Manual hard-sealing butterfly valve, hard-sealing butterfly valve, manual butterfly valve, butterfly valve

The manual hard-sealed butterfly valve adopts a three-dimensional eccentric principle design, which ensures that the spatial movement trajectory of the sealing surfaces is idealized. There is no friction or interference between the sealing surfaces, and with the appropriate selection of sealing materials, the sealing performance, corrosion resistance, high-temperature resistance and wear resistance of the butterfly valve can be reliably guaranteed. 

Characteristics of Manual Hard-Sealed Butterfly Valve 

1. The operating torque is small, the operation is convenient and labor-saving, and it is flexible and efficient.

2. The three-dimensional eccentric structure enables the butterfly plate to close tighter and tighter, and its sealing performance is reliable, achieving zero leakage.

3. It is resistant to high pressure, corrosion, wear, and has a long service life.

The manual hard-sealed butterfly valve is suitable for use in food, pharmaceutical, petrochemical, industrial environments, as well as in high-rise buildings and pipelines, for regulating flow and serving as a flow-cutting device.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
