Basic information of Double Orifice Air Release Valve

This double air 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 of Double Orifice Air Valve

1. ；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 of Double Orifice Air Valve

This os & y type gate valveexhaust, 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.

Installation and Commissioning of Double Orifice Air Release Valve
