China Butterfly Valves manufacturers Description Our common wafer butterfly valves all have four bolt holes. When installing this type of butterfly valve, you only need to use long bolts to connect the flange holes on the pipe with the bolt holes of the wafer butterfly valve. The installation and removal are very convenient, but the stability ratio is poor. The Full Lug Wafer Lug Butterfly Valve has two connection methods, because it has a through pressure hole and a threaded pressure hole. The through-type pressure hole is similar to the wafer-type butterfly valve, and the installation method is the same, but the stability is better than the clip type. The installation method of threaded hole type pressure hole is different from that of wafer type and flange type butterfly valves. Each pressure hole has a thread. The Full Lug Wafer Lug Butterfly Valve is similar to the three-piece ball valve because you can remove one end of the pipeline without affecting the other side. And you can do this by using threaded inserts, flanges, and two sets of lugs (bolts) without nuts because each flange has its bolts. Cast steel, alloy steel, stainless steel, and other materials can provide greater valve body strength and make it more durable. The smaller torque allows you to control it more easily. In addition, the two-way sealing design is safer. Materials Body : Ductile Iron (GGG40, GGG50). Cast Iron (GG25), Stainless Steel Disc : Stainless Steel.
