*

Concerning the allowable pressure for each temperature, material and actuator type, see the technicaldocuments at the next page of this sheet.

*The diaphragm may become loose due to temperature changes during long storage, operation stop or
while in use. Check the conditions and then retighten the bolts and nut between the bonnet and the bodyto the "bonnet tightening torque". (Failure to do so may cause fluid leakage.)

In addition to the standard product, the following options are also available according to your requirements.

For corrosive fluid transport lines, we offer
PVDF cushion cover accessories having
excellent gas barrier performance toprevent deterioration due to permeation ofgas from the diaphragm.

DIAPHRAGM INSERTED METAL (STAINLESS STEEL)

For chlorine gas lines in electrolysis plants,
we offer electrolytic options using highly
corrosion resistant special metal to prevent
corrosion of inserted diaphragm fittings.
