一、STRUCTURE AND PURPOSS
Installed on inted of a water pool or tower.The mian valve is controlled by the floating pilot vavle to close the inlet to stop water supply when the water level gets to the set height and to open the inlet to supply water to the water tower or pool so as to realize the automatic water supplement when the water level lowers.It features a high accuracy of level control ,water pressure disturbance resising,mountable on any positions,reliable seal performance,easy installation,miantenance,debugging and check,long duration(The floating pilot valve can be separately from the main one).
二、 FEATURE
1. Tightly and reliably closed.Use of secure O-ring seal and hydraulic control principle makes the closing force of the sliding disk proportional to water in pressure,leaving a high reliability of the seal.
2. Big flow.The valve body is so designed as the full-path stream-line type,causing a small fluid resistance and a big flow.
3.Saft running.Use of hydraulic operation can automatically control the level of the water pool or tower very accurately.
4.Easy use and maintenance.Installation outside of the water pool of the main valve makes debugging and checking easy and maintenance simple.
