Level Gauge Glass
GULF COAST GLASS level sight glasses made of STAINLESS STEEL allow for a view of the level in a tank. The valves are forged in one piece, which guarantees excellent resistance to pressure and more adverse conditions.
Gulf Coast Glass valves are the perfect choice for customers seeking durable, high-quality valves. With superior design and precise manufacturing, our valves are crafted to meet the highest industry standards. We offer a single type of valve that is versatile and suitable for a wide range of applications.
By having a single model that suits a wide range of applications, we were able to develop the most competitive valve on the market. We offer a high-quality product at a highly competitive price so customers don't have to cover indirect costs such as transportation, storage and tariffs typically associated with purchasing imported products.
As a result, our ZTV-25SS valves are well positioned with great acceptance throughout the North and South American markets. ZTV-25SS models also come with an upper vent, which allows operators to release gases or inject into the tank without the need to open it.
