Product Description

Structural features and uses

This series of flange type butterfly valves adopts a center-weighted straight plate design. The main valve consists of an integral vulcanized rubber seal covering the inner cavity valve body and the butterfly plate. A handle or worm gear transmission device is selected to control the handle or worm gear to rotate 90" to achieve the function of opening and closing the valve. Its main features are: short structure length, light weight, and rapid opening and closing. Small installation space: rubber material is resistant to aging and corrosion, and the number of opening and closing times exceeds 8,000 times: bidirectional sealing, and the use is not affected by the direction of water flow. The flow characteristics tend to be linear and the adjustment performance is good: the handle or worm gear transmission can self-lock at any valve opening to meet the functional requirements of regulating water flow.
