OEM DN300 Worm Gear GGG50 Wafer Butterfly Valve PN16 Manufacturer, Exporters
Product Description
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.
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.
The body and disc are made from GGG50 ductile iron. GGG50 is a material designation for ductile iron, which has excellent tensile strength, durability, and resistance to impact and fatigue.
