The differences between the new model 2023 diaphragm valve and the old diaphragm valve
The difference is in the installation of the diaphragm gasket; the old one has threads, which has high requirement for mounting it can not be too tight or too loose. The new model 2023 diaphragm can avoid this problem & with longer working life
The new diaphragm valve’s height will be a little higher than old model.

The new model of installation of the diaphragm gasket. We rotate the diaphragm by 90 degrees

Old diaphragm installation is below which has screw on the gasket , the screw must be in place

New model diaphragm installation is below , install the diaphragm into the disc and rotate with diaphragm by 90 degree without thread , it will be more easy without leaking

If there is any future question pls feel free contact DONJOY, Thanks for attention .
