves space and simplifies installation.

A bronze disc provides enhanced corrosion resistance, making it ideal for applications involving water, seawater, or mildly corrosive fluids, while maintaining strength and longevity.

These valves feature a ductile iron body, bronze disc, and EPDM or NBR seat, offering a strong combination of structural integrity, sealing performance, and chemical resistance.

They can be fitted with pneumatic, electric, or manual actuators, depending on the control requirements of the system.

Yes, when paired with the appropriate actuator and control accessories, they can be used for both on/off isolation and modulating flow control.

JJ Wafer Actuated Butterfly Valves usually conform to PN16 or ANSI 150 pressure ratings, depending on the model and configuration.

While primarily designed for positive pressure systems, they can be used for low vacuum conditions if properly specified and tested.

Routine inspection and cleaning of the disc and seat area are recommended. Actuators should be checked periodically for air leaks (pneumatic) or electrical performance (electric).
