Double clamp swing check valve

H76 double-disc pinch swing check valve has the characteristics of short structure length, small volume, light weight, quick disc closing, small water hammer pressure, easy installation, small fluid resistance, sensitive action, good sealing performance, short disc stroke, small closing impact force, simple and compact overall structure, long service life and high reliability.

The double-disc swing clamping check valve is composed of body, disc, stem, spring and other parts. It adopts clamping connection and has compact structure. Due to the short closing stroke of the disc and the spring loading, the closing speed is fast, which can significantly reduce the phenomenon of water hammer. The product has the characteristics of small volume, light weight, sensitive action, reliable sealing, easy installation, etc. It can be installed horizontally or vertically, and can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and other media.

Double flap swing clamp check valve is suitable for nominal pressure PN10 ~ PN420, Class150 ~ Class2500; Nominal diameter DN15 ~ DN1200, NPS1/2 ~ 48; The operating temperature of -196 ° C ~ 540 ° C is used to prevent the backflow of the medium. By selecting different materials, the clamp check valve can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media in petrochemical, metallurgy, electric power, light industry, food and other industries.

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.

Structural features:
