Bardiani BBZS5 Single Seat Valve

The BBZS1 and BBZS5 by-pass valves, brought to you by Saniquip, have been designed to be highly versatile and are suitable for different types of application across many industrial sectors.
Regulation of the retained pressure depends on the loading of the spring in the heart of the valve. This load can be regulated by adjusting the ring nut, located inside the protective casing on BBZS1, or by using the adjustment pin on the back of the actuator on BBZS5, with the option to facilitate valve washing by opening the actuator with air injection.
