A slab gate valve is typically used in the movement of crude oil and natural gas liquids (NGLs) through pipelines and systems. The valve is uniquely designed to produce very low friction as the crude oil or natural gas liquid passes through the valve body.
The slab gate valve can be used to open and allow the flow of the liquid, stop the flow of the liquid, or throttle or slow down the flow through the value while closing or opening rather than a fast open or close. The slab is really a single gate unit in the valve. This gate is raised and lowered between two seat rings to provide a complete seal as required.
Important Factors
The reason this gate valve is ideal for the oil and gas industry is the very low level of friction produced by the oil or gas moving through the body of the valve. This is possible due to the design, which is considered a full-port valve.
The full-port valve has a hole in the gate that is the same size as the pipe, creating no constriction through the valve body. The design of the value makes them one of the most commonly used types of gate valves in the industry. They are also used at filling stations and production and processing facilities, with the option to install these valves above the ground as well as beneath the ground.
A slab gate valve is designed to stand up to harsh environmental conditions, including exposure to crude oil, petroleum products, gasoline, and diesel fuels. These valves are low maintenance and offer long duty cycles, making them ideal for the oil and gas industry.
