OPERATION PRINCIPLES:
The valve open when the pressure of the fluid exceeds the pressure to spring, when the two pressure are equalised,the valve close.A stronger counter pressure also makes the valve close.

1.Vertical and horizontal design
2.No dead space and crevices
3.Fits to sanitary stainless steel tubing
4.FDA-approved elastomer materials: EPDM, Silicone, (FPM).
5.Sanitary surface finish, available with Ra < 0.4µm or EP (SF1 and SF4)
6.A wide selection of different end connections

Application:
Check valve is for prevents the fluid from flowing back and ensures to flow in only one direction.
It can be used to prevent the flow less from returning avoid pipe hammering.
It is used in the food processing, beverage,wine,oil,cosmetics,pharmaceutical and chemical industries.

| HOW DO WE MAKE THE QUALITY CONTROL | |
| For Raw Materials |
1. Material control from raw materials. For raw material checking, we check 100% by chemical liquid. Any property mistakes would be rejected. 2. Sand hole inspection after raw materials are machining before polishing. 3. Carbon component report can be provided if needed 4. Mechanics test report can be provided if needed |
| For New products | 5. 2nos of new samples to be checked against technical drawing. Testing report is provided to customers before bulk production. |
For finished materials |
6. For valves, pressure testing and temperature testing is required for each valve. 7. After we get the finished products, we check for surface roughness, thickness equality, roundness, size measurement and sand holes again. 8. For all finished products, the checking quantity is not less than 10% of total quantity. 9. Before shipment, we check for the quantity of each product in order to find out any missing quantity or wrong product. |
