Are there corrosion-resistant steam valves?
Thread Content
I would like to ask the experts: are there any corrosion-resistant steam valves? My application involves using steam to heat wastewater containing chloride ions. Since the process is intermittent, the valve is exposed to both steam and wastewater at the same time. Is there a suitable valve for this purpose? Thank you
Hard-sealed butterfly valves can be used; their advantage is high temperature resistance, and the sealing mechanism is corrosion-resistant
Is a butterfly valve reliable for use with steam? Steam is usually controlled by a globe valve
Fluorinated check valves are resistant to chloride ion corrosion, but they are sensitive to temperature and pressure. What are the temperature and pressure levels in your case?
Low-pressure steam, generally not exceeding 0.5 MPa
The pressure is fine; it can be used as long as the temperature does not exceed 120 degrees
Is this one for direct heating, or heat exchange via a partition?
Go straight with steam, but it will come into contact with corrosive wastewater containing chloride ions
