Superior - Model SD-2 Series - Gas Sulfonator - Brochure

The SUPERIOR™ Series SD-2/5 Gas Sulfonator is a state-of-the-art, vacuum-operated, solution feed type which mounts directly on a sulphur dioxide valve. The Sulfonator is mounted onto the sulphur dioxide valve of a cylinder, wall manifold or ton container adaptor, using a very heavy-duty, positive yoke clamp connection. A sulphur dioxide gas flow meter panel indicates the amount of sulphur dioxide being fed and may be located wherever it is safest and most convenient. Sulphur dioxide flow rate is manually adjusted and the design permits easy addition of a number of automatic flow rate control devices. A high efficiency, water operated ejector produces the vacuum necessary to operate the system. The ejector assembly contains a back-flow check valve system to prevent pressurized water from entering the Sulfonator. A spring-opposed diaphragm vacuum  regulator controls the sulphur dioxide gas flow rate and also acts as the safety shut-off valve
