Clamp lift check valve

The H71 clamp lift check valve has the characteristics of short structure length, small size, light weight, quick disc closing, small water hammer pressure, easy installation, small fluid resistance, sensitive action, good sealing performance, short disc stroke, small impact force, simple and compact overall structure, long service life and high reliability.

Scope of application:

The pinch lift 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:

1. The structural length is short, and the structural length is only 1/4 to 1/8 of the traditional flange check valve;

2. Small size and light weight, its weight is only 1/4 to 1/20 of the traditional flanged check valve;

3. The valve disc closes quickly and the water hammer pressure is small;

4. Horizontal pipe or vertical pipe can be used, easy to install;

5. The flow path of the clamp-lift check valve is smooth and the fluid resistance is small;

6. Sensitive action, good sealing performance;

7. Short stroke of valve disc, small impact of closing valve;

8. Overall structure, simple and compact, beautiful shape;

9. Long service life and high reliability.
