A valve that is designed to allow the fluid to flow in a given direction but closes to prevent backflow. Types include swing check, tilting disc check and wafer check. Check valves (also called non-return valves) are usually self-acting.
The above attached product' s specification is as follow:
General description
Tilting disc check valve is a new check valve produced by our company referring to the foreign advanced products. Its main advantages are to overcome the bump, water hammer of swing check valve and lift check valve under the working condition to achieve smooth operation.
Design code
- Design conform to ASME B16.34
- Structural dimension：ASME B16.10
- Flange dimension：ASME B16.5 GB HG SH
- Inspection and test：API 598
- Pressure class：Class 150、300、600 PN 2.0 、5.0、10.0 MPa
Structural features
- While closing, the seat ring can get in touch with the sealing face gradually. then the double-eccentric center disc can work well without bump and noise.
- Flexible metal seat is of good seal performace.
- The disc with butterfly form has a long cycle life with quick open and close.
The tilting type makes flow passage streamlined to reduce the flow resistance and save the energy.
