butterfly valve with gear box

Simple in structure, small in volume, light in weight, saving material, small in equipment size, small in driven torque, convient and quick in operation, excellent in adjusting flow rate, upstanding in sealing. It can be said that butterfly valve has been one of the fastest developing valves for the past years. Small in flow resistence when fully opened. Between the angle 15 to 70, it aslo can be controlled flexcibly. In the heavy carlible adjusting field, it is widely used.Friction caused by movement of valve disc, so most butterfly valve can be used in the suspendid solid particles medium and mealiness and paticales medium based on the sealing strength.
