Selection of steam valves
Thread Content
I specialize in equipment, and I’m not sure how to choose valves; the client doesn’t understand this either. A globe valve should be installed at the start of the steam pipeline, with a control valve placed later to regulate the pressure. A shut-off valve should be installed first at the outlet, followed by a steam trap. Please help determine the appropriate model. Thank you. The pipe specification is DN80; the operating pressure is 0.09 MPa, while the equipment pressure is 1.2 MPa
Piston valves work very well for steam, as they do not leak.
Do you use electric or pneumatic power? A standard single-seat control valve will suffice for the regulating valve; the valve body should be made of WCB, and it’s sufficient if the valve body can withstand a pressure of 16 kilograms. If you have any questions, feel free to reach out! QQ: 928976489 (Your control valve consultant). 13764138562 – MR GUO
Stop valves and pressure reducers are simple; the stop valves and steam traps at the outlet should be selected based on the amount of steam required. A filter should be installed between the stop valve and the pressure reducer at the inlet. If the equipment is made of carbon steel, a filter should also be installed in front of the demister. It’s best to install a bypass for the strainer
