What are the functions of PTFE lined butterfly valve?

A high-performance PTFE lined butterfly valve is a quarter-turn valve best suited for handling large amounts of liquids or gases. PTFE lined butterfly valves are easy to handle and are used in many flow control and throttling applications. The PTFE lined butterfly valve can only be fully opened and fully closed and cannot be adjusted or throttled. The flange butterfly valve has two sealing surfaces.

PTFE lined type butterfly valves use bolt length, which is equal to standard bolt length plus nut length plus butterfly valve thickness plus spring pad thickness plus flat pad thickness and a little margin. Generally, the bolt length is calculated according to the matching flange. The bolt hole of the PTFE lined butterfly valve is matched with the thread and is installed by a full-threaded stud bolt. One of the nuts is removed, the bolt is twisted into the bolt hole of the PTFE lined butterfly valve, and then the nut is tightened.

There are two holes on the PTFE lined butterfly valve. There are also through holes and internal threads. If it is a through hole, the bolt will grow long and pass through. The function of PTFE lined butterfly valve is to position the valve pipe coaxially when it is installed. Simply put, it is convenient to install with these holes. The PTFE lined butterfly valve is tightened by bolting the two flanges together to produce a clamping force. The caveat here is that a flange has eight holes but the valve does not have to have eight holes. Generally speaking, there are four holes and two holes. Internal threads, short bolts, installed on both sides of the valve.

What are the functions of PTFE lined butterfly valve?

The PTFE lined butterfly valve is mainly used in industrial production pipelines. The function of PTFE lined butterfly valves is mainly to cut off the flow of the medium in the pipeline, or to adjust the size of the medium flow in the pipeline. PTFE lined butterfly valves are widely used in production pipelines in general industries such as water conservancy engineering, water treatment, petroleum, chemical, and urban heating. PTFE lined butterfly valves can also be used in condensers and cooling water systems of thermal power stations.

PTFE lined butterfly valve is to retain a seal to protect against dual-directional pressure differential in the flow of fluid. In other words, the wafer version of PTFE lined butterfly valves was designed to hold a tight seal, safeguarding against bi-directional pressure differential in order to avoid any backflow in systems that have been manufactured for uni-directional flow. This is accomplished by using a tightly fitted seal, such as an O-ring, precision machined, along with a flat valve face on the downstream and upstream sections of the PTFE lined butterfly valve.

What is the working principle of PTFE lined butterfly valve?

The PTFE lined butterfly valve operates based on the quick shut off principle. The circular disc (butterfly) of the PTFE lined butterfly valve is placed in the center of the pipe which allows a rod to go through it to an actuator, on the outer side of the PTFE lined butterfly valve. Using the handwheel, the metal disc is rotated to keep the disc parallel or perpendicular to the flow and it allows or closes the flow. So, the operating principle of the PTFE lined butterfly valves is fairly simple.

The PTFE lined butterfly valve is one of the few industrial valves that are both efficient in isolating and regulating the flow of media. The PTFE lined butterfly valve is also quick to open. The disc is attached to the stem, either through the former or the stem is at the back of the disc. The stem is attached to the handle that is either placed on top of the body or at its side.

The disc of PTFE lined butterfly valve is thin in the middle. Together with the seat, it seals off the flow of media when the PTFE lined butterfly valve is used for isolation. For the control of flow, the disc moves to partially open or close, allowing a certain amount to pass through.
