What is the role of valves in boilers?
Thread Content
What type of valves are generally suitable for installation on boilers?
1. Valves used in boilers include, mainly, gate valves, globe valves, ball valves, safety valves, needle valves, butterfly valves, and check valves. 2. The water system of boilers mainly uses medium to large-diameter gate valves. 3. The steam system primarily uses globe valves (forged). 4. The ventilation and flue gas systems mainly use butterfly valves. 5. Safety valves are installed throughout the system to ensure safe system pressure. 6. All pressure gauges are equipped with needle valves. 7. Check valves are installed in most pipelines to ensure maintenance accessibility and one-way flow. 8. Among various pressure levels, gate valves and check valves that are used in large quantities in boiler systems generally operate at pressures below 4.0 MPa, while globe valves generally operate at pressures above 10.0 MPa
