Low-pressure multiway cocks производства Siemens

• Robust design
• For liquids and gases
• One-hand operation

The multiway cock has 2 process connections and 2 test connections, 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.
