BBZS1 and BBZS5 series by-pass valves are suitable for various types of applications and for various industrial sectors. Control of the pressure maintained depends on the stress exerted upon the spring in the heart of the valve. This stress can be controlled by adjusting the ring nut in the protective casing on the BBZS1. The BBZS5 series is provided with an air motor which permits adjustment and control of the pressure.
