Components of the UniPro™ Valve Closure System
UniPro™ technology is designed to stand alone as a complete emergency shutdown
system, or to integrate and interface with existing unloading components that may
already be in place at the site. The basic system incorporates several components.
Each component has been engineered, designed, and pre-assembled by Powell to ensure
proper system performance and reduced installation time, labor and material cost.
UniPro™ systems can accommodate ball-type or plug-type valve handles found
on any one of several pressurized containers of hazardous gases. Other system components
include a wide-range of valve adapters, a hose reel, air control system, air receiver
assembly, railcar motion detection system, and a basic control panel to activate
the system.
Powell can also supply custom control panels to control new or automatically existing
chlorine and pad gas valves and chlorine detectors. An emergency stop (E-Stop) panel
can also be installed where ever convenient for an operator to remotely shut the
railcar valves from a safe distance.
UniPro™ Pneumatic Actuators
UniPro™ Standard Valve Closure System
Designed to close a variety of plug-type angle valves on railcars and tank trucks
with dome sizes between 24 and 42 inches in diameter. Automatically responds to
any alarm input, closing valves with 120 lb-ft of torque in less than 10 seconds.

UniPro™ R (Reversible) Valve Closure System
The only reversible emergency valve closure technology designed for 20-ton bullet
tanks to 90-ton railcars, this patent-pending system prevents reportable releases
of pressurized hazardous gases at the source. Plus, the UniPro™
R system is easily "reversible" - helping reduce operator effort and potential
injuries. More...
UniPro™ LT (Low Torque) Valve Closure System
The only low-torque emergency valve closure technology designed for 20-ton bullet
tanks to 90-ton railcars, this patent-pending system prevents reportable releases
of pressurized hazardous gases at the source. Plus, the UniPro™
LT system is specifically designed for "low-torque" valves to prevent
damage to the valve seat. More...
UniPro™ LTR (Low Torque Reversible) Valve Closure System
The only reversible, low-torque emergency valve closure technology designed for
20-ton bullet tanks to 90-ton railcars, this patent-pending system prevents reportable
releases of pressurized hazardous gases at the source. Plus,
the UniPro™ LT system is specifically designed for "low-torque" valves to prevent
damage to the valve seat. More...
UniPro™ QT (Quarter Turn) Valve Closure System
The only quarter-turn emergency valve closure technology designed for 20-ton bullet
tanks to 90-ton railcars, this patent-pending system prevents reportable releases
of pressurized hazardous gases at the source. Plus, the UniPro™ QT system
is uniquely designed for "quarter-turn" ball-type valves.
