The Butterfly Valve in the Industrial World

Jun 10, 2021 Blog

Simply put, a valve is a device that detects the flow of any substance, from gases to fluidized solids, to all types of liquids to suspensions. Typically, these devices regulate the flow of the substance by opening, closing, or partially blocking various channels.

A butterfly valve is something like a flow control device that is usually used to allow a certain fluid to flow through a certain part of a pipe. This valve is similar to a ball valve. Various types of a butterfly valve(which is also known as วาล์วผีเสื้อ in the Thai language ) with a flat circular plate are located in the centre of the pipe and the steam is passed through the plate and attached to the handle on the outside of the valve.

Butterfly valves come in three different types. Typical dual eccentric high-performance throttle valve operates at pressures up to 725 PSI. The second type is the tough butterfly valve, which has a flexible rubber seat. This type operates under pressure up to 232 PSI. The last type is the pericentric throttle valve, which is usually designed with a metal seat. This valve operates at pressures up to 1450 PSI.


Various types of butterfly valves are also available in the market. Waffle valves will be the most common because the person ordering them won’t even say the word “waffle,” but they still have the valve they want.
