What is the name given to the shut-off valve installed on all lateral branch piping from a main or riser?

The shut-off valve installed on all lateral branch piping from a main or riser is known as a service valve. This valve is essential in a medical gas system as it allows for isolation of specific sections of the gas distribution system for maintenance and service without disrupting the entire facility’s gas supply.

Service valves are strategically placed to ensure that during repairs or modifications, the flow of medical gases can be halted in a controlled manner, minimizing potential risks to patients and maintaining safety protocols. By using service valves, healthcare facilities can efficiently manage their gas systems and ensure compliance with safety standards.

In contrast, while terms like zone valve, branch valve, and main valve may seem relevant, they refer to different components or functions within a medical gas system. Zone valves, for example, are typically used to control the gas flow to a specific zone or area within a facility, whereas branch valves might pertain to the connections from the main pipeline to various branches but are not specifically for lateral piping. Understanding the specific role of a service valve highlights its importance in effective medical gas management.
