Ultra Clean has been granted a patent for a valve that controls fluid flow. The valve includes a valve body, a valve stem with a control portion and a tail portion, a deformable valve seat, and a ring. The valve seat is deformed by a nut pressing onto it, creating a sealed space between the valve stem and the valve body.

A recently granted patent (Publication Number: US11680647B2) describes a valve for controlling fluid flow. The valve includes a valve body with an internal cavity and a valve stem that can block the fluid flow. The valve stem has a control portion for blocking the flow and a tail portion for transferring rotational torque. The control portion and tail portion have different diameters.

The valve also includes a deformable valve seat that is carried by the control portion in a conformal manner. A ring is mountable within the internal cavity, and a nut is used to secure the ring in place. When the nut is secured to the valve body, it presses onto the deformable valve seat, causing it to deform and fill a space between the middle portion of the valve stem and the valve body in a sealed manner.

In one embodiment, the outer surface of the control portion and the internal surface of the valve seat are cylindrical. The valve seat can be formed by machining, and it can be made of a polymeric material such as PEEK, PCTFE, PTFE, reinforced PTFE, modified PTFE, PFA, or any combination thereof.

Additionally, the valve includes a disc that can be seated between the valve stem and the valve body to prevent direct mechanical contact.

This patented valve design offers a unique solution for controlling fluid flow. The use of a deformable valve seat allows for a sealed connection between the valve stem and the valve body, preventing any leakage. The choice of polymeric materials for the valve seat provides durability and resistance to various fluids. The inclusion of a disc further enhances the functionality of the valve by preventing direct mechanical contact, reducing wear and tear.

Overall, this patented valve design presents an innovative approach to fluid flow control, offering improved performance and reliability in various applications.
