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

Application of Electric Brass Ball Valve

HVAC system, heating system, Water treatment system, Industrial equipment

Operational mode of Electric Brass Ball Valve

motorized ball valve is motor-operated by a type of WRA-63…, and WRA-63…A actuator. The actuator is controlled by a modulating on/off or 3-point control system and move the ball of the valve, to the opening position dictated by the control signal.
