Vatac Hydraulic Butterfly Valve is a kind of tailor-made products, as it can be different combination with butterfly valve and control system. The basic valve is designed to be automatically closed by gravity closing devices, and opened by electric and hydraulic actuator.

When it was used at the discharge side of pump, it is a kind of pump control valve as it has two stage of valve opening and closing (quick 85%+15% slow adjustable) to avoid water hammer damage and protecting pipe system. When it was used at the inlet of turbine, it is a kind of emergency shut-off valve, close the valve within a very short time and prevent turbine reaching its runaway speed.
