SKAR - Sewage Combination Air Release Valve

How do we ensure finished product quality (FQC inspection)

1. Visual Inspection

2. Material Grade Measurement

3. Dimension Inspection

4. Roughness Detection

5. Roughness Detection

6. Leakage Test

Surface Treatment

We offer the following processes to choose:

1. Mechanical Polishing (MP) to improve brightness (gloss, matte)

2. Acid Cleaning for Anti-corrosion

3. Electrolysis Polish (EP) to improve surface smoothness

4. Custom Process: Bright Annealing treatment eliminate strees to improve toughness

Combination kinetic air release valve provide 3 functions:

1. Large air release during fi lling of the pipeline.

2. Small air release under pressurized pipeline.
3. Large air intake during draining of the pipeline.

. Advanced design with simple mechanism, strong fl oat to prevent cracking during sudden water hammer& quick closure.

.  Window cage for upper stablizing
. No arms or levers to prevent vibrating, bending, direct closure of the float.

. Drain boss at the top & bottom for cleaning
. Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage during vacuum.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Manufacturing standard meets BS EN1074-4, AWWA C512
