The waste tank vacuum regulating system can be controlled by a Kunkle Valve which limits relief to 14” of mercury and prevents vacuum and airflow loss, which is common on traditional spring-loaded relief valves.
This vacuum regulating system provides outstanding water extraction capabilities.If you have a smaller blower like a 36 or 45 this kunkle valve will increase your vacuum equivalent to the larger 47 or 50 blower.
·This 2” NPT Kunkle Valve is set at 13”-14” HG (the mount plate is not included, purchased separately)
·This Kunkle valve can be adjusted to 2-inch HG to 29-inch HG with a temperature rating of-20° to 400°F
