Spirotop Air Release Valve (Spirotherm# VTP050) is specifically designed to efficiently eliminate larger size air bubbles which may occur on system's first start-up or after maintenance. It eliminates the need to manually bleed hard-to-reach areas, such as the tops of risers, tanks, unit heaters, and horizontal lines near the ceiling.


Spirotop’s low profile and high-compression valve combine to give a leak-resistant, high point vent that fits just about anywhere. Spirotop resists dirt particles and sudden pressure changes, which may cause ordinary air vents to leak. Whether filling or draining a system, venting high points, or eliminating air locks, Spirotop is the solution.
