Among many valve products, gate valves and butterfly valves are very common valve types. However, many users do not know what the difference between the gate valve and the butterfly valve when selecting the type, and do not know how to choose these two valves. In response to this problem, the STV valve will introduce the difference between the lower gate valve and the butterfly valve to facilitate the user’s better selection. First distinguish by definition: The gate valve is one of the most common on-off valves. It is connected (opened) by means of a shutter (ie, the opening and closing member, the opening and closing member in the gate is called a gate or gate, and the gate is called a gate seat). Truncate (fully close) the media in the pipeline. It is not allowed to be used as a shut-off. During use, the gate should be prevented from being opened slightly. The erosion of the medium flowing at high speed will accelerate the damage of the sealing surface. The ram is used as a l...

Model:Z61Y-2500LB-3″ High Pressure Seal Gate Valve are designed for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service. This kind of gate valve is not only characterized as simple structure and reliable usage, but also able to create slight flexible deformation to compensate the deviation of the sealing face angle generated during processing, thus improving the process performance. In addition, at seat and gate disc seal surface are over-lay with iron-base alloy or Co-base alloy or carbide alloy for long duration. Main Parameter Specification Design and Manufacture：Cast Steel Gate Valve to API 600(ISO 10434)、API 6D;Cast Stainless Steel Gate Valve to API 603、API 600 Inspection and Te...
