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, 60 g for conduit terminal type respectively. �� Refer to “Glossary of Terms” on page 139 for details on minimum operating pressure differential, the maximum operating pressure differential, maximum system pressure.
