What are the features of PTFE lined butterfly valve?

PTFE lined butterfly valve has small size with light weight.

PTFE lined butterfly valve is easy to operate and install.

Elastic seal of PTFE lined butterfly valve is produced by torque.

The unique design of three-way eccentricity of PTFE lined butterfly valve enables frictionless transmission between the sealing surfaces and prolongs the service life of the PTFE lined butterfly valve.

The wedge-shaped design makes the PTFE lined butterfly valve have an automatic sealing function that is closer and tighter. The sealing surface has compensation and zero leakage.

The PTFE lined butterfly valve can be equipped with pneumatic and electric devices according to user requirements to meet the needs of remote control and program control.

Compared to ball valve and gate valve, PTFE lined butterfly valve is great energy saver with lesser torque operations.

PTFE lined butterfly valve has stable anti-corrosion performance because of bubble-tight sealing resulting to no leakage under the pressure testing.

PTFE lined butterfly valve has wide selection of material, such as DI, carbon steel, stainless steel, super duplex, or alloy material. All are applicable to various mediums.


What is the technology of PTFE lined butterfly valve?

The biggest feature of the PTFE lined butterfly valve is that the flow surface is covered with fluoroplastics to isolate the direct contact between steel and strong corrosive media. PTFE lined butterfly valve solves the problem of not only low strength of fluoroplastics and cannot withstand high pressure, but also steel materials that are not resistant to corrosion and rationally utilizes resources, conforming to the national energy-saving and consumption-reducing industrial policy. PTFE lined butterfly valve has developed rapidly. In the production of PTFE lined butterfly valves, the most important thing is to select suitable fluoroplastic raw materials and formulate reasonable lining technology, as well as mold design.

Molding is one of the fluoroplastic process methods, which is also the most commonly used method for PTFE lined butterfly valves. It is suitable for a variety of small batch production methods. It is to put a certain amount of fluoroplastics into the molded cavity. Then close it, heat it to a certain temperature in a heating furnace, which melts and flows under pressure, slowly filling the entire cavity to obtain the shape given by the cavity .


How about the development of PTFE lined butterfly valve in the future?

PTFE lined butterfly valves are mechanical devices specially designed to direct, start, stop, mix or regulating the flow, pressure of a process fluid. A PTFE lined butterfly valve typically consists of a metal disk formed around a central shaft, which acts as its axis of rotation. As the PTFE lined butterfly valve's opening angle is increased from 0 degrees (fully closed) to 90 degrees (fully open), fluid is able to more readily flow past the PTFE lined butterfly valve. These PTFE lined butterfly valves are commonly used to control fluid flow inside of piping systems.


The global butterfly valves market size is expected to reach $13,667.0 million by 2025 from $8,282.61 million in 2017. PTFE lined butterfly valve is a shut-off valve used to isolate and control the flow of fluid and gases in various industrial applications. The PTFE lined butterfly valve industry is an important branch of our general machinery. PTFE lined butterfly valves are widely used in petroleum, chemical, metallurgy, electric power, urban construction, environmental protection and other industries as key equipment for fluid control. At present, the PTFE lined butterfly valve production industry is in a very favorable development opportunity.


Learn more something about PTFE lined butterfly valve can know the features of PTFE lined butterfly valve and the technology of PTFE lined butterfly valve. In the process of butterfly valve development, a number of very powerful companies have emerged, such as Tianjin Worlds Valve Co., Ltd.
