Frequently Asked Questions (FAQ)
This motorized wafer butterfly valve is manufactured in strict compliance with the EN593 international standard for industrial valves.
The standard temperature range is -20°C < T < 120°C. Specific working temperature limits depend on the selected seat material (e.g., EPDM, NBR, VITON, or PTFE).
The valve uses a high-quality, flexible soft-sealing elastomer structure that adapts to minor pipeline deviations and pressure fluctuations, guaranteeing reliable bidirectional zero leakage.
The ultra-thin wafer structure reduces total valve weight and size, saving installation space, lowering pipeline loading, and significantly reducing construction and shipping costs.
Yes, the installed electric actuator supports both local operation and automated remote control, including precise on/off switching and proportional modulating control.
