Product Overview
The Stainless Steel Electric Ball Valve is an industrial automation control valve designed for reliable shut-off and precise flow regulation in demanding process environments.
It integrates a corrosion-resistant stainless steel ball valve with an intelligent electric actuator, enabling remote operation, automated process control, and seamless integration into PLC, DCS, and SCADA systems.
The product is engineered for continuous-duty industrial applications where safety, stability, and long service life are required.

Engineering Calculation Reference
Valve Sizing Reference
Flow capacity is determined using Cv/Kv calculation:
- Kv = Q / √ΔP
- Cv = 1.156 × Kv
Torque Selection Principle
Actuator torque is affected by:
- Differential pressure
- Seat material friction
- Fluid type (liquid / gas / slurry)
- Valve size (DN)
