Bendix offers a wide range of pneumatic modulation valves (PMVs), specifically designed for the trailer industry. These valves play a critical role in ensuring safe and efficient braking and suspension systems in trailers. This guide provides an overview of various Bendix Pmvs and their functions.
Bendix Trailer Spring Brake Valves: Ensuring Safety and Performance
Bendix spring brake valves are crucial for pressure protection and preventing damage to wheel-ends. Two prominent models are the SR-5™ and SRC-7000™.
SR-5™: Rapid Release for Quick Starts
The SR-5™ trailer spring brake valve facilitates the rapid release of spring brakes, enabling quicker vehicle starts thanks to its integrated reservoir relay function. This efficiency minimizes downtime and improves overall productivity.
SRC-7000™: Durability and Ease of Installation
The SRC-7000™ boasts a lightweight, compact, and corrosion-resistant design. Its swivel-mount design and large internal ports simplify installation and minimize contamination. Notably, the SRC-7000™ is a key component of the Bendix® TRSP® (Trailer Roll Stability Program), enhancing safety and stability.
Other Essential Bendix PMVs for Trailer Applications
Beyond spring brake valves, Bendix offers a variety of other PMVs for diverse trailer functionalities.
SR-2™: Prioritizing Service Brakes
The SR-2™ trailer spring brake valve prioritizes service brake function. It simultaneously fills spring brake chambers and the reservoir, ensuring sufficient service brake pressure upon spring brake release.
R-12P™: Boosting Control Signals
The R-12P™ relay valve, characterized by zero hysteresis and zero crack pressure, accelerates the control signal from the tractor to the trailer’s service relay valves. It also functions as a slave to the Antilock Braking System (ABS), extending antilock capabilities to remote axles.
PR-3™: Protecting Air Suspension Systems
The PR-3™ pressure protection valve commonly supplies air to trailer suspension systems. Available in various pressure settings, it can also power other accessories as needed. This versatility makes it a valuable asset in trailer configurations.
PP-1®: Maneuvering Control for Dollies
The PP-1® push-pull valve aids in dolly maneuvering. When a dolly is pneumatically parked, pushing the PP-1® releases the service application, allowing movement. Pulling the button re-engages the parking system.
TLV-9000™: Precise Lift Axle Control
The TLV-9000™ trailer lift axle valve seamlessly integrates with Bendix® TABS-6™ Advanced controllers. Its automated control optimizes payload distribution by precisely controlling the raising and lowering of the axle. It also prevents service brake application to a lifted axle when used with the Bendix® TR-3™ lift axle service shut-off valve.
TR-3™: Versatile Inversion Valve for Dollies and Trailers
The TR-3™ inversion valve serves distinct purposes in dolly and trailer applications. For dollies, it enables pneumatic parking. In trailers, it prevents wheel lock-up on lifted axles.
SV-4™: Synchronization for Converter Dollies
The SV-4™ synchronizing valve, used on converter dollies, manages air delivery to the rear trailer, prevents emergency brake application in specific scenarios, and assists in park timing.
Conclusion: Bendix PMVs – Reliability and Performance for the Trailer Industry
Bendix PMVs are essential for the safe and efficient operation of trailers. From spring brake control to lift axle management, these valves provide reliable performance and contribute to overall system integrity. Bendix’s commitment to innovation and quality ensures that their PMVs meet the demanding requirements of the trailer industry.
