DIN 11850 Stainless Steel Threaded Butterfly Valve

 

This valve is sanitary, automatic or manual handle valve, widely used in food, beer, beverage, dairy products, cosmetic, pharmacy and biology engineering field.

 

Working principle:

The valve is mechanically locked in its 4 positions of open or close through four multi-functional positioning rod manual operation. It can control the flow of the medium

 

 

Material:

Steel parts:      Stainless 304\316L
Sealing:           EPDM. (standard)

                       SILICON, FDM, HNBR(CHOOSE).

 

 

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.
