Help needed: selection of gate valves! Hurry up and understand!
Thread Content
A gate valve is required, with a pipeline pressure of 16 KPA; the medium is coke oven gas, and the temperature ranges from 40 to 50 degrees. Caliber 300, 80! Someone who knows the subject should help choose a model and material. I need an electric actuator. By the way, can the valve torque be calculated?
Ball valves are generally suitable for gas use, as they can handle high pressures, provide good sealing, and the required torque can be determined by our engineers
Butterfly valves seem to work as well; eccentric butterfly valves should also be suitable. Then why is a gate valve chosen for gas applications? I don’t understand what the original poster means.
The pressure is so low! First, determine what standards you need? US standard or Chinese standard? For American standards, choose 150LB ； National standard: 1.6 MPa. Connection method? Flange or welding? The material can refer to pipeline materials. What are the specific requirements for electric actuators? Explosion-proof, explosion protection rating? Switching time? With or without a handwheel?
