ANSI Or BS Standard Triple Function Ductile Iron Combination Air Release Valve

Description:

1. Large air release

1-1. During filling the pipeline, float will stay at its original position. (open)

1-2. Let large air out of valve thru big nozzle.

2. Small air release

2-1. When the water level comes up to the top, float will be up to its close position and close the sealing arc- big orifice and small orifice.

2-2. The air (2% of solved air in water ) are continuously coming out from water and gather at the top of the valve.

2-3. The float will be driven down and let small pocket out thru small orifice.

2-4. The sealing arc will still be in close position until empty of water

3. Large air intake during draining of the pipeline.

3-1. Float will drop down when empty of pipeline.

3-2. Large air will come into the pipeline thru valve.

3-3. Preventing from collapse of pipeline and break vacuum.

3-4. Protect the sealing o-ring from clogging in the pipeline.

Features:

. Advanced design: Simple mechanism and strong float to prevent cracking during sudden water hammer& quick close.
. No levers to prevent vibrating, bending, direct closure of the float.
. Smooth cage outside of the float, keep float moving in specifi ed guide rail.
. Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage during vacuum.
. Outside screen is for safety and prevent insects in.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Manufacturing standard : BS EN1074-4, AWWA C512
. Flange drilling and dimension : BS EN 1092 and BS EN 558 and ANSI flange.
