Frequently Asked Questions About the UniPro™ Valve Closure Systems

Why is the UniPro™ Control Panel bigger than the panel for the other system used on tank car valves?

Answer:

UniPro Control Panel

UniPro Custom Control Panel

The UniPro™ Control Panel is a true NEMA 4X enclosure that is listed by Underwriters Labs. We chose not to use space-saving electronics specific to the UniPro™. Instead, the UniPro™ Control Panel uses familiar components that are readily available at any electrical supply. This prevents waiting for special-order electrical parts should the need arise while at the same time protects the contents from the weather in a true NEMA 4X enclosure.
