Piping
Use the product within the specified operating pressure range and temperature range.
Proof pressure is 2.25 MPa.
Connect the piping to the fittings.
Mount the product so that the fluid direction is the same as the arrow indicated on the product.
Never mount the product upside down.
The piping on the IN side must have a straight section of piping whose length is 8 times the piping
diameter or more.
Avoid sudden changes in the piping size on the IN side of the product.
●
Connecting the piping
Ensure that the metal piping attachments are tightened to the required torque (refer to the table below).
If the tightening torque is exceeded, the product can be broken. If the tightening torque is insufficient, the
fittings may become loose.
When connecting piping to the product, a spanner should be used on the metal piping attachment only.
Using a spanner on other parts may damage the product.
Avoid any sealing tape from entering inside the piping.
Ensure that there is no leakage from loose piping.
