Sewage Air Release Valve With Anti Shock Function Prevent Water Hammer Without Spill

 

Description:

 

    In waste water system , additional gas will accumulate because of all kinds of gas or air to ventilate the waste water. In order to minimize the headloss, SKAR - sewage air release valve is very important to be installed for venting the air in pipeline. Air release takes place at high points, on long ascending and descending pipe sections, downstream of pumps, upstream of restrictions.

​​

   Sewage air release valve with anti-shock device can help to prevent water hammer so that can minimize headloss. It decreased the water velocity and restrict the velocity of air flow. This type of valve is generally used in long sewage water transmission pipeline where may have water hammer. If the air exhaust out the valve too quick, the waste water will comes in very fast, too. The water will prevent the float go up which caused the valve leaking.

 

Function:

 

Combination kinetic air release valve provide 3 functions:

 

1. Large air release -

Anti shock device to prevent fast flow and water hammer. Decrease the air exhausting velocity to prevent water hammer. Slow down water and air out with multi holes on top sealing arc

 

2. Small air release

When operation the air produced by the pipeline is accumulated in the upper part. Little by little it is compressed and its volume increases, pushing the liquid level downwards and allowing the air release through the small nozzle.

 

3. Large air intake during draining of the pipeline.

During pipeline draining, or pipe bursts, it is necessary to bring in as much air as the quantity of outflowing liquid. This is to avoid bad pressure and strong damages to the pipeline and the total system

 

 

Features:

 

Without spilling.

.  Wider middle body, shorter height.
Slow down the flow velocity, keep sewage in the body.

Drain boss at the top & bottom for cleaning.

.  Fully fusion epoxy coated inside and outside of valve body for long term services.
• Most parts of valves can be recycled.
• Float with a rubber sealing can be as an absorber to prohibit water hammer direct acting on the sealing arc and seat impact.
• All internal parts are 316SS without rusting.

For sewage water system.
