Description
The REGAL Model 750/756 Sulphonator is a vacuum-operated, solution feed type, designed for mounting directly on a sulfur dioxide cylinder valve by means of a positive heavy duty yoke clamp. The sulfur dioxide flow rate is manually adjusted and is regulated by a spring opposed diaphragm regulator which also contains the safety shut-off valve. Vacuum is provided by a highly efficient water operated ejector which is close coupled with the sulfur dioxide solution diffuser. The ejector assembly contains a back flow check valve.
