Since 2003 the NVRG Valve Clatter has been a full color monthly publication varying in size from 12 to 20+ pages. The majority of our members receive it in PDF format via email. Members who do not use email receive a printed B&W via snail mail. Our Valve Clatter has been published monthly, with few exceptions, since March 1978 when it came to life as a single page, two-sided flyer. In the archives below you’ll find PDF copies of recent Valve Clatter’s published in 2020 and after. Click here for Valve Clatter’s published prior to 2020. If you chose to republish any part of our Valve Clatter please credit the Northern Virginia Regional Group and our Valve Clatter. Enjoy!
