Main Feature:
It is opened or closed by the valve clack moving to-and-fro through the valve body guiding axle under the spring effect.
The valve body passageway is designed in a wing-shaped streamline type, allowing the medium to flow through the passageway rapidly and steadily with no noise.
It can be installed on horizontal and vertical pipelines.
