Who can select and manufacture pneumatic control valves for high temperature, high pressure conditions, with a large diameter of DN450? Urgent, the sooner the better! !
Thread Content
A flow control valve is required for medium-pressure steam at a temperature of 425 degrees℃； Inlet pressure: 4.5 MPa (g) ； Exit pressure: 4.48 MPa(g) ； Flow rate: MAX: 220 t/h, NOR: 150 t/h ； The pressure difference before and after the control valve is: 0.02 MPa ； Viscosity: 0.025cp ； Pipe specification: Φ480X20. Pipe material: 20G. Those who can carry out the calculation, selection, and manufacturing please contact me at PJZHM@126.COM
The valve selected is the CV 8800 DN/DG 450; the manufacturer is Wuxi Gongzhuang. The name of the valve is 710E High-Performance Butterfly Valve (Double Eccentric Type). The pressure rating is ANSI 300#. The flow characteristic is equal percentage. Additional data: units are imperial. CV values (maximum/normal/minimum): 4796.37, 3270.25, 2515.58. Opening degree (maximum/normal/minimum) (%): 82.2, 70.9, 63.2. I’m just doing the calculations for you: lol
Agree with the person above; there should be no problem. This post was last edited by backhamm1982 on 2009-2-23 14:49.]
