Specifications
HS Code: 8481804090
TECHNICAL PARAMETER:
1. Application:
Double seat mix-proof valve application: Used for protection mixing products in brewing, dairy and drink. Etc.
2. Working principle:
YF series double seat mix proof valve is controlled through compressing air. The valve is a normally-closed(NC) valve.
The double seat valve has 2 divided seals of the valve disc. It has an interlinked cavity of a leak between 2 seals at working, while it happens to leak, the products will inpour the cavity and flow away from the exit. It will not be caused by pollution and mixing, the leaking cavity closed while the valve working. It is impossible to overflow for the products. So the products 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. A little degree of permanent compression deforms.
Investment forging valve plug: Pressure durability less than 1.2MPA, metallographic structure better than casting ones.
Apparent design: Keep updated with international fashion style.
Cost performance: Impor substituted, cost saved and reliable operation.
5. Connection types:
Welded.
Clamped
Screw or threaded
Welded - crew
Flange
To assure the connection and substitution with imported facilities, all the connection styles withe pipe or equipment are made to DN11850, IDF / ISO, SMS 3A international standard size.
