ABER – Y Pass with Relief Valve (P)
Experience unparalleled pressure stability and safeguard your high-capacity hydraulic circuits with the ABER Y-Pass Bypass with Relief Valve. Available at Thm Hydraulics, this highly specialized valve is specifically engineered to integrate flawlessly with heavy-duty pumps ranging from 110cc to 135cc. Built to handle punishing industrial environments, the BPR110H model sustains continuous operating pressures up to 350 bar (rated up to 400 bar peaks) and is actuated by a responsive 24V DC solenoid (with 12V DC options available). By allowing a continuous, calculated fluid bleed-off when disengaged, this bypass valve prevents catastrophic system overheating during continuous vehicle operation, making it a mandatory protective component for demanding mobile hydraulic networks.
Core Technical Specifications:-
- Component Architecture: Y-Pass Bypass Valve with Integrated Relief
- Model Series: ABER BPR110H Series
- Pump Compatibility: Engineered for pumps from 110cc to 135cc
- Maximum Operating Pressure: 350 Bar (Peak rating up to 400 Bar)
- Solenoid Voltage: 24V DC standard (12V DC variant also available)
Critical Installation & Operational Directives:-
To ensure safe operation and prevent catastrophic system rupture from overheating, the following rigorous installation and operating procedures must be followed:
- Transit Protocol: Every time the vehicle is in motion, the solenoid must be explicitly switched OFF to allow the bypass to function correctly.
- Mandatory Cooling Bleed: When the solenoid valve is OFF, a minimum of 12% of the theoretical pump flow must exit the drain line directly to the tank. This continuous circulation is critical to prevent the hydraulic system from overheating while the vehicle is working.
- Strict Drain Line Routing: The drain line must be installed directly from the bypass valve to the oil tank and terminate below the reservoir's oil level. If the installation prevents the drain line from being submerged, a spring-loaded check valve must be installed on the line.
- Calibration Responsibility: ABER and Thm Hydraulics are not liable for the final adjustment and sealing of the relief valve pressure. Precise calibration to your system's requirements is strictly the responsibility of the installing technician/customer.
Key Features & Engineering Advantages:-
- Active Thermal Management: The engineered 12% flow bypass entirely mitigates the extreme heat generated by heavy-duty 110cc+ pumps running continuously during vehicle transit, extending the life of your fluid and seals.
- Electrical Command Integration: The 24V (or 12V) solenoid allows operators to easily engage or disengage the bypass function directly from the cabin controls, ensuring the system is only fully pressurized when actual work is being performed.
- Heavy-Duty Pressure Containment: Designed to safely manage the brutal 350 to 400 bar forces generated by large displacement pumps without suffering from internal blowouts or structural fatigue.
- Streamlined Circuitry: Combines a high-pressure bypass and a customizable relief valve into a single unit, saving critical chassis space and reducing the number of vulnerable plumbing connections.
Ideal Industry Applications:-
The strict thermal management and high-pressure capabilities of the ABER BPR110H make it essential for:
- Heavy Refuse & Waste Collection: Protecting the continuous-running hydraulic pumps on large garbage trucks and roll-off carriers as they drive between stops.
- Municipal Winter Fleets: Preventing fluid overheating on heavy snowplows and salt spreaders that require the pump to run continuously while the truck is driving.
- Heavy Commercial Trucking: Serving as the thermal management hub for large articulated dump trucks and specialized multi-trailer tippers.
- Mobile Construction Equipment: Regulating massive 110cc+ PTO-driven pumps on heavy concrete mixers and mobile crane carriers during highway transit.
Why Choose the ABER Y-Pass Bypass Valve?
- Eradicate Overheating: The calculated continuous bleed entirely solves the problem of fluid burning up while your heavy trucks are driving down the highway.
- Sustain 350-Bar Power: Specifically built to handle the massive displacement and brutal pressures of the industry's largest 110cc to 135cc PTO pumps.
- Customizable Safety: The integrated relief valve gives your maintenance team the power to perfectly dial in the exact pressure threshold your specific machinery requires.
