I. Overview 
 YQ98005 electric float valve piston filter installed in the main pool or the elevated water tower water inlet, when the water level reaches the set height, the main control valve is closed by the float pilot valve to stop water supply intake; when the water level, the main valve controlled by the float pilot valve opens to the pool water intake, automatic replenishment. Precise level control, free from pressure interference; diaphragm type remote control float valve to the height of the pool and with the use of space anywhere in the installation, maintenance, commissioning, inspection convenience, long service life. Reliable, high strength, smooth operation. Closed tight and reliable, with streamlined body design, fluid resistance, flow rate; to use and maintain, the main valve installed in the pool outside, easy to debug inspection and maintenance simple. Material of main parts as follows: 

 Part Name Material 
 Body, bonnet cast iron, cast steel, stainless steel 
 Bronze seat, stainless steel 
 Valve carbon steel, stainless steel + nitrile rubber 
 Qinggang aluminum stem, chrome stainless steel 
 Chromium stainless steel + nitrile rubber piston 
 Stainless steel filter 
 Stainless steel spring 

 Second, characteristics: 

 1, closed tight and reliable. With a strong Q-ring seal, the use of hydraulic control theory, the sliding plate off and the water pressure is proportional to, sealing and high reliability. 
 2, over flows. Streamlined design with full channel body, fluid resistance, flow rate. 
 3, operational safety. Use of hydraulic operation, automatic control tower or tank liquid level, liquid level control accuracy. 
 4, easy maintenance. Outside main valve installed in the pool, commissioning inspection easy and simple maintenance.
