Ball Valve

Ball Valve

A ball valve controls flow by adjusting the opening of a spherical element. It forms a tight seal with the seat for zero or minimal leakage, and operates with a quick 90° turn. The full-bore design ensures low pressure loss, while its compact size suits space-constrained or modular systems. Ideal for tight shutoff and emergency stop applications.

20S Series Actuator

The 20S electric ball valve actuator supports a wide voltage range from DC 5V to AC 220V. Compact in size, it delivers up to 70,000 cycles with a fast 2-second open/close response. Certified with CE and ISO 9001, it passes insulation and dielectric tests to ensure safe, stable operation. Rated IP67 for water and dust protection, and available in a moisture-resistant version for humid or low-temperature environments. Features flexible wiring, easy installation, low noise, and maintenance-free performance.

Optional Handwheel

Optional Handwheel

The actuator comes in two versions: handwheel (S) for manual override, and non-handwheel (SJ) for fully automatic electric operation.
■ Handwheel Operation Instructions 
1. Manual operation must be performed with power off. To operate, lift the manual override button and slowly turn the handwheel to the desired valve position.  
2. In the indicator window, the red line parallel to the pipeline indicates "open", while perpendicular indicates "closed."

Applications

■ Industrial automation equipment and instrumentation
■ Smart water-saving controllers and system actuators
■ Environmental protection, low flow rate, water supply and drainage, and water treatment projects
