What type of control valve is most effective for blackwater or graywater pipelines?
Thread Content
In the gasification units of the water-coal slurry gasification process, both black water and gray water contain certain particles, which cause significant wear on valves, especially control valves. Could you please explain what types and materials of control valves are used in each gasification unit?
Regulating valve for black water discharge at the bottom of the scrubber tower; operating pressure: 6.27 MPa; operating temperature: 243°C; normal flow rate: 43,977 Kg/h. Valve type: single-seat angle valve; valve core and seat material: 316L with WC coating; leakage class: ANSI Class IV
Beijing Aerospace Petrochemical Technology Equipment Engineering Company has the appropriate black water control valves; you can refer to them!
