The Cla-Val Pacific Model CRD18 Pressure Reducing Control automatically reduces a higher inlet pressure to a lower outlet pressure. It is a direct acting, spring loaded, diaphragm type control regulator that operates hydraulically or pneumatically. This valve is held open by the force of the compression spring above the diaphragm, and closes when the downstream pressure acting on the underside of the diaphragm exceeds the spring setting. The CRD18 senses downstream pressure directly.
