Spring valve: In a spring valve the opening is controlled by a spring. There are two commonly used types: pressure relief and excess flow.

Plug valve: A plug valve is similar to a ball valve in that it has a hole in the center that can be aligned with the pipe to allow gas flow, or it can be turned one quarter of a turn to block flow. The difference from a ball valve is that a plug valve has a cylindrical or conical shape.

Ball valves are used throughout the gas delivery system. They are used for blocking or directing flow in the transmission system and at the customer meter to allow service to be turned on and off.

Like ball valves, plug valves are used throughout the gas delivery system for blocking and directing flow on the transmission system and as customer service valves. Due to maintenance and operation factors, many older plug valves in gas systems are being replaced with ball valves.

Gate valves are used throughout the gas distribution system. They are used to control flow on distribution feeders as well as inlets to regulator stations and customer service pipes.

Spring-operated pressure relief valves are often used at regulator stations to ensure that downstream pressures do not exceed maximum allowable operating pressures in the event of regulator failure.

Ball valve: A ball valve contains a ball with a hole in the center. If the hole is aligned with the pipe, gas will flow through the valve. But if the valve is turned one quarter of a turn, the ball will block flow through the pipe.

Valves perform various functions throughout the gas delivery system. They block flow by not allowing gas to pass beyond a certain point. Valves isolate pressure by separating two sections of the system that operate at different pressures. They direct flow by determining what path is open for gas to flow. Valves also manage pressure by partially blocking a specific path resulting in a downstream drop in pressure. Different types of valves are used for different functions and are differentiated by how they control flow.

Gate valve: A gate valve contains a gate that is lowered into the pipe to stop flow or raised out of the pipe to allow flow to pass. Gate valves require several turns of the handle to fully open or close the valve.
