UniPro™ QT Pneumatic Valve Closure System

Our UniPro™ QT Valve Closure System is designed for 20-ton bullet tanks to 90-ton railcars.  It prevents releases of pressurized hazardous chemicals at the source. It is designed to stand alone as a complete system or to integrate and interface with existing unloading components. The system includes the actuator, air supply hose, air control unit, and control panel. 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.

Some valve closure systems are simply built. Ours is engineered.

Features

  • For a variety of ball-type angle valves
  • Requires 90 psig at -40°F to operate
  • Closes valves with 30 lb-ft of torque in less than 5 seconds
  • For use on containers of hydrogen chloride, vinyl chloride, monomer methyl mercaptan and other pressurized hazardous gases.
  • Just 3.5 pounds
  • Designed in accordance with The Chlorine Institute’s guidelines

System Components

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:

Valve Adapters

Several valve adapters are available for use with the UniPro™ QT Valve Closure System.

Hose Reel Assembly

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.

Motion Detection System

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.

Air Control Unit

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.

Air Receiver Assembly

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.

Control Panel

The Control Panel automatically activates the actuator in an emergency. The system is manually activated 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.

Remote Emergency Stop Pushbutton Panel

The Remote Emergency Stop Pushbutton Panel (E-Stop Panel) is 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.
