API ASME Swash plate type check valve
HH512BF swash plate check valve（Description）
Swash plate check valves are widely used in pipeline systems to prevent liquid backflow hazards and protect machinery and equipment. They not only have the functional characteristics of general check valves, but also have the superior characteristics of reducing water hammer hazards, reducing noise, reducing pressure drop and rapid response. With axial symmetry structure and streamlined flow channel, pressure loss is very small, special manufacturing technology to ensure zero leakage of high requirements, but also has the opening and closing of no impact, maintenance-free and simple installation advantages, suitable for all kinds of gas, liquid media, and has been installed in any way.
Design features
1.Venturi type channel to reduce pressure drop
2.Spring protection, no collision
3.Low noise, very small water hammer hazard
4.Soft seal, secondary seal
5.Hard seal, fire proof design
6.Full range of lugs and legs available
7.The valve has no possibility of media leakage
Product features
Swash plate check valve is composed of valve body, guide body, axial motion disc and spring components. The product can effectively prevent medium backflow. Ensure pipeline safety.
The valve body, disc and tail are designed into streamlined channels, which have good fluid performance and reduce flow resistance and pressure to a large extent.
The use of high performance spring material HT/INCONELX-750, with excellent corrosion resistance, oxidation resistance and excellent mechanical properties, to ensure the long-term work of the spring, running state.
4、Silent operation, so as to eliminate the noise and water hammer in the valve pipeline to ensure the safety of equipment and pipeline.
5、Open and close the reaction is quick, high reliability of the prepressure spring so that the disc to fluid pressure changes quickly response.
6、Compact structure, easy to install, vertical, horizontal installation can be.
7、The valve adopts alloy steel surfacing sealing surface, wear resistance, corrosion resistance, long life.
8、The valve pressure range is relatively wide.
Technical specifications
| Design standard | API 6D 、ASME B16.34 |
| Structure length | ASME B16.10 |
| Connecting port | ASME B16.5、ASME B16.25、GB 9113、GB 12224 |
| Test standard | API 598、ISO 5208、JB/T9092、GB/T13927 |
| Operating mode | The disc opens and closes automatically by medium force |
| Field of use | Water, steam, oil, natural gas, etc |
| Note 1 | The sealing surface of the valve seat and disc is surfacing with hard alloy to improve the scour resistance of the valve and extend the service life of the valve |
| Note 2 | Streamlined flow channel, medium does not flow around, valve flow resistance is small, save energy. |
| Note 3 | Suitable for preventing medium backflow in pipes or devices |
| Note 4 | The FLOATING DISC structure can automatically compensate the error
caused by wear during installation and use, ensure the sealing surface to fit closely, and improve the sealing performance. |
| Note 5 | The opening and closing stroke is short, and can be automatically reset without impact. At a small flow rate, the valve can be fully opened and the closing time is short |
