Product details
Introduction to D371X-16 Worm Gear Butterfly Valve
D371X-16 worm gear butterfly valveSuitable for regulating flow and intercepting media on water supply and drainage, gas pipelines with temperatures ≤ 80-120 ℃, such as food, medicine, chemical, petroleum, electricity, textile, papermaking, etc.
Characteristics of D371X-16 Worm Gear Butterfly Valve
1. This valve adopts a double eccentric structure, which has a sealing function that becomes tighter as it is closed, and the sealing performance is reliable.
2. The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber, which has a long service life.
3. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from.
4. The butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance.
5. The overall baking paint can effectively prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced.
6. This valve has a bidirectional sealing function and is not controlled by the flow direction of the medium or the spatial position during installation. It can be installed in any direction.
7. This valve has a unique structure, flexible operation, labor-saving, and convenience.
