Detail Information
H44N Brass Swing Check Valves for Oxygen is applicable to oxygen pipe network systems worked as one-way valve, playing a role of cuuting off and check, such as preventing cold air backflow in the oxygen system and the mixture of nitrogen and oxygen inthe slag furnace.
The product consists of body, bonnet, disc, etc. The medium enters from one side and makes the disc rising, medium flow; when the medium pressure loses or outlet pressure is greater than inlet pressure, the disc drops automaticly to close the channel, works as check effect. The main parts materials selects silicon brass, with a good fire retardant properties.

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.
