Industrial vacuum inlet valves provide convenient connection points for vacuum hoses throughout central vacuum cleaning systems. Installed at designated locations along the vacuum piping network, these valves allow operators to connect cleaning hoses and accessories without requiring a separate vacuum producer at each pickup point.
Our industrial vacuum inlet valves feature spring-loaded, self-closing covers and are available in several hose sizes and threaded connection configurations. They are commonly installed in manufacturing plants, warehouses, woodworking facilities, and other industrial environments requiring centralized vacuum cleaning and material pickup.
Industrial vacuum inlet valves provide hose connection points throughout central vacuum piping networks. Operators can connect vacuum hoses at designated locations to clean equipment, floors, and work areas without transporting portable vacuum units throughout the facility.
Manufacturing plants use industrial vacuum inlet valves to provide convenient cleaning access near production machinery, processing equipment, and workstations. Strategically positioned inlets help support routine housekeeping, collection of compatible dry materials, and equipment maintenance.
Vacuum inlet valves can provide localized hose access for cleaning dust, chips, and debris from machinery and surrounding work areas. They are useful in woodworking, fabrication, and industrial processing facilities where a compatible central vacuum system is used for housekeeping and material pickup.
Industrial vacuum inlet valves are used in compatible material recovery and cleanup systems to provide access points along vacuum tubing networks. Proper hose selection, inlet sizing, and system capacity help accommodate the type and quantity of material being collected.
Industrial vacuum inlet valves are available in different sizes and constructions to accommodate specific central vacuum system requirements. Selecting the proper valve depends on hose diameter, threaded connection size, material, and vacuum operating conditions.
The published dimensional table includes standard hose sizes from 1-1/2" through 4", along with a 1.8" Spencer hose configuration. Larger inlet valve sizes may also be available; contact us to confirm the appropriate part number and connection requirements.
When selecting an industrial vacuum inlet valve, confirm the vacuum hose size, MNPT connection diameter, piping configuration, and system vacuum requirements. Proper sizing helps ensure compatibility between the inlet valve, vacuum hose, connecting fittings, and central vacuum piping network.
Consider where the valve will be installed and how frequently it will be used. Inlet valves should be positioned at accessible locations that allow hoses to reach the intended cleaning areas. The vacuum system should also provide sufficient airflow and suction for the connected cleaning tools and expected material loading.

An industrial vacuum inlet valve provides a connection point for vacuum hoses in a central industrial vacuum cleaning system. Installed along the main vacuum piping network, these valves allow operators to connect hoses at convenient locations throughout a facility. Spring-loaded, self-closing covers help close unused inlet connections when hoses are disconnected.
1-1/2-inch and 2-inch inlet valves feature aluminum construction with spring-loaded, self-closing covers. 2-1/2-inch through 6-inch inlet valves feature Schedule 40 bodies with machined interiors and 11-gauge painted steel spring-loaded plates. Larger valves include a palm plate to assist opening under high vacuum conditions.
Our published inlet valve table includes 1-1/2-inch, 1.8-inch Spencer, 2-inch, 2-1/2-inch, 3-inch, and 4-inch hose sizes. Larger 5-inch and 6-inch inlet valves are also described in our product information; contact us to confirm their availability and part numbers. Refer to the specification table for the corresponding MNPT connection sizes.
MNPT stands for Male National Pipe Thread. It identifies the male threaded connection used to install the inlet valve into a compatible threaded fitting or piping connection. The MNPT size may differ from the nominal vacuum hose size. For example, part number VC-150 accommodates a 1-1/2-inch hose and has a 2-inch MNPT connection.
The VC-180 inlet valve is listed for a 1.8-inch Spencer vacuum hose and has a 2-inch MNPT connection. This is a specialized hose-size designation. Confirm the hose-end fitting and connection dimensions before ordering rather than assuming compatibility with standard 1-3/4-inch or 2-inch hose assemblies.
Industrial vacuum inlet valves use a spring-loaded, self-closing cover that can be opened to connect a compatible vacuum hose. When the hose is removed, the cover closes over the inlet to help reduce unwanted air entering the central vacuum piping system. Larger valve models feature a palm plate to assist opening under high vacuum conditions.
Select an inlet valve based on the vacuum hose size, MNPT connection size, hose-end compatibility, piping configuration, and operating vacuum requirements. Also consider the intended installation location and how the inlet will be used. Refer to the inlet valve specification table for listed part numbers and sizes, or Contact Us for assistance choosing a compatible valve.
Not sure which industrial vacuum inlet valve is right for your central vacuum cleaning system? Provide the vacuum hose size, MNPT threaded connection size, piping configuration, and operating vacuum requirements, and our team can help identify the appropriate inlet valve. We can also assist with specialized hose connections, including 1.8-inch Spencer vacuum hoses, and help confirm availability of larger inlet valves and compatible fittings for your installation.
