Rising stem valves have a stem that extends up when the valve is opened, while non-rising stem valves have a stem that does not move when the valve is opened or closed.

The gate is typically a flat disk that sits on top of a round seat and can be moved up or down to control the flow.

A gate valve is a type of valve that controls the flow of a liquid or gas by opening or closing a gate-like barrier inside the valve.

Gate valves are commonly used in plumbing and industrial applications, such as water and gas pipelines, and are known for their durability and ability to handle high pressure.

Gate valves are commonly used in plumbing and industrial applications, such as water and gas pipelines, and are known for their durability and ability to handle high pressure.

They can be operated manually with a hand wheel, or they can be automated with the use of actuators such as electric, pneumatic, or hydraulic.

Gate valves are known for their ability to handle high pressure and high temperature applications, and are used in a wide range of industries, including oil and gas, water treatment, power generation, and chemical processing. They are considered as one of the most common types of valves used in industrial applications.

Gate valves are typically constructed from a variety of materials such as cast iron, brass, bronze, and steel, depending on the application and the media being controlled.

The gate is typically a flat disk that sits on top of a round seat and can be moved up or down to control the flow.

They are typically not as precise as other types of valves, such as globe valves, and are not recommended for regulating flow. They are mainly used to start and stop the flow.
