DFH20/7 Mine natural safety electric ball valve

Introduction of DFH20/7 mine intrinsic safety type electric ball valve

Dfh20/7 mine safety type electric ball valve is a new type electric valve which can be opened and closed by the rotation of the ball. It is suitable for the place with wide range of water supply pressure and not affected by sediment and sewage. The water supply size is large, the power supply time is short in the working process, the working stability is reliable, it is a kind of general solenoid valve ideal substitute product.

Dfh20/7 Mine safety type electric ball valve product features

The electric ball valve is a new type of electric valve which rotates by the ball and opens and closes the waterway. The IN end is the external control signal to control the opening and closing of the ball valve. The direction control circuit detects the working position of the ball valve. The working status indicator circuit indicates the working status of the ball valve: the ball valve rotates and opens, and the green LED is bright. The yellow light is on when the aperture is opened. When IN is high, the ball valve rotates to close, and when the close is IN place, the red light will be on.
