Product Description

Iron(Steel) Check Valve Series
The function of Check Valve is to allow the medium to flow in one direction only and prevent the flow in the opposite direction. Usually, the valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the fluid pressure and the dead weight of the valve disc act on the valve seat, thus cutting off the flow.
Check valve can be divided into Swing Check Valve (rotating according to the center of gravity) and Lift Check Valve (moving along the axis).
According to the structure, it can be divided into Lift check valve, Swing check valve and Butterfly check valve
1. Lift check valve is divided into vertical type and horizontal type
2. Swing check valve is divided into three types: single type, double type and multi type.
3. Butterfly check valve is straight through type.
The above check valves can be divided into threaded connection, flange connection, welding connection and clamp connection.

About Cast Iron Material
1.Malleable Cast Iron(MOS Iron/ Magang)                                                                                                                                     
2.Ductile Cast Iron                                                                                                                                        
3.Gray Cast Iron                                                                                                
Feature: Compared with Gray cast iron, Ductile iron in intensity has an absolute advantage. The tensile strength of ductile iron is 60k, while the tensile strength of Gray cast iron is only 31k.The yield strength of ductile iron is 40k,while Gray cast iron did non yield strength. The strenght and cost of ductile cast iron is much superior the Gray cast iron.Ductile cast iron and Grey Cast Iron in the corrosion resistance is in the same.   Ductile cast iron has the same strength of cast steel, but also has excellent corrosion resistance, and the cost of ductile cast iron is lower than cast steel.
