GNB Corporation designs and produces a range of specialty vacuum products, including a wide variety of vacuum valves for widely ranging applications.
Here’s a quick tour of where our company has gone in designing world-class vacuum products in recent years.
Through excellence in design and attention to detail, we are proud to offer the K-style valve. GNB Corporation has shipped this product all around the world where they are running millions of cycles without a single issue.
Our customers may be surprised by how inexpensive this valve is, given its high-quality performance and design.
Here’s another compact valve with the only difference being a smaller size than the one pictured above.
GNB Corporation makes these valves from ISO 50 to ISO 500 sizes.
The next example may look like a pendulum valve. However, it doesn’t fit that category because of its linear-moving gate. Per specifications, this one needed to have a small footprint with compact packaging. This was the reason for its unique design.
The customization had an additional requirement: a rigid valve. It couldn’t move, shift, or have any deflection with cantilevered weight hung off the valve flange.
A million-dollar piece of optics was inserted through the middle of the valve. As it moved in and out of the opening, the valve’s precision allowed it to move without any deflection whatsoever.
Sizing specifications are important. No matter what the size, GNB Corporation delivers a range of specialty vacuum products that are free of contaminants and leaks of any kind.
Our reputation around the world revolves around our capacity to construct large-gate valves. Because of the trust in our products, any space simulation facility will likely be equipped with GNB’s gate valves.
The 10 gate vales below, for instance, were used by NASA’s Plum Brook Station, the world’s largest thermal-vacuum test chamber.
In this photo, you see GNB Corporation’s founder Gary Norman Burnett inside a gate valve many years ago.
Similarly, I was photographed in an updated gate valve, a legacy product here at GNB Corporation.
We have a history of making valves so large, you can literally walk through them.
For the metallurgical industry, GNB Corporation furnished this design with a guard ring that protects against splattering and possible contamination of the valve and sealing surface.
The next photo demonstrates our excellence in design, production and attention to detail even when faced with complex problems.
This valve posed some engineering challenges. On the right, there’s a curve gate valve. It seals against the curved surface of the chamber and can flex over to seal a vacuum tight in either direction.
On the left, this valve has hatches and access ports. It is also hydraulically operated for easy cleaning and servicing.
GNB Corporation is also known for creating a wide variety of angle vales, in every shape and size, for every industry, including semiconductor, metallurgy or heat treatment.
Finally, we also have a line of ball valves, pictured below. These are doing great in the industry and are available to all of our customers.
Our strong reputation relies on our ability to work alongside customers no matter their industry or technical requirements. We design and create a wide range of products that will always be everything our customers want and need them to be.
