Product Description

Pn10/Pn16 Worm Gear Double Flanged Manufacturers Rubber Seated Butterfly Valve

Pn10/Pn16 refers to the pressure rating of the valve, which is 10 or 16 bar. Worm gear double flange rubber seat butterfly valve is an industrial valve used to control the flow of various fluids such as water, oil, gas and chemicals. It consists of a rubber-lined disc that rotates inside the pipe to control the flow of fluid. The valve is operated by a worm gear mechanism that allows precise control of the valve position. The double flange design facilitates installation and removal of the valve on the piping system. The rubber seat provides a tight seal when the valve is closed preventing any leakage.
