716 - Regal Gas Sulphonators - Auto Switchover

The REGAL Model 716 Automatic Switchover Gas Sulphonator is a totally vacuum-operated system which is designed to automatically switch the sulfur dioxide feed from an empty cylinder to a full cylinder. It is also designed to provide systembackup. Should a problem develop with either vacuum regulator, sulphonation 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 tubes with maximum capacities of 4, 10, 25, 50 and 100 pounds per 24 hrs. of sulfur dioxide gas with corresponding metric scales of 75, 200, 500, 900 and 2000 grams per 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.
