China Worm Gear Operated CF8 Disc Double Stem Wafer Butterfly Valve Manufacturer, Exporter
Product Description
CF8 Disc
CF8 is cast grade 304 stainless steel, has excellent corrosion resistance and is widely used in various applications, including corrosive fluids.
Double Stem
In a double stem butterfly valve, the disc is supported by two stems rather than a single central stem. This design can provide better disc stability and reduce the potential for disc wobble.
Worm Gear Operated
The valve uses a worm gear as its operating mechanism, known for their ability to provide high torque at low speeds and for their capability to lock the valve position due to the gear's self-locking nature.
