What are the characteristics and applications of ventilation butterfly valves

In many industrial production, ventilation butterfly valves are commonly used equipment, but outsiders are not very familiar with them. Just the name is the first time I have heard of it, let alone what kind of equipment it is. Below, we will introduce it from two major aspects: its characteristics and uses. Firstly, let's talk about the characteristics of ventilation butterfly valves. They have a simple structure, are a regulating valve, and are non enclosed butterfly valves that can be used for switching control of low-pressure pipeline media. From the perspective of structural form, the advanced design of welding the centerline plate and short structural steel plate is adopted, which is not only very compact, but also lightweight, easy to install, low resistance, and relatively large flow rate. It can still be used smoothly under high temperature conditions. From its internal perspective, there are no connecting rods or bolts, ensuring long-term use and multi station installation. Let's take a look at its usage. As a non enclosed butterfly valve, it has been used in many industrial production industries, such as building materials, power, metallurgy, etc. It can transport various media. The temperature is below 300 degrees, and the nominal pressure is 0.1Mpa on pipelines, playing a role in connecting, opening, or adjusting the media quality. Simply put, it is a switch control device. In terms of sealing for ventilation butterfly valves, the materials used are rubber, polytetrafluoroethylene, etc., which can work in general situations, but are not suitable for industries such as high temperature, high pressure, corrosion resistance, and wear resistance. However, compared to traditional butterfly valves, this device is simpler to operate and has a high temperature resistance effect. It has no friction when opening or closing, and is usually safe to use for a long time. It can be selected according to needs.
