Basic information

This double orifice air release valveis a pipeline will be matched equipment, apply to the temperature does not exceed 100 water, hot water pipe on the pipe from the air.

Features

1. Body is provided with a shock-proof inner tube to protect the float;

2. Lower water pressure can be closed to prevent drainage;

3. When there is negative pressure, the piston quickly opens to breathe;

4. Stainless steel floating ball, long life.

Principle

This valve exhaust, buoy, by gravity pull down one end of the lever, the lever in the tilt state at this moment, in the leverage and vent contact appeared gap, air through the vent through the gap, with the air discharge, water level rise, buoy under the effect of the buoyancy of water float upwards, the lever on the seal face pressure on the porosity, gradually until the vent is completely blocked. The exhaust valve is now completely closed.
