Merits and featuresBenefits and Features

Energy Conservation
Free float construction. The valve opening is under a continuous water-seal, so no steam can escape through the valve. The float’s 3-point seating holds the float tightly against the valve opening even under small condensate loads such as in superheated steam lines, so no steam is allowed to escape.
Prevention of Trouble at Start-up
The automatic air vent design opens the air vent valve at start-up to discharge the low temperature air inside the system when it is started up. This prevents the air-binding that can be caused by initial air.
Long Service Life
The high precision spherical float rotates, allowing its entire surface to function as valve sealing surfaces and thus ensuring long service life.
