Check valve is used in stainless steel pipe system to prevent reverse flow.
- The valve opens when the pressure below the valve plug exceeds the pressure above the plug plus spring force
- The valve close when pressure equalization has been achieved
- A higher counter pressure will press the valve plug against the seat and makes the valve sclosed
- Material Contact Parts:304 or 316L
- Sealing material:EPDM
- To assure the connection and substitution with imported facilities, all the connection styles with pipe or equipment are made to DIN 11850,IDF/ISO,SMS international standard size.
Required differential pressures to turn on the valve that fitted in a vertical pipeline are about:
- Max.Pressure for transfer material:10bar
