Figure 935 Air & Vacuum Valves are typically installed at system high points where air and sewage gas naturally rise during filling and vacuum first forms during draining. The elongated body is designed to maintain an air gap between the solids bearing fluid and the valve’s internal mechanism to minimize fouling and spillage.
Figure 935F includes optional ‘back flushing attachments’ to facilitate cleaning sludge and debris from the valve.
