KV-004
The KEJU KV-004 air lock switch is a pneumatic spare component designed for dental chair and dental unit applications. It is intended for compatible dental unit control systems where an air-operated locking or release function is required.
The KV-004 is supplied as a replacement and maintenance component rather than as a complete dental unit. Because dental air lock switches can differ in tubing connections, mounting arrangement and control application, the original component and dental unit model should be checked before replacement.
Additional pneumatic and control components can be found in our dental valve range and dental spare parts category.
KV-004 Product Snapshot
Model: KV-004
Product Type: Air Lock Switch
Control Type: Pneumatic
Application: Dental Chair / Dental Unit
Brand: KEJU
Part Category: Dental Equipment Spare Part
An air lock switch is a pneumatic control component used in applicable dental unit assemblies. In dental delivery systems, air-operated locking mechanisms can be used to release or secure movable sections of the dentist element or instrument delivery assembly during position adjustment.
When the applicable air lock control is actuated, the supported component can be repositioned according to the dental unit design. Releasing the control allows the locking system to maintain the selected working position.
Application Note
Air lock system designs vary between dental units. Before replacement, check the KV-004 against the original component, dental unit model, installation position and pneumatic connection arrangement.
The KV-004 is part of our dental valve and pneumatic spare-parts range. It is intended for dental equipment applications where a compatible air lock switch is required within the unit's pneumatic control system.
Within a dental unit, the air lock switch works as part of a larger system that may include pneumatic tubing, fittings, locking mechanisms and movable support components. Replacement should therefore be based on the complete original configuration rather than on the appearance of the switch alone.
Our dental spare-parts range includes different air-control components for different pneumatic functions. Similar product names do not necessarily mean that the switches are interchangeable.
Model | Product Type | Selection Point |
|---|---|---|
KV-001 | Single Air Switch | Check the original single-switch application and connection arrangement. |
KV-003 | General Air Switch | Select according to the required air-control function and dental unit configuration. |
KV-004 | Air Lock Switch | Check the pneumatic locking function, mounting position and tubing arrangement. |
Model numbers and visual similarity should not be used as the only basis for interchangeability. The original dental unit control function and connection arrangement should be checked before selecting a replacement switch.
For replacement projects, identifying the original function of the switch is particularly important. A component connected to similar pneumatic tubing may still perform a different control task within the dental unit.
✓ Dental unit model: provide the manufacturer and model number whenever available.
✓ Existing switch photos: provide clear images from multiple angles and show the installed position.
✓ Control function: indicate which dental unit movement or locking function the existing switch controls.
✓ Pneumatic connections: check the number, location and relevant dimensions of the tubing connections.
✓ Mounting arrangement: check how the air switch is fixed within the applicable dental unit assembly.
✓ Required quantity: specify whether the requirement is for maintenance, spare inventory or distributor supply.
The KV-004 is a pneumatic air lock switch for compatible dental chair and dental unit applications. Detailed connection, operating-pressure, dimensional and mounting specifications are available according to replacement and project requirements.

If a dental unit delivery arm or related pneumatic locking function does not release or hold as expected, the air lock switch may be one component that requires inspection. The switch should not automatically be assumed to be the source of the problem.
Pneumatic tubing, fittings, air-lock cylinders and related mechanical components can also affect locking performance. The complete pneumatic circuit and locking mechanism should therefore be inspected according to the applicable dental unit service information.
Before disconnecting pneumatic components, follow the dental unit maintenance procedure and isolate the relevant air supply where required.
If the Existing Model Number Is Unclear
Send us clear photos of the switch, tubing connections and installation position together with the dental unit model. Also describe which movable component or locking function the switch controls. This information helps our team distinguish the required air lock switch from other pneumatic dental unit components.
The KV-004 can be used for dental equipment maintenance, component replacement and spare-parts inventory where a compatible dental unit air lock switch is required.
For distributors and service providers sourcing multiple pneumatic components, send us a parts list with model references, photos and required quantities so the components can be reviewed together before quotation.

The KV-004 is a pneumatic air lock switch supplied as a spare component for compatible dental chair and dental unit applications.
In applicable dental unit designs, an air lock switch forms part of a pneumatic locking system used with a movable equipment section such as a delivery arm or instrument-table assembly. Exact operation depends on the dental unit configuration.
No interchangeability should be assumed. KV-001 is a single air switch, while KV-004 is an air lock switch for compatible dental unit applications. Check the original switch function, tubing connections and installation arrangement before selecting a replacement.
No universal compatibility should be assumed. Tubing connections, mounting configuration, pneumatic requirements and the air-lock mechanism can differ between dental unit designs. Please provide the dental unit model and original component information when requesting replacement support.
Please provide the dental unit brand and model, photos of the existing switch, tubing arrangement, installation position, controlled function and required quantity. Relevant measurements are also useful when exact compatibility needs to be checked.
Yes. Our dental spare-parts range includes multiple air switches, valves and pneumatic components. You can send us a parts list containing the required model numbers, photos and quantities for combined product review and quotation.
Request KV-004 Compatibility Support and Quotation
Provide your dental unit model, existing switch photos, tubing arrangement, installation position and required quantity. Our team can then review the KV-004 spare-part requirement, compatibility information and order details with you.
