What are the commonly used materials for valve electric devices?
To select the correct valve material, the engineer must consider the flow media, pressure, flow rate, and intended purpose, while the temperature of the flowing medium and the operating environment are factors that need to be considered for the valve material. Corrosion can occur at higher temperatures. In addition, temperature can cause different materials to expand and contract at different rates, which can cause leakage problems, excessive restraint stress on valve elements, or failure episodes.
Components such as valve actuators, valve seats and valve bodies are usually provided in materials that provide different ranges of corrosion, temperature and wear resistance. Commonly used materials include:
Ductile iron: Due to its low cost and availability, ductile iron provides the additional benefit of easy shock absorption. The downside is that ductile iron has poor corrosion resistance.
Brass and Bronze: Brass and bronze valves are also available at low cost and are readily available. Increased corrosion resistance compared to ductile iron.
3.316 stainless steel: known for its excellent corrosion resistance, 316 stainless steel valves are more expensive than cast iron, brass and bronze valves.
4. Monel alloy: nickel-copper alloy Monel has excellent corrosion resistance. It is usually used for the covering of valve trim.
5. Inconel nickel alloy: Inconel is an alloy of nickel, chromium and iron, used to deal with corrosive media at higher temperatures.

How to install electric gate valve?
When using equipment, scientific installation is required. If the installation method is wrong, then the performance of the equipment is difficult to reflect, but also may cause harm to the equipment, so how to install the electric gate valve. In the installation of electric gate valve, the need to do the following, to be able to reflect its own value. First of all, before installing the gate valve, you need to read the installation instructions. If you do not read the relevant instructions when installing the gate valve, but only rely on the so-called experience and awareness to install, it is likely to make mistakes in installation. Shangzhou valve to remind the majority of users, electric gate valve installation needs to have a certain direction, need to pay attention to some details, if the installation of gate valve, need to use glue, then need to go through a period of maintenance, can be used. Therefore, when installing the electric gate valve, don't think how to install it, just blindly install it. Before safety, it is very important to learn the relevant installation knowledge.
What are the advantages of automatic control ball valve?
The automatic control ball valve is widely used in many fields, and it is naturally inseparable from its unique advantages. This kind of ball valve has the following excellent advantages: Advantage 1: The automatic control ball valve has good weather resistance. The automatic control valve can still maintain good working efficiency in various complex environments. Naturally, it is inseparable from the high temperature resistance, low temperature resistance, acid and alkali resistance of the automatic control valve. Therefore, the application range and field of this ball valve are relatively broad. Support the development of the national economy. Advantage 2: The working stability of the automatic control ball valve is high. After countless experiments, the Shangzhou valve continuously improves the working stability of the automatic control ball valve. Therefore, the ball valve provided by the company can support the stable and sustainable production of the enterprise. Advantage three: high precision, automatic control ball valve in the research and development, with high scientific and technological content, optimize material selection, optimize the internal design and focus on experiments, so that it has a high degree of precision, which is of great value for promoting the development of green economy.
What is the difference between globe valve and gate valve?
The valve is a control component in the fluid delivery system, with the functions of cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems, from the most simple cut-off valve to a very complex automatic control system used in a variety of valves, its varieties and specifications quite a wide range. Globe valves, gate valves, butterfly valves, check valves and ball valves, etc. These valves are now indispensable control components in various piping systems. Each valve is different in appearance, structure and even functional use. However, there are some similarities between the cut-off valve and the gate valve in appearance, and both have the function of cutting off in the pipeline. Therefore, there will be many friends who have little contact with the valve to confuse the two. In fact, if you look closely, the difference between the globe valve and the gate valve is quite large.
