Cautions for use of the products 

 
 
 

1.  Use the products within the specification range of the working conditions such as medium, working 

temperature/pressure and so on. 

 
 
 
 
 

1.  Confirm the fluid compatibility with the wetted part of the products in the "Suitability List on Medium"   

in the latest Dymatrix general catalogue (AV-V-029-EJ). (Parts may be damaged by a kind of a 
medium.) Consult us on any medium, which is not listed in "Suitability List on Medium".   
Moreover, if you intend to use it with compressed air or gas (such as air, nitrogen, ozone,   
or other gas), we do not assume product liability of the Product. 

2.  Cavitations could be generated depending on the working condition. If cavitations are observed,   

review the fluid pressure and piping design. 

3.  Do not use the valve in negative pressure. (It can be damaged.) 
4.  Handle the products carefully to protect the clean (room) packaging. 
5.  Use CDA (Clean Dry Air) for pilot air, which does not contain any organic solvents or   

corrosive gases. 

6.

 

Confirm the flow direction of the valve matches the flow direction indication on the body.

 

 
 

Cautions for maintenance

 

 
 

1.  Discharge the fluid and the pilot air prior to the maintenance. 
2.  Start maintenance after medium has been completely flushed by DI Water or air. 
3.  Do not disassemble the product. Disassembled products which may cause them to not keep their 

original specifications or performance.   
We cannot guarantee a disassembled product. 

4.  Check the piping periodically to maintain the appropriate condition for the products.
