Detail Information

Features of Ductile iron double eccentric butterfly valve D342X

1. The bidirectional flow double flange hard seal butterfly valve is a newly designed patented product.  It is the first application in China.
2. With the advance of Short length, small size, simple structure, high precision seal.
3. Double curve designed sealing surface. Once valve opened, sealing surface serperated, once valve closed, valve sealed. Low opening torque, easy to open and close.
4. This valve can withstand high back pressure, to avoid medium back-flow, play a role of check valve. Suitable to be installed at the exit of pump. 
5. The sealing surface adopts alloy steel, stainless steel, hard alloy, with the capacity of anti abrasive. Long Service life.
6. Resistant to high temperature and pressure, anti-corrosion

7. Manual, Pneumatic, Electric and hydraulic actuator available.

I graduated with a degree in Mechanical Design and began my career in 2012 as a QC engineer in the workshop. I worked my way up through CAD engineering and eventually served as Chief Technical Engineer. I joined Shinjo Co in 2016 and have since focused on control valves and a wide range of challenging process conditions, supporting numerous overseas clients with demanding applications. Over the years, I have come to believe that quality and solution capability are what ultimately maximize value — for both the client and the company. We welcome complex and unconventional cases. I hope my industry experience can be of help to you.
