Product Description 

The hydraulic counterweight butterfly valve is composed of butterfly valve body, hydraulic by-pass valve, heavy hammer, release device, manual oil pump (or electric oil pump), rack drive oil cylinder and electronic control. The pressure oil of the oil pump is input into the rack drive cylinder, and the gear on the main shaft of the butterfly plate is rotated by the upper rack of the piston to open the butterfly plate, and the weight on the coaxial shaft is lifted to a high point. The pawl on the weight hammer is locked by the spindle shaft on the release device; the spindle shaft is fixed and controlled by an electromagnet and a supporting device. When the accident occurs, due to the action of the electronic control part, the electromagnet is cut off, the lock spindle shaft is out of control, and the butterfly valve is automatically closed by releasing and rotating around the shaft under the weight of the heavy hammer.
