I. Overview 
 Remote control float valve (100X), is to control the pond level of the hydraulic control valve. Promote the use of pipeline pressure upstream of the valve up, open the valve to the pool water; when the tank liquid level reaches the desired height, the float under the influence of the buoyancy increase, thus closing the valve, cut pipes to the pool of emissions. When the discharge out of the pool water, the float drop, opening the flow chamber, this time, the upstream pressure and increase the valve flap to open the valve, the piping to continue to pool water. This valve, float and prompt action, level control with high accuracy, flexible and durable, the water level is not close watertight closure pressure and interference. Mainly installed in high-rise building towers, the pool water pipe. Valve Material of main parts as follows:
