Our UniPro™ Standard Valve Closure System is designed for 20-ton bullet tanks to 90-ton railcars. This patent-pending system prevents releases of pressurized hazardous chemicals at the source and it is designed to stand alone as a complete system or to integrate and interface with existing unloading components. The system includes the actuator, control panel, air control unit, and air supply hose. It is engineered, designed, and field-tested to ensure reliable performance while reducing installation time, maintenance, and material cost.
The actuator is constructed of aircraft-quality aluminum and high-grade carbon and stainless steel for maximum service life. The housing is sealed to prevent intrusion from dirt and water in outdoor applications, while a two-step polyurethane coating provides corrosion protection.
You may have an application requiring modified or unique hardware. In these cases, we offer an Application Evaluation Service.
Some valve closures are simply built. Ours is engineered.
Every component of the UniPro™ Valve Closure System is engineered to be more versatile, efficient, and reliable than alternative units on the market. The system includes the following:
Several valve adapters are available for use with the UniPro™ Standard Valve Closure System.
The Air Manifold Bracket clamps to the railcar dome which connects and supports the air hoses to the individual actuators.
The UniPro™ Hose Reel Assembly consists of a bottom wound spring-driven rewind hose reel with latching mechanism and 70 feet of hose. It supplies the air/nitrogen from the platform to the railcar dome. In the event of car movement, the hose follows the railcar to maintain air flow to the actuators.
The Motion Detection System is designed to mount on the loading/unloading platform near the tank car being serviced. The spool holds 25 feet of stainless steel braided cable, and the locking mechanism on the reel prevents excess cable from unwinding in the event of tank car motion. The cable can be routed around any solid object on the tank car and clipped to the pin underneath the reel. The pin is inserted through a rotating fixture above a Class 1, Div 1 switch.
The Air Control Unit supplies the proper amount of clean pressurized air/nitrogen to the system. The equipment is pre-assembled for simple installation. It is available for non-explosive and explosive environments.
The Air Receiver Assembly allows the UniPro™ System to function even if power or air pressure is lost. The unit is designed to accommodate up to two railcars per assembly. Typically, it is mounted out of the way under a rack and attaches to the Air Control Unit.
The Control Panel automatically activates the actuator in an emergency. The system is manually activate by depressing the emergency stop button on the panel. The panels are listed by Underwriters Laboratory to UL 508A for Enclosed Industrial Control Panels and the equivalent cUL mark in Canada. In applications where CSA listed control panels are required, please contact us. We also can supply custom panels for explosive environments.
The Remote Emergency Stop Pushbutton Panel (E-Stop Panel) may be installed wherever convenient for operators to reach in an emergency. The operators can use the E-Stop Panel to remotely shut the railcar valves without approaching the railcar. It is available for non-explosive and explosive environments.
Our UniPro™ Standard Valve Closure System is supported by our experienced technicians who can provide operator training, product inspection, recertification of actuator torque, or perform scheduled preventive maintenance. Additional charges may apply for these services.
