Fischer pressure transmitter Misc. / accessories DZ68 | Three-spindle compensating and shut-off valve for DA30

Fitting for connection and commissioning of differential pressure transmitters of the series DE01.
Design and mode of operation 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 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.
