Detailed Product Description:

Class150-2500 cast steel swing check valve Characteristics of API Check Valve 1. Design and manufacture of ptoduct according to American state standard ANSI B16.34, American petroleum institute standard API6D. 2. Small opening pressure, the disc can be opened fully with a very small pressure differential. 3. Rocker and hinge pin use inside-set design, reduces outer leakage point. 4. The body and bonnet of class 1500~Class 900 check valve is connected with stud. And the body and bonnet of class 1500~class 2500 check valve pressure seat structure to make product bulk small, weight light, seal credible.
