Note 1) Be aware that even if the pressure difference is above the minimum operating pressure differential when the valve is closed, the pressure difference
may fall below the minimum operating pressure differential when the valve opens, depending on the power of the supply source (pumps,
compressors, etc.) or the type of pipe restrictions.
Note 2) Weight of grommet type. Add 10 g for conduit type, 30 g for DIN terminal type, 60 g for conduit terminal type respectively.
Note 3) If you need a valve for air of C37 (Brass) or SUS (Stainless steel) in the port size of 1/4, use the valve for water.
Refer to “Glossary of Terms” on page 33 for details on minimum operating pressure differential, the maximum operating pressure differential, maximum
system pressure.
