Product Description

FREE-VALVE PVC/UPVC/PVDF Plastic Flanged End Swing Type Check Valve  refers to the valve that automatically opens and closes the disc by relying on the force generated by the flow of the medium itself to prevent the medium from backflowing.Plastic swing check valves are swing type and have a plastic disc that swings about a hinge pin or shaft,the valves are normally designed for horizontal flow condition, the flow should be in upwards direction and under the disc.This series of check valves is widely used in pipeline transmission lines with corrosive media.

Features

1. The eccentric mounted hinge pin in combination with the disc seat guarantees a positive shut off of the returning medium.
2. Bolt bonnet provides easy access to the disc and hinge pin without removing the valve from the pipeline in case of maintenance.
3. Disc nut secures the disc to the hinge and allows the disc to rotate about pin axis and assist in tight shut off.
4. Working temperature:

FRPP -14ºC~ +90ºC,UPVC -10ºC~ +60ºC,PVDF -40ºC~ +150ºC,CPVC -20ºC~ +95ºC

5. Fasteners can be made of engineering plastics in contact with the medium, so that the valve is more corrosion resistant.
6.  Low liquid flow resistance, the inner wall of plastic molding products is smooth, and the friction coefficient is small.
7.  Excellent chemical properties: this product, tasteless, acid and alkali resistance, corrosion resistance, wide range of use.
