Top Unload Valves

Littlejohn Inc offers a range of top unload valves specifically designed for chemical tank trailers, enabling safe and efficient unloading from the tank's top-mounted inlet. These hydraulic, self-closing valves are engineered to prevent hazardous exposures by instantly shutting off flow when hydraulic pressure is lost—ideal for DOT 407/412 trailers handling corrosive or flammable liquids.

Our inventory features premium Betts stainless steel top unload valves, including both standard and internal hydraulic models. These valves are built to withstand high pressures, ensuring reliable performance under extreme conditions. The robust stainless steel construction provides excellent corrosion resistance, while their self-closing mechanisms deliver dependable shutoff and minimal maintenance.

At Littlejohn Inc, we understand the importance of efficient and secure unloading in chemical trailer operations. That’s why all our top unload valves are supported by fast shipping from six national warehouses and expert customer service to guide you toward the perfect configuration. Trust us to help you maintain both operational safety and compliance during every unloading cycle.
