Check valve is also known as the reverse valve or one-way valve, is dependent on the flow of the medium itself and automatically open, close the valve disc, generally used in the pipeline system, its main role is to prevent the medium in the pipeline backflow, prevent pump and drive motor reversal, and prevent the release of the medium in the container. Check valve is automatically opened and closed by the force generated by the flow of medium itself in the pipeline, which belongs to an automatic valve. It is suitable for water, steam, oil, nitric acid, acetic acid, strong oxidizing medium etc.
Here are our check valve API594 for american customer.
And here is the technical drawing.
Size range: 2"~64"(DN50~DN1600)
Pressure grade: ASME CLASS 150~2500 (PN16~PN420)
Main material: carbon steel, stainless steel, alloy steel and duplex steel
Connection mode: RF, BW, RTJ
The characteristics
1. Streamline valve channel design, low fluid resistance.
2. The opening pressure is small, the valve disc can be opened under the small pressure difference.
3. Disc with spring assisted check mechanism, check response is more sensitive.
4. Disc guide mechanism, open and close flexible, no jam phenomenon.
5. The valve cavity with nominal pressure ≥PN160 (Class900) adopts pressure self-sealing structure, the higher the pressure, the better the sealing performance.
Structural description：
1. No external leakage, good sealing performance, little linear vibration, low pressure drops, etc.
Disc is swing type, straight flow, can be installed both horizontal and vertical pipes. Casting steel swing check valve hinge and pin is built-in structure to reduce external leakage defects. Bolted body bonnet, no other actuator, makes the product light weight and reliable in sealing.
1. Full diameter design, small pressure loss, large disc opening angle.
2. The opening pressure is small; the disc can be opened under small pressure difference.
3. American standard check valve adopts built-in pin shaft structure, which reduces leakage point and makes use more reliable.
4. Slow-closing mechanism can be set as required.
5. Replaceable seat structure can be designed according to requirements.
6. The valve cavity with nominal pressure ≥PN160 (Class900) adopts pressure self-sealing structure, the higher the pressure, the better the sealing performance.
