Wryxia PTO Control Valve Set With Kickout

The Wryxia set installs in the driver’s cab to manage lifting, intermediate stop, and lowering of the oil cylinder, with a controlled lowering (feathering) feature that prevents rapid descent. The kit includes a dual valve air kit with a kickout function for safer unloading operations. The included wiring and fittings support a straightforward installation, and the setup uses an OD 6mm air pipe compatible with typical semi-truck pneumatic lines. It operates across wide temperature ranges and includes corrosion-protected components for durable field use.
Key features include multiple working positions: lifting, intermediate stop, descending, and PTO. When the vehicle body lowers, the PTO disengages automatically, and warning lights provide operator feedback. This kit is designed for trucks that require precise and smooth load control, particularly in dump applications where feathering reduces shock loads. The valve arrangement and construction emphasize reliability in harsh environments.
Wryxia PTO Control Switch Set With Kickout

This kit uses a valve with a four-position PTO switch that includes lifting, intermediate stop, descending, and PTO modes. The kickout feature aids in safely disengaging the PTO during unloading cycles, and a spray-coated console tower delivers good anti-corrosion protection. The kit’s air pipe dimension (OD 6mm) and operating range (50-145 PSI, -25 to 80 °C) align with many standard dump pump systems. An integrated warning system helps keep operators aware of active PTO engagement.
Reference to performance highlights: feathering-controlled descent to avoid abrupt drops, solid construction for heavy-duty use, and a straightforward control sequence for daily truck operations. The console tower’s finish adds longevity when exposed to road grime and weather conditions. Overall, this option emphasizes safe, user-friendly control with reliable disengagement when the dump bed moves.
Wryxia Full PTO Valve Kit With Console Tower And Air Tube

This extended kit adds a console tower along with a 10-meter air hose, offering a complete control surface and flexible reach for operators. The four-position control mirrors other Wryxia setups: lifting, intermediate stop, descent, and PTO engagement. Feathering remains a primary feature to prevent jerky movements during lowering. The assembly emphasizes corrosion resistance through coated components, ensuring operation even in humid or salty environments often encountered on long-haul routes.
Operators benefit from a cohesive kit that reduces installation time and ensures consistent performance across multiple dump and hydraulic applications. The inclusion of a long air line supports installations where the valve sits away from the cab or behind the cab in a dash area, enabling ergonomic operation without compromising control fidelity.
Kozlira PTO Hoist Control Valve Air Kit With Kickout

The Kozlira kit provides a complete air control solution with a kickout feature, designed for dump truck tipper systems. It replaces various component models and integrates a four-gear PTO switch and auto-disengagement to automatically disengage when the bed lowers. A high-contrast, safety-oriented light improves operator visibility during operation, contributing to safer unloading sequences. Feathering control is highlighted to ensure smooth load transfer and minimize mechanical shock during descent.
Construction emphasizes durability in rugged environments, with a focus on precise, smooth operation. This kit is particularly suitable for fleets requiring reliable automatic disengagement and a straightforward control layout that supports efficient dump operations and reduced cycle times.
National Drivetrain PTO Tower Kit With Kickout

This National Drivetrain kit features an 8″ tall PTO control tower with a kickout function, designed to deliver robust, reliable control for PTO and pump systems. The 8-inch height provides a balanced reach for cab installation while maintaining clear visibility of status indicators. The kit emphasizes durable construction and straightforward operation, supporting precise control for dumping and hydraulic unloading tasks. The included kickout mechanism ensures safe disengagement during load changes, reducing chances of accidental PTO engagement during transit or loading.
Users can expect a cohesive control experience that combines ease of installation with dependable performance. The tower design helps centralize control in a convenient location, supporting consistent operation across various truck models and body configurations. This option is well-suited for fleets prioritizing a proven, factory-style control tower solution with kickout safety features.
Buying Guide: Key Purchase Considerations
- Control fidelity: Look for feathering-capable valves and self-locking middle positions to prevent unintended movements during dumping.
- PTO disengagement: Automatic disengagement when the body lowers improves safety and reduces operator workload.
- Durability: Coated surfaces, corrosion resistance, and rugged fittings extend service life in harsh environments.
- Installation scope: Kits with consoles, towers, and long air lines simplify installation in diverse truck layouts.
- Compatibility: Ensure air line size (commonly OD 6mm) and pressure range (often 50-145 PSI) align with your pump and compressor specs.
- Safety features: Integrated warning lights and clearly marked control positions help operators avoid mistakes during unloading.
- Replacement parts: Availability of replacement valves, switches, and air hoses reduces downtime if components wear out.
Performance Perspectives
- Safety-first: Kits with automatic disengagement and warning indicators reduce the risk of accidental PTO engagement during operation and transit.
- Operational efficiency: Feathering and precise control translate into smoother dump cycles and faster, more predictable unloading.
- Maintenance considerations: Anti-corrosion finishes and robust connectors minimize maintenance needs in humid or salty environments.
- Installation practicality: All-in-one kits with consoles and towers save time and provide a neater installation in factory or field settings.
