Central Vacuum Inlet Valve

Made of durable steel, this inlet valve has 2" MNPT thread to screw it into a 2" inlet port. It is paired with a VCHA150 Adapter to create a smaller inlet port that accepts 1.5" vacuum hose. This is commonly used with central vacuum systems. The valve has a built-in spring-loaded cap with a rubber gasket that shuts off the air flow when closed.

Common Issues

These valves are durable and long-lasting, but like any heavily used part you may eventually encounter problems with them. They're relatively simple mechanisms, so these issues are pretty straightforward and easy to diagnose. In most cases, the most sensible solution is to replace your inlet valve if you deal with any of the following difficulties:

• Valve Cap Not Working Correctly: If your valve cap is loose, misaligned, or stuck open/shut, chances are the spring mechanism is damaged.
• Cap Not Sealing: If the spring mechanism is working and the cap is closing but you still feel suction, the gasket is probably the culprit. Over time, gaskets can wear, crack, or fall off.
• Valve Not Threading: If you aren't able to twist the valve securely into your 2" port, it's possible the threads are damaged. This may happen if the valve is dropped, hit with something heavy, or extremely overtightened. Of course, you'll want to check that the port itself is not impaired if there's no visible damage to the inlet valve.

Explaining Inlet Valves in Different Central Vacuum System Applications

It's important to understand that this inlet valve does not work the same as inlet valves or wall plates used with central vacuum systems inside homes, offices, and other buildings. Although they serve a similar function of being a spot to create a hose connection, there is one key difference: electricity. Inlet and valves and wall plates inside a building have an electrical connection to the central vacuum system. The hoses that are connected to them have a metal band on them. When the hose is inserted, it sends a low-voltage signal telling the central vacuum system to activate. Car wash central vacs, on the other hand, are either always running, operated with a push button, or triggered by a payment system. Consequently, the inlet valves in these applications only serve the basic functionality of being a spot to hook up hose.
