Class150-2500 cast steel swing check valve


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.

Class 150~300 Butterfly Swing Check Valve


Class 150~300 Butterfly Swing Check Valve
CLASS 150~300 BUTTERFLY SWING CHECK VALVE
Standards compliance
Design and Manufacture: ANSI B16.34,API 6D
Face to face: API 6D
Flanged connection: 2"~24"to ANSIB16.5,22",26"~36"to MSS-SP-44 to API605 on Request
Test and inspection: API 6D
Shell test 150Lb 450 PSI
300Lb 1125 PSI
Seat test 150Lb 315 PSI
300Lb 815 PSI(Hydrostatic)80PSI(Air)
Features
1. Small in size, light in weight, compact in structure, easy in maintenance.
2. Two torsion springs are used excreting on each of the pair valve plates. Which close the plates quickly and automatically.
3. The quick-close action prevents the medium from flowing back and eliminates water-hammer effect.
4. This valve is short in length, so that it is rigid and easy to mount.
5. It is easy to install on pipeline which is laid horizontally or vertically.
6. This valve is tightly sealed without leakage under the pressure water test.
7. Safe and reliable in operation, high interference-resistance.
8. The connection dimensions of flanges accord with the standards of GB4216-84 GB4216.84
9. The face to face dimensions are in accordance with GB12221-89.ISO5752-82. The stem of the valve should be perpendicular to the horizontal level when the valve is mounted on horizontal pipeline. For vertical installation the direction of flow should be downward.
