Small butterfly valves are usually made in sizes from 1 to 24 inches.

Butterfly valves are usually made of carbon steel, austenitic stainless steel, stainless steel, duplex stainless steel, titanium alloys, nickel alloys and nickel aluminum alloys.

Principles of butterfly valve operation The operation of this valve is similar to the operation of the ball valve, which enables immediate closing of the valve.

Butterfly valves are popular because they have a low price compared to other valve designs, and their lower weight also means that they need less support.

The disc is in the center of the tube.

A rod passes through the disc and connects to an actuator system outside the valve.

With the rotation of the driver, the disc also rotates parallel or perpendicular to the flow.

Unlike a ball valve, this disc is always in flow, so it creates a pressure drop even when it is open.

A butterfly lion belongs to the family of lions called quartered lions.

In operation, this valve is either fully open or fully closed when the disc rotates a quarter turn.

The meaning of the propeller is the disk that is installed on the rod.

When the valve is closed, the disk rotates to completely block the passage.

When the valve is fully open, the disc rotates a quarter turn to allow fluid to flow through the passage almost unrestricted.

Maybe the valve can be opened step by step so that the flow is established as a pressure breaker.

There are different types of butterfly valves, each of which is suitable for different pressures and applications.

The non-offset butterfly valve has the lowest pressure rate by using rubber flexibility.

Double offset butterfly valve, high performance used in relatively high pressure installations, has a center line of the seat of the disc and the body of the sealed washer and the center line of the hole.

This type creates a cam action during operation which causes the seat to be removed from the sealed gasket and reduces friction to zero compared to the offset design, thus reducing wear.

The valve that is mostly used in high pressure installations is the three-offset butterfly valve.

In this valve, the contact axis of the disc seat is the offset, which completely eliminates the sliding contact between the disc and the seat.

The seat of the three-offset valves is metal, so it can be machined to create a leak-free state when contacting the disc.

Types of butterfly valves A butterfly valve rotates in a quarter turn to stop, start, or regulate flow.

Butterfly valves are of the immediate opening type.

A 90 degree turn of the handle can fully open or close the valve.

Normally, these valves are used in systems where there is no need for an absolute breaker.
