ZYFLOW Automated Ball Valve

The ZYFLOW Pneumatic Spring Return Automated Ball Valve is a high-performance, quarter-turn valve solution engineered for reliable shut-off and automation in critical process environments.

​

Designed with a compact direct-mount actuator configuration, this valve ensures seamless integration, reduced mechanical losses, and enhanced operational efficiency.

The spring return mechanism provides a fail-safe function, automatically driving the valve to a predefined position during air or power failure—making it ideal for safety-critical applications.

​

Key Features & Benefits

Fail-Safe Operation

Spring return actuator ensures automatic valve positioning (fail-open or fail-close) during air or power failure, enhancing plant safety.

​

Compact Direct Mount Design

• Eliminates coupling and bracket requirements

• Improves alignment accuracy

• Reduces installation time and maintenance

Leak-Tight Performance

Precision sealing system ensures tight shut-off, minimizing leakage and process loss.
