Piping - SMC Networks PF2A7 Series Operation Manual

■Piping

Use the product within the specified operating pressure range and temperature range.
Proof pressure is 1.0 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.
