Spirax Sarco 62094 VS-206 Air Vent 3/4" NPT 250 PSI Steam Service

The Spirax Sarco 62094 VS-206 is a thermostatic air vent designed for steam heating systems and process applications. This compact air vent automatically removes air and other non-condensable gases from steam systems while preventing steam loss, improving heat transfer efficiency and reducing system startup time.

Key Features:

• 3/4" NPT threaded connection for easy installation
• Maximum working pressure of 250 PSI for high-pressure steam applications
• Thermostatic element automatically opens when cool to vent air, closes when steam is present
• Stainless steel construction for corrosion resistance and long service life
• Compact design suitable for installation in tight spaces
• No external power required - operates automatically based on temperature

The VS-206 air vent is ideal for use on steam mains, headers, distribution lines, and heat exchangers where air removal is critical for efficient operation. The thermostatic element responds to temperature changes, opening to discharge air during startup and closing to prevent steam loss during normal operation. Proper air venting reduces corrosion, eliminates air binding, and ensures uniform heat distribution throughout the steam system.
