∆P = Minimum Opening Differential Pressure; PMO = Maximum Operating Pressure; TMO =
Maximum Operating Temperature
NOTE: - PMO,TMO may vary according to the options selected. Check nameplate, drawing, etc.
- When the valve has remained closed for a long period of time, the valve and the valve seat
may stick, increasing the necessary minimum opening differential pressure. Make sure to
open the valve properly before the installation.
In addition, the minimum opening differential pressure varies depending on the direction of
flow due to the influence of the weight of the valve disc. See the table on the next page.

PTFE = Fluorine Resin
Perfect sealing cannot be guaranteed for metal or PTFE sealing surfaces.
*
4
NBR = Nitrile Rubber; FPM = Fluorine Rubber
For rubber sealing surfaces, a closing differential pressure of more than 0.05 MPa (7 psi) will be
required for perfect sealing. (However, degradation of, or debris on, the rubber sealing surface may
prevent perfect sealing.)
