What is the application of PTFE lined butterfly valve?

PTFE lined type butterfly valve is one type of central lined butterfly valve, which is one normal type of butterfly valve in need of big quantity. PTFE lined butterfly valve is mounted between two matching flanges of the piping with bolts and nuts. According to actual piping conditions, PTFE lined type butterfly valve can be manufactured according to different flanges standards.

What are the benefits that PTFE lined butterfly valve brings to us/

PTFE lined butterfly valve is small in size and light in weight. In comparison with traditional ball valves and gate valves, butterfly valves save at least 70% of space and weight.

PTFE lined butterfly valve is easy to install and maintain. PTFE lined butterfly valve can be mounted wherever needed.

PTFE lined butterfly valve has simple and compact construction, which can on-off quickly at 90 degrees.

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.

PTFE lined butterfly valve has less torque. The pressure on disc at the two sides of spindle is almost equal, causing contrary torque. Thereby, the PTFE lined butterfly valves can be opened with less force.

What is the application of PTFE lined butterfly valve?

PTFE lined butterfly valves are used in a number of applications for industrial sectors that include food processing, pharmaceutical, chemical, oil, water as well as waste water management. The PTFE lined butterfly valves utilized in these industries are generally manufactured in compliance with the Pharmaceutical Quality/Manufacturing Standard, CGMP (current good manufacturing practice) guidelines. PTFE lined butterfly valves for the most part have replaced ball valves in a lot of industries. This is especially the case for those dealing with petroleum because PTFE lined butterfly valves are less expensive and easy to install. It's important to note that pipelines that contain PTFE lined butterfly valves cannot be pigged for cleaning.

In throttling, regulating control and mud medium, the structure length is required to be short and the opening and closing speed is fast. For low pressure cut-off with small pressure difference, it is recommended to use a PTFE lined butterfly valve.

When the PTFE lined butterfly valve is used under special conditions such as throttling adjustment, strict sealing requirements, severe wear, and low temperature, the triple-eccentric or double-eccentric butterfly valve needs a specially designed metal sealing belt adjustment device.

How to choose PTFE lined butterfly valve?

Determine the nature of the fluid in the pipeline, whether it is liquid, gas, or solid; whether it is neutral, corrosive, viscous, suspended particles, vacuum, high pressure, or powder. Then determine whether the function of the PTFE lined butterfly valve requires only opening and closing, or whether it requires to control the flow accurately, or needs to reverse the flow.

From a functional point of view, PTFE lined butterfly valves are more suitable for pipelines that need to control flow. PTFE lined butterfly valves are more suitable for open or closed pipelines because the flow path is straight, with small flow resistance and rapid opening and closing.

From the nature of the fluid medium, PTFE lined butterfly valve has a simple structure, opens and closes quickly, which is suitable for a variety of media, including media with suspended particles and powdered media. But PTFE lined butterfly valve is not suitable for high temperature, high pressure and high tightness requirements. The flow rate adjustment range of PTFE lined butterfly valve is small.

Learn more something about PTFE lined butterfly valve can know the applications of PTFE lined butterfly valve and how to choose 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.
