DZ23 / DZ24 are fitting for connection and commissioning of differential pressure transmitters of the series DS11, DE16, DE38 und DE39. In a block casing there are three valve components with which the measuring lines can be blocked on the process side and pressure can be compensated on the transmitter side. The DZ24 is additionally equipped with a vent valve for the pressure lines and the valve set. The valves should have metal seals. The valve spindles contain rotating ball bearings that form a wear-free seal to the block casing. The valve spindles are sealed to the outside with O-rings. The hand wheels can be lead-sealed or detached for safety purposes.
