Válvula de paso recto eléctrica con volante
Electric Globe Control Valve With Handwheel is a pressure balance regulating valve. It adopts a cage sleeve guide and a single seat sealing structure. This electric globe control valve is equipped with an electric actuator,and the flow passage is S-streamline and the quality seal ring is used.The cage guided single seated electric globe control valve has the characteristics of stable operation, large allowed differential pressure,accurate flow characteristics and low noise. It is especially suitable for work situations where the pressure difference between the upstream and the downstream is large.
