This valve is available in a type DV13A and a type DV13J design. The type DV13A is available in the control function fail safe
close and performs at a higher working pressure for standard application. The type DV13J in control function fail safe close is
mainly designed for filling applications or all other instances where the working pressure is low. One advantage of this design is a
longer diaphragm life due to less spring force. Other advantages include a very high cycle life and a smaller overall dimensionsal
height. Type DV13J is also available in control functions fail safe open and double acting for standard working pressures.
