MS-AIR-TF/LF/AIR-43
Cissoko
The BKGL34L-C is a robust cab-mounted manual air control valve engineered for the demanding environment of tipper trucks. This precision bidirectional control valve seamlessly integrates the three essential functions of tipping, stopping, and dropping into a single, ergonomic unit. With a pneumatic control range of 0.8 MPa and a 4mm nominal diameter, it delivers accurate and reliable performance for your dump truck hydraulic system. Featuring a durable metal operating lever and intuitive side buttons, it allows for effortless control directly from the driver's cab. Its construction from high-grade engineering plastics ensures longevity, making the BKQF34L-C the ideal tipper truck control valve for construction, mining, and heavy-duty transport applications, guaranteeing smooth and safe operation.
Three-in-one minimalist control (one handle does it all) : A single handle perfectly integrates the three working modes of "lifting-stopping-falling" . When switching to the stop position, the air circuit locks instantly, which can keep the cargo box weighing tens of tons stable at any height in the air and prevent accidental slippage.
Automatic PTO pneumatic control linkage (hardcore error prevention) : The integrated PTO pneumatic switch can only be turned on for lifting; when the handle is pushed back to the initial position, the system will automatically release and forcibly shut down the PTO , completely eliminating the risk of the driver burning out the transmission due to forgetting to disengage the PTO while driving at high speed.
Proportional slow descent buffer technology (safe crush protection) : The descent gear travel uses a micro-adjustable slide valve structure, with air pressure output proportional to the handle angle. The driver can finely adjust the cargo box descent speed to achieve a smooth descent from slow to fast , avoiding heavy falls and providing robust protection for the chassis beams.
Heavy-duty, airtight material (robust and leak-proof) : withstands pressure up to 1.2 MPa , perfectly matching heavy-duty truck air brake systems. Made with a combination of heavy-duty engineering plastics and aluminum alloy, it is waterproof, dustproof, and resistant to severe vibrations, perfectly adaptable to harsh all-weather environments such as mines and construction sites.

Applications
Heavy Wheel Loaders & Excavators: Used to split fluid from the main piston pump, prioritizing smooth hydraulic power steering lines while routing the remaining flow to drive heavy boom, arm, and bucket actions.
Complex Sanitation & Garbage Compactors: Coordinates multiple automated steps. It precisely distributes pump power so the vehicle can lift heavy trash containers smoothly while running high-pressure compaction blades at a controlled, uniform speed.
Large Mobile Mining & Drilling Rigs: Feeds high-pressure oil to auxiliary stabilizer jacks while maintaining steady, non-pulsating rotation fluid on the primary drill motor line.

Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Answer : This is standard automotive pneumatic component port naming; be extremely careful not to connect it incorrectly (it typically matches a Ø6mm air hose).
1. Inlet (or IN) : Air inlet, connected to a regulated air source from the heavy truck's air tank (air brake system).
21 Port (or OUT 1/Tipping) : Lift control port. Air is released from this port when the handle is turned to "Lift". It is connected to the lift control end of the main distribution valve of the oil pan.
22 Port (or OUT 2/Lowering) : Lowering control port. Air is released from this port when the handle is turned to "Lower". It is connected to the lowering control end of the main distribution valve.
3 Port (or EXH) : Exhaust port/muffler port, used to expel residual high-pressure air when shifting gears.
PTO port : Connects separately to the control terminal of the power take-off valve of the gearbox.
Answer : Please follow these steps to troubleshoot gas path and operational issues:
The proportional slow-descent handle is not fully pushed : This valve has a proportional fine-tuning function. If the handle is only pushed open slightly, the output air pressure is weak, and the hydraulic main valve core under the chassis cannot fully open, resulting in extremely slow oil return. Please try pushing the handle all the way down.
22-port (descending port) air hose bends or leaks : Check whether the 22-port air hose from the cab to the distribution valve under the vehicle has been deformed or bent due to vehicle bumps, resulting in poor airflow, or whether there is a serious leak at the joint.
Main hydraulic distribution valve stuck : If the air valve outputs normal air pressure (strong airflow is ejected when the air pipe is removed), it means that the control valve is not the problem. The problem lies in the hydraulic distribution valve under the chassis, where the main valve core is stuck due to the oil being too dirty.
Answer : This situation is a typical case of "gas arriving but electricity not arriving" or "gas line not fully pressurized . "
First, check if the air source pressure (port 1) has reached 0.6 - 0.8 MPa or higher . The air brake system of heavy trucks has an air pressure protection valve. If the overall air pressure of the vehicle is too low (such as when starting without fully inflating), the system will automatically cut off the auxiliary air circuit, causing the control valve to be unable to output sufficient control air pressure.
Secondly, confirm that the power take-off gears in the transmission are truly engaged. Sometimes, even if the switch is pressed, the power take-off may not actually operate because the mechanical gear teeth or the clutch is not fully depressed. Consequently, the hydraulic pump will not work, and lifting will not be possible.
answer :
Continuous air leakage in the "stop" or initial position : This is usually due to severe wear, aging, or damage to the pneumatic slide valve seals (O-Rings) inside the control valve by moisture/metal filings in the air path , causing cross-contamination between the high-pressure air chamber and the exhaust chamber.
Air backflow from under the chassis : If the air leak is extremely violent, another possibility is that the hydraulic main distribution valve cylinder oil seal under the chassis is damaged, and the high-pressure gas from the chassis is flowing back into the control valve in the cab along the air pipe.
Repair method : Disassemble the control valve (the vehicle air pressure must be released first), replace the precision fluororubber seal at the valve core and apply special pneumatic guide grease; if the air passage inside the valve body is severely scratched by sand particles, the control valve assembly needs to be replaced.
Answer : This is the most common "gas path freezing" fault encountered in winter in northern and high-altitude mines .
Because the air compressed by the truck's air compressor contains water vapor, if the vehicle's dryer filter (dryer canister) is not replaced for a long time , a large amount of moisture will enter the control valve inside the cab with the airflow. At temperatures below -10 degrees Celsius, the residual moisture will freeze in the micron-sized gaps between the valve cores, sealing them completely.
Solutions and Prevention : Never use an open flame to directly heat the plastic valve body! You can thaw it by applying a warm towel to the valve body casing. The permanent solution is to immediately replace the entire vehicle's air dryer filter and install specialized antifreeze brake fluid in the air system.
