Abstract
A fastener-less valve cover plate assembly that can be used to enclose a pressure chamber, such as a valve chamber of a relay valve. Installation of the components of the fastener-less valve cover plate assembly is simplified as compared to prior art cover plates utilizing fasteners, while still providing suitable performance. In addition, the fastener-less valve cover plate assembly is not readily disassembled with common tools thereby discouraging tampering.
