FAQ'S

What type of valve is best suited for steam applications?

Ball valves, globe valves, and gate valves are commonly used in steam systems. However, globe valves are preferred for control, while steam-rated ball valves offer quick shut-off in on/off applications.

Can I use a standard ball valve for steam?

Not recommended. Steam requires specially designed ball valves with high-temperature seals (often metal or graphite) and steam-rated bodies to ensure safe, reliable operation under pressure and heat.

What temperature and pressure ratings should I look for?

Steam valves should typically withstand temperatures up to 200–450°C and pressures up to 40 bar, depending on the application. Always check the valve’s specific steam rating to ensure compatibility.

What materials are suitable for steam valve construction?

Stainless steel, carbon steel, and bronze are commonly used. Internal components and seats may be made from metal, PTFE, or reinforced graphite for high-temperature resilience.

Do I need a specific seat type for steam ball valves?

Yes. Metal-seated or reinforced soft-seated valves are ideal. Standard PTFE seats may deform under high heat, so opt for steam-rated materials like graphite or PEEK.

What maintenance is required for steam valves?

Regular checks for seal wear, pressure leaks, and corrosion are crucial. Valves in steam systems should be inspected periodically and serviced with compatible steam-rated spares to ensure longevity and safety.
