What type of valve is suitable for water vapor containing dust?
Thread Content
For dry gas with a temperature of 140 degrees, a pressure of 3 KPa, and a dust content of 100 mg/m3, which type of valve is appropriate? The pipe diameter is DN600.
If you want the valve to last longer, I recommend using a double-eccentric butterfly valve. If you want to save costs, I recommend a center-line butt-welded butterfly valve with a spherical valve body, a 304 valve disc, and a PTFE seat.
