5 Types of Valves Used in Boilers

Valves Used in Boilers

Boilers are essential for heating and hot water in a home or business. But have you ever wondered what goes on inside them, specifically with the valves? The valves used in boilers are critical components that ensure safe and efficient operation. In this blog post, we’ll explore the different types of valves used in boilers, how they work, and their role in the system.

Gate Valves

Gate valves are the most common type of valve used in boilers. They have a sliding gate that opens or closes to let water through, making them ideal for regulating water flow. Gate valves are also durable and easy to operate, which makes them a favourite of many boiler mechanics.

Globe Valves

A globe valve is a type of valve used in boilers to regulate the flow of hot water or steam. They have a spherical body, allowing complete shut-off with a quarter-turn. Globe valves are best suited for high-pressure systems because they handle high temperatures and pressures.

Ball Valves

A ball valve is a valve with a ball-shaped disk with a hole that controls gas or liquid flow. They are famous for boilers because they are reliable, easy to operate, and can handle high-pressure applications.

Check Valves

Check valves are crucial in boiler systems to prevent backflow. They only allow flow in one direction, preventing water or steam from flowing back into the boiler from the return lines. Check valves come in different types, including swing check valves, wafer check valves, and ball check valves.

Pressure Relief Valves

Boiler systems operate under high pressure, and it’s crucial to have an outlet valve in case of unexpected pressure buildup. A pressure relief valve is perfect for ensuring safety by releasing excess pressure automatically.


Boiler valves are integral to their safe and efficient operation. Choosing the correct valves for your boiler should be a priority to keep your system running smoothly. Ensure you learn about the different valves used in boilers and what they are best suited for. Always consult a professional when dealing with boiler valve issues to maintain your system’s integrity and ensure your building’s safety.
