Product Specifications and Overview

A Spherical Disc Butterfly Valve uses a disc with a curved or spherical profile to control fluid flow through a pipeline. The disc rotates around a shaft, typically through 90 degrees, to open or close the flow passage. Its design is intended to support smooth operation and effective sealing when the disc, seat and valve body are correctly matched.

The valve can be used in industrial systems where dependable shut-off, compact installation and straightforward operation are important. Depending on the design, it may be operated manually through a lever or gearbox, or fitted with a pneumatic or electric actuator for automated operation.

Spherical disc butterfly valves can be used in water supply, wastewater treatment, HVAC, process industries and other compatible fluid-handling applications. The correct selection depends on the valve design, disc and seat materials, operating pressure, temperature, fluid characteristics and required leakage performance.

Frequently Ask Questions

It is a butterfly valve that uses a curved or spherical-profile disc to control fluid flow through a pipeline.
The profile influences the disc's interaction with the flow and seat. Its exact benefits depend on the valve's geometry and design.
The key difference is the disc geometry. The effect on sealing, flow characteristics and operating torque depends on the complete valve design.
The disc rotates around a shaft. When the disc aligns with the flow, the valve opens; when it turns across the passage, it restricts or shuts off flow.
Some butterfly valves can regulate flow, but their suitability for continuous throttling depends on the disc design, flow conditions and manufacturer's recommendations.
Some operating mechanisms may require lubrication, but the valve seat and disc should only be lubricated if the manufacturer specifies it. Follow the maintenance instructions for the particular model.
