Product Description

A cryogenic ball valve is a specialized type of valve designed to handle extremely low temperatures, typically below -150°C (-238°F). It consists of a spherical closure element (the "ball") with a hole through its center. When the valve is open, the hole aligns with the pipe to allow fluid flow, and when closed, the ball rotates to block the flow.

These valves are constructed with materials that can withstand the extreme temperatures and maintain their integrity, such as stainless steel or other alloys. They often feature extended stems and additional insulation to prevent freezing of the valve components.

Cryogenic ball valves are commonly used in industries like liquefied natural gas (LNG) processing, aerospace, and medical applications where cryogenic fluids are handled. They are crucial for ensuring safe and efficient operation in these low-temperature environments.

 

One advantage of a cryogenic ball valve is its ability to maintain tight sealing even in extremely low temperatures. The design of the ball valve allows for reliable shut-off and control of flow, even in cryogenic applications where temperatures are well below freezing.
Additionally, cryogenic ball valves are often constructed with materials and components that can withstand the harsh conditions of cryogenic environments, ensuring durability and longevity of the valve.

They Utilize a hollow ball that rotates allowing a flow through it when aligned and stops the flow when it is in a closed position. A quick 90 Degree turn of the handle is all that is needed to fully open or close the valve flow.

 When the handle is parallel and in-line with the pipe, then the valve is open. When the handle is perpendicular and at right angles to the pipe, then the valve is closed. It is this 90° turn either clock wise or anti-clockwise to open or shut the flow of the valve ,that led them to also be known as quarter-turn valves.

The valve has an internal rotary ball with a hollow bore running through the center. This Inner ball is connected to the handle via a stem. So by turning the handle the ball rotates and when the hollow bore is aligned with the pipe and the in same direction as the flow, then the flow is open, and when the bore is perpendicular to the flow, then flow is shut off.
