A combination non return/magnetically controlled valves used primarily for non magnetisable pipe-work and pref. for in-and outlet-spouts of soda-water siphon heads. Sipohon heads of this kind are complete with valve, actuating lever and charge/discharge spout (22). The combination non-return/magnetic drive valve (1) placed in the spout is complete with valve-seat (3) and a magnetisable swing-back valve flap (4), arranged to be open toward the direction of the work's medium flow and shut in the opposite direction. |
