Detail Information
G41 Cast iron ptfe diaphragm valve
Diaphragm valve is one special cut-off valve; Compared to other valve, diaphragm valve are equipped with below fetures:
1. No leakage inside due to the elastic seal;
2. Streamlined runner and small pressure loss
3. No need of packing, then no outward leakage
4. Parts above the diaphragm such as bonnet, stem, etc can not be eroded by medium, for the diaphragm cut off the connection between medium and bonnet.
5. Replaceable diaphragm and low maintenance cost
6. Various lining materials to choose for different medium, and good anti-corrosive.

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.
