brief introduction

In addition to the advantages of elastic seat seal gate valve, the special signal gate valve for fire protection can directly display the opening degree of the valve, so as to judge the opening degree of the valve at a distance and take corresponding measures in time. Groove connection can improve the speed of pipeline installation and disassembly, save time, and achieve the effect of fast, convenient, safe and firm. This kind of gate valve opens and closes quickly and reliably, so it is often used in fire fighting system.
