PRODUCT CATEGORIES DESCRIPTION

What Are Stop Valves?

Stop valves, also known as isolation valves or shut-off valves, are a type of valve used to control the flow of fluid in a pipeline. They are commonly used in industrial and commercial applications where the need for precise control of fluid flow is essential.

What Is The Structural Feature Of The Stop Valve?

The structure of a stop valve consists of a valve body, bonnet, stem, disc, and seat. The valve body contains the fluid passage and the disc is connected to the stem which controls the opening and closing of the valve. The seat is the sealing surface that prevents fluid from leaking past the valve when it is closed.

What Is The Principle Of The Stop Valve?

The working principle of a stop valve is based on the use of a disc that is moved up and down by the stem. When the valve is open, the disc is lifted away from the seat, allowing fluid to flow through the valve. When the valve is closed, the disc is pushed down onto the seat, sealing off the flow of fluid.

What Are The Main Connection Types And Sizes Of Stop Valves?

Stop valves can be connected to pipelines using a variety of methods, including threaded, flanged, or welded connections. They come in a range of sizes, with common dimensions ranging from 1/2 inch to 24 inches in diameter.

What Are The Main Applications Of Stop Valves?

Stop valves are commonly used in applications where precise control of fluid flow is necessary, such as in industrial processes, water treatment plants, and HVAC systems. They are also used in emergency situations where the flow of fluid needs to be quickly shut off in order to prevent damage or safety hazards.
