The GL34-B-S is a cabin-mounted Dual-Button Manual Pneumatic Control Valve with Integrated Indicator Light interfaces. Universally deployed in the dashboard or console consoles of dump trucks, heavy tippers, and semi-trailers, this multi-circuit valve allows drivers to manage two independent pneumatic lines safely from a single, space-saving panel module.
Dual-Button Independence: Houses two completely isolated manual pneumatic circuits inside one compact square enclosure. Drivers can control two separate auxiliary systems without cluttering the cabin with multiple switches.
Dual-Channel Indicator Circuits: Each button features its own dedicated internal electrical contact switch. When a line is activated (e.g., PTO engaged or tailgate unlocked), the circuit closes to illuminate a warning light on the console or vehicle dashboard.
Critical Road Safety Protection: The prominent feedback lights act as essential visual reminders. They prevent catastrophic mistakes, such as highway driving while the PTO is spinning or traveling with an unlatched tailgate.
Heavy-Duty Oil-Resistant Seals: Internal spools are fitted with premium Viton or NBR O-rings, which maintain airtight integrity against moisture, chassis vibrations, and the micro-particles of oil common in truck air systems.
Applications
Vehicles: Heavy dump trucks, semi-trailers, side tippers, refuse vehicles, and tanker trucks.
Systems: The classic PTO engagement + Air tailgate lock combination, dual-direction hydraulic routing, side-dump directional switching, and chassis sliding-axle locks.
GL34-B-S-Dual-button-manual-valves are typically packaged securely to prevent damage during transit. The packaging includes:
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.
Button 1 (Left): Activates the Power Take-Off (PTO) gear on the transmission.
Button 2 (Right): Activates the Pneumatic Tailgate Locking Safety Cylinder.
In specialized setups, it can also be used to toggle side-dump selector valves, sub-frame sliding locks, or pneumatic dust tarps.
Moisture Freezing: If the truck's auxiliary air dryer cartridge is old or saturated, moisture enters the GL34-B-S valve. In winter, this water freezes into micro-ice crystals that physically jam the internal spool.
Oil Sludge: If the vehicle's air compressor is blowing a small amount of oil, the oil blends with the valve’s factory grease, turning into a thick, sticky sludge that creates mechanical drag. Replacing the air dryer and flushing the lines usually resolves this.
The Test: Disconnect the delivery lines running from the back of the GL34-B-S to the chassis components (like the PTO actuator cylinder).
Analysis: If air still blows out of the valve's exhaust port, the internal O-rings of the GL34-B-S are shot, and the valve must be replaced. If air starts blowing out of the disconnected air hose back toward the cabin, the cylinder seal under the truck (e.g., on the PTO) is blown, causing air to back-feed into the cabin valve.
