Product Description

HS41X antifouling isolation valve is a kind of valve which is installed in all kinds of pipeline systems to strictly check the medium and to protect thelater medium or equipment from pollution. Two series of check valves and tr ansition partsThe components are tightly sealed to ensure no backflow, safeand reliable, and long service life. This product is mainly used for drinking water supply system in high-rise buildings, fire fighting water system and airconditioning refrigeration, water plant water supply pipeline and other systems use.

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.
