Set up in 1995, China Deland Valves Manufactring Co.,Ltd. is one of the leading float valve manufacturer, supplier and distributor in Yongjia County of Zhejiang Province. We manufacture all float valves strictly conforming to the API, JIS, ANSI, BS, GB, NF and DIN standards. Our float valves are available to users on request and are used for municipal works, petroleum, chemical industry, power station, metallurgy, national defense, and scientific research fields. We can supply custom, used, discount, cheap float valve and accessory to USA, UK, Canda, Amercia, Europe, Germany, France, Japan, India, Iran, Russia, Poland and more than 30 countries in the world.

	It is composed of valve body, valve seat, diaphragm, springs, valve bonnet and etc. It is controlled by float valve and adjusted with the pressure difference between the above and below diaphragm. When the pressure water that has entered control cell below the diaphragm is drained to the low pressure area, pressure on the bottom of the valve and below the diaphragm is greater than that on the above diaphragm,thus the valve seat is pushed to fully-open position and water flows in. When water on above the diaphragm is not able to be drained to low pressure area, pressure on above the diaphragm is greater than that on below the diaphragm, thus pushing the valve seat to fully-closed position and stop water from flowing in.
	Diaphragm type remote control float valve is a hydrauliclly-operated valve with much function. It is installed at the inlet of spool or water tower. When the water level reach to the setting, the main controlled by the pilot valve, close and stop supply water; when the water level falls downward, the main valve controlled by the pilot valve, opens and supplies water to the spool. The water level is controlled precisely and is not interfered by the water pressure. Floating ball remote control valve can be installed freely according to the spool's height and use spaces. It is easy to maintain and to inspect the valve. The valve is liable,of high strength and of smooth action and is DN450 or less valve.The valves can be used to automatically fill troughs, tanks and ponds.Both valves work under normal mains pressure.
	Normal pressure: 1.6MPa Working medium: cold & hot water, gas fuel, oil, etc. Working temperature: Between -20 degrees and 150 degrees. Thread standard: 55 inches system pipe thread. Float valves and lever valves are designed to control the level of liquids through mechanically actuation. Float valves are actuated through the attached float ball, float rod, and lever assembly and do not require any external power source. Lever valves are actuated through the use of some external power source such as manual operation, float boxes/mechanisms, electric motors or other actuators, through external linkage to the lever of the valve. It is one of the most advanced valves in China. It can precisely control water level. Control water level regardless of water pressure. Perfect seal without any leakage and close and open nimbly and with good duration. It is mainly used in the automatic water control system of water towers and tanks as well as some special sector such as oil store.
