Sanitary Check Valve(YZ)
Application:
This type ofcheckvalveis used in the stainless steel piping systern to achieve the purpose ofpreventing backflowoffluid.
Working principle
Check valve is a valve on the flow of the medium itself automatically open and close the valve. when the pressure exceeds the lower part of the valve stem yalve stem above the pressure and spring force when the check valve opens; when under pressure balance valve stern when the valve is closed, so as to achieve the medium one-way flow in pipeline the liquid, prevent backflow, preventaccidents.
Material :
Steel components: stainless steel304,
stainless steel316L.
Sealing ring: silicone rubber (VMQ)
fluorine rubber(FPM) three yuan (EPDM)
