Steam boilers can have several types of valves, all working in one way or another to control the path of steam and heated water in homes and businesses. They’re essential safety equipment that govern pressure and temperatures.
Here’s a quick rundown on common valves in steam boilers:
These valves are very adaptable and flexible, making them common fixtures in boilers. An actuator turns a rod holding the butterfly valve to handle the flow.
Also called disc check valves, non-return valves allow the flow to go in one direction only; they stop the flow if it changes direction. The disc check valves most in use are the life check valve, swing check valve, spring-loaded check valve, and diaphragm check valve.
Just as its name implies, the gate valve uses a metal gate to allow or block the flow.
A hollow ball is used to close or open the valve.
They come in conical or cylindrical shapes, opening and closing as desired.
These are used for flow that is traveling in a S formation.
