Features
1. Tightly and reliably closed. use of secure O-ring seal and hydraulic control principe makes the closing force of the sliding disk proportional tothe water-in pressure, leaving a high reliadility of the seal.
2. Big flow.The valve body is so designed as the full- path streamline type,causing a small fluid resistance and a big flow.
3. Saft running.Use of hydr aulic oper ation can automatically control the levelof 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.
