Dixon Valve and Coupling Co. of Chestertown, Md., recently introduced an “Overfill Prevention System’’. That protects tank trucks against the risk of overfilling when transferring liquids.

Founded in 1916, Dixon is an international manufacturer and supplier of hose fittings, fluid control products and accessories. The company serves various industries, including the agricultural, chemical, construction, fire prevention and suppression sectors. Also the food and beverage, industrial, mining, petrochemical and pharmaceutical segments.

“…Particularly well-suited for applications involving bulk liquid transfer such as chemicals, as well as for locomotive, marine, off-road and stationary power fueling,’’Dixon’s overfill system “is particularly well-suited for applications involving bulk liquid transfer such as chemicals, as well as for locomotive, marine, off-road and stationary power fueling,’’ the company said in a press release.

The system utilizes dry disconnect fittings that prevent leaks and are more secure, making it more spill-resistant compared to currently-offered system designs, the company said. The system relies on level sensing in the tank to control the flow of the liquid.

Dixon’s system is engineered with a single point of connection for both the fluid flow and the electrical connection. Visual confirmation of system integrity at the point of fluid connection allows for immediate user feedback in the case of any system faults.

Dixon Valve Overfill Protection Functional Design

“Important design features include a three-inch, dry-disconnect coupler and adaptor that eliminates spillage when connecting and disconnecting during fluid transfers. A single-point, push-and-turn connection is supported by LED controls that signal the system status to users,’’ the press release says.

The controller automatically shuts off the pump or closes the valve when the tank is full.

“This fail-safe feature prevents any fluid flow once the tank is full, and also protects against fluid flow if there is any fault detected in the system. It is an improvement over vacuum-operated systems, which can experience incidences of liquid flow shutting off too soon or not at all,’’ the company said.

The dry-disconnect coupler and adapter are made of aluminum, 316 stainless steel and brass-gunmetal materials. The coupler and adapter rings are made of chlorinated polyvinyl chloride (CPVC) material.

Specs: Working pressures for Dixon’s Overfill Prevention System (at 70˚F) are as follows:  Aluminum (230 psi); Stainless Steel (360 psi); Brass/Gunmetal (230 psi). The system can be integrated with float switches and ADS probes, the Dixon industrial fluid control shutdown and alarm system for overfill protection.  It can be provided as intrinsically safe for hazardous environments.

“Our overfill prevention system is a reliable and fail-safe solution – one that’s easier to install and operate and allows for easy troubleshooting,’’ said Sean Anderson, Dixon Valve’s product manager.
