VALVES / CONTROL VALVE
ELECTRICALLY OPERATED GLASS CONTROL VALVE-6600 SERIES

Electrical actuated Glass control Valves for controlling Flow of Acid in an Acid Regeneration Plant specially used in Pickling Plant to recycle waste Acid.

Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminium alloys. A solution called pickle liquor, which contains strong acids (typically hydrochloric or sulphuric acid) is used at about 80°C, and they are used to remove the surface impurities.

Waste from pickling process which mainly consists of hydrochloric sulphuric acid, Suspended Iron particles & Water along with CNG and Air is feed to a reactor in controlled manner through motorised Glass Valve. This acid gets converted to gaseous form in the reactor which is again converted to acid in an absorption column.

The Glass valve is made of Borosilicate Glass Type 3.3 as per BS-2598 guidelines equivalent to International Standards & PTFE plugs. Glass valve allows visual checking to monitor Flow of acid and see that crystallization does not take place. The valve has to be washed periodically with water to remove iron particles if any.
