Railcar Unloading - Emergency Shutdown System


Versión en Español

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

UniPro Standard

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. More...

UniPro™ R (Reversible) Valve Closure System

 

UniPro RThe 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

UniPro LT

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

 

UniPro LTRThe 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...
