Signal gate valve and signal butterfly valve are often used in automatic sprinkler system to monitor water supply pipeline and control valve opening remotely. Rising stem gate valve and attached opening indicating gate valve are also often used in fire fighting system. If the installation position of the gate valve is higher than the ground, the rising stem gate valve is generally used to indicate the valve opening. If the installation is low, the attached opening indication gate valve is required.
1. Overall rubber coating: the soft seal gate valve adopts the whole rubber coating, which has good covering performance and accurate geometric size to ensure reliable sealing and service life.
2. Light weight: the valve body is made of nodular iron, light in weight and easy to install.
3. Flat bottom valve seat: the same flat bottom valve seat design as the water pipe is adopted at the bottom, which does not produce debris deposition, and the sealing is more reliable.
4. Corrosion resistance: the inner cavity of the gate valve is coated with non-toxic epoxy resin to prevent corrosion and rust. It can be used not only for drinking but also for sewage system.
5. Three "0" seal: the valve rod is sealed with three 0-rings, with small friction resistance, light switch and no water leakage.
