Check valve installed in the pipeline system, its main role is to prevent media flow back, check valve is a kind of media pressure open and close automatically. In the past, the most commonly used is H44 flange connection swing check valve and H41 flange connection lift check valve, this traditional check body product is big, fluid resistance, water hammer pressure is high when the valve is closed, installation, maintenance is difficult, short service life.
Aiming at the existing problem of traditional structure check, our API standards and DIN standards as the basis, combined with our company for many years in the valve test research, development, design, processing and manufacturing of rich experience, developed the H76 type double disc swing check valve to the clamp and H71 wafer lift check valve series products, After years of use by petrochemical, metallurgy, electric power, light industry, food and other industries of enterprises and equipment manufacturers, the effect is good, well received by users.
