Bell & Gossett Adds New Automatic Purge Valve to Sediment Removal Separator

ITT Bell & Gossett has introduced a new SRS Pneumatic Purge Valve that workswith Bell & Gossett's Sediment Removal Separator (SRS). This valve dischargessediment collected from open and closed loop systems in applications involvinghydronic heating, process and cooling tower systems.

Used to remove undissolved sediment as well as air, the centrifugal-typeSRS separates out abrasives that can damage pump seals, plate heat exchangersurfaces and other system components, as well as hinder heat transfer efficiency.The SRS unit collects sediment in the bottom of the vessel where it is discharged.

The SRS Pneumatically Actuated Diaphragm Purge Valve regularly dischargesthe sediment into drainage systems. It is controlled and operated by a programmabletimer. This eliminates the need for manual purging or the chance of excesssediment collecting in the SRS vessel.

By removing sediment and abrasives from systems, the SRS and the new purgevalve prolong the operating lives of other system components and reducemaintenance and down-time by preventing the fouling of spray nozzles, valves,controls, gauges and even erosion of the piping system or heat exchanger.By eliminating sediment build-up in heat exchangers, the SRS and purge valveunits can make hydronic systems more energy-efficient.

Compared to similar models on the market, Bell & Gossett's SRS offers severaladvantages, including a pressure drop through the unit that is two to threetimes lower than competing units. This uses less pump energy and often permitsSRS installation on the pump suction side, thus protecting this importantcomponent. Competitors' models require the location to be on the pump dischargeside.

The SRS design also provides system air separation and elimination not offeredby competing units. This is especially beneficial in cooling tower systemswhere air entrainment can be a problem.
