5. Installation 

 

5.1 Precaution for installation 

 

          Caution 

1.  Before

 

connecting the product in the piping, be sure to remove foreign substances and scale from the 

piping. 
*

 

Failure  to  follow  this  notice causes valve  seat  leakage  due  to  the  ingress  of  foreign  substances and 

scale into the product. 

2.  To install the product, check the direction of the product so that the fluid flowing and the arrow marked on 

the product are in the same direction. 
*

 

Wrong direction prevents fluid from flowing. 

3.  Connect  the  product  to  the  piping  so  that  excessive  load,  torque  or  vibration  cannot  be  applied  to  the 

product. Be sure to connect the product to piping firmly. 
*

 

Failure to follow this notice may cause fluid leakage and result in burns or property damage. 

4.  On installation, align center part of the product with that of flange by making fin-shaped part contact with 

bolt as indicated in the figure below. 
 

 
 
 
 
 
 

 
 
 

 

 

6. Operating procedure 

 

6.1 Precaution for operating procedure 

 

          Caution 

Before leading fluid, make sure that there is no danger when the fluid flows to the end of piping. 
* If tightening is not secured, hot fluid may spout out and result in burns. 
* Fluid outflow may cause property damage.
