Installation issue of the ARC valve at the outlet of the lean methanol pump

Regarding the installation of the ARC valve at the outlet of the lean methanol pump, the following points should be noted: 1. Verify that the valve specifications and design parameters are compatible: Ensure that the size, pressure rating, and material of the ARC valve are suitable for the piping system at the pump outlet. 2. Installation location: The valve should be installed in a location that facilitates operation and maintenance, while ensuring that its operation is not affected by environmental factors. 3. Flow direction markings: Pay attention to the valve’s flow direction markings to ensure it is installed in the correct direction, thereby preventing damage or reduced performance caused by backflow. 4. Leak detection: After installation, a thorough leak test is conducted to ensure that there are no leaks at any of the connections. 5. Operation test: Before starting normal operation, an operation test should be conducted to check whether the valves open and close smoothly and whether they can regulate flow properly. 6. Safety measures: Given that methanol is toxic and flammable, appropriate safety measures must be taken during installation, such as using explosion-proof tools and ensuring that there are no sources of fire at the site. By following the above steps, the proper installation and safe operation of the ARC valve can be effectively ensured. If there are specific installation details or operational questions, it is recommended to consult a professional or refer to the detailed equipment installation manual. .

Well said; I’d like to add two more points: 1. Valves of this type generally require vertical installation, unless it is specified at the time of ordering that they should be installed horizontally； 2. When installing horizontally, make sure that both the main path and the bypass are in a horizontal position as much as possible. 3. Try to avoid direct diameter changes in the main path and bypass; there should also be sections of straight pipe.

The answer can be found in the comments: lol

I don’t understand. Based on the valve structure shown in the diagram, aren’t the main path and the bypass path naturally perpendicular to each other? How can it be made so that all are horizontal pipes?

Just rotate 90° around the horizontal axis of the main road, and that’s it

So the drain port at the bottom of the valve body in that diagram is also turned upward, is that right?

The drain port is on the pipeline, not on the valve

No, it’s on the valve body; it’s quite obvious.
