The low-pressure multiway cock 7MF9004-4CA/-4DA can be flanged to pressure transmitters for differential pressure.

■Benefits

•Robust design

•For liquids and gases

•One-hand operation

■Design

The multiway cock has 2 process connections and 2 test con-

nections, which are available in 2 versions (with sealing screws G3/8 or quick-release couplings). The housing is made of hot- pressed brass CuZn39Pb3, CW 614N. Test connections with sealing screws or with self-sealing quick-release couplings.

Note: An accessory set is always required for flanging of the multiway cock to a differential pressure transmitter.

■Function

•Shutting off the differential pressure lines

•Testing the pressure transmitter zero

•Testing the pressure transmitter characteristic
