756 - Regal Gas Sulphonators - Auto Switchover

The REGAL Model 756 Automatic Switchover Gas Sulphonator is a totally vacuum- operated system which is designed to automatically switch the sulfur dioxide feed from an empty sulfur dioxide supply to a full sulfur dioxide supply. It is also designed to provide system-backup. Should a problem develop with either vacuum regulator, sulphonator can be continued.

FEATURES

ë System Back-up Ä Each cylinder's sulphonator has its own vacuum regulating diaphragm and safety/inlet valve insuring that sulphonation can be continued if service should be required on either sulphonator.

ë Corrosion-resistant, Factory-adjusted Detent Mechanism Ä Detent does not require any field adjustment assuring that cylinder switchover will occur at the proper time, and that all available gas in supply cylinder will be used.

ë In-Use/Stand-by Indication Ä Prominent indicator on face quickly tells which is the stand-by cylinder and which cylinder is in use. Optional flowmeter panels are available for applications where the feed rate must be known at the sulphonator and the flow meter/rate valve panel cannot be seen.

CAPACITIES

Dual scale metering tube with maximum capacity of 500 pounds per 24 hrs. of sulfur dioxide gas with corresponding metric scale of 10kg/hr.

FLOW RATE ADJUSTMENT

Manually adjustable by means of a flow rate control valve located at the top of the flow meter. Flow rate is then regulated by a special spring-opposed diaphragm operated valve. The system is automatic. It will go off and on as the ejector water is turned off and on and will always return to the pre-set flow rate.

* All systems are supplied with high pressure ejectors.
* If low or hi/low ejectors are required, please contact us for pricing.
