Spirax Sarco VS204

Air Vent

Spirax Sarco VS204 and VS206 air vents are intended for automatic discharge of air and non-condensable gases from steam installations, helping maintain efficient heat transfer during both start-up and continuous operation. The units are supplied with threaded NPT connections in ?" and ?" sizes and are constructed with a cast iron body and stainless steel internals for durability. Typical installation points include steam main ends, distribution headers, and a wide range of steam process equipment including heat exchangers, sterilizers, jacketed vessels, and industrial heating systems.
