1.OEM & customization capability
2.Our own foundry(Precision casting/Sand castings) to guarantee fast delivery and quality
3.MTC and inspection report will be provided for each shipment
4.Rich operating experience for project orders
1.Swing check valve is generally suitable for the pipe structure with clean fluid medium,not suitable for the working condition with high viscosity or containing solid particles, otherwise it will lead to the unsensitive opening of the check valve, unable to achieve complete sealing, and the check effect on the fluid will not reach the ideal effect.
2.The valve bearing parts are cast by precision casting process,with beautiful surface quality and no surface defects such as viscous sand and cold isolation. Internal quality is stable, without loose,cracks and other internal defects.
3.Prevent backflow,prevent leakage to the environment in the event of a pipeline rupture,protect the integrity of upstream equipment,always used in petroleum,chemical,pharmaceutical,chemical fertilizer,electric power and other pipelines.
