We don't show 637175 as crossing over to our 640908 valve. The 640908 replaced the 637140, 618253, 637580 and 633325, so I can't confirm it replaces yours.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
