Specifications
HS Code:8481804090
TECHNICAL PARAMETER:
1.Application:
Double seat mix-proof valve appicatin: used for protection mixing products in brewing, dairy and drink.etc.
2.Working principle:
YF series double seat mixproff valve is controled throgh compressing air. The valve is a normallyclosed(NC) valve.
The double seat valve has 2 divided seals of valve disc. it has a interlinked cavity of leak between 2 seal at working, while it happen leaking, the products will inpour the cavity and flow away from exit. It wil not caused pollution and mixing, the leaking cavity closed while the valve working. it is impossible to overflow for the products. So the roducts can be transported from one pipe to another, also the valve can be washing CIP.
3.Material:
Steel parts: Stainless 304\316L
Sealing: EPDM. (standard)
SILICON,FDM, HNBR(CHOOSE).
4.Advantages:
-
Sealings: Excellent acid proof, alkali proof and high temperature performance. little degree of permanent compression deform.
-
Investment forging valve plug: Pressure durability less than 1.2MPA, metallographic structure beeter than casting ones.
-
Appareant design: Keep updated with international fashion style.
-
Cost performance: Impor substituted, cost saved and reiableoperation.
