UniPro™ QT (Quarter Turn)
Pneumatic Emergency Valve Closure System
Avoid production slow downs, operator injury, or lengthy and expensive environmental
cleanups by stopping dangerous chemical leaks with the UniPro™ QT Pneumatic
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
accidental releases of pressurized hazardous gases at the source. Plus, the UniPro™
QT system is uniquely designed for "quarter-turn" ball-type valves. Improve
your Risk Management Planning (RMP) scenarios with a pneumatic-powered system that
not only promises easy installation and low maintenance, but also superior performance
UniPro™ System Components
FOR BALL-TYPE VALVES
Designed to close a variety of ball-type angle valves on railcars and tank trucks
with dome sizes 28 inches in diameter and larger. Operates valves with handles that
close either toward the center of the dome or toward the dome wall. Several valve
handle adapters are available for use with common ball-type valves.
Just 3.5 pounds and requires only 1 ⅝ inch clearance (the thickness of an
operator's hand) between valve handle and nearest obstruction for operation.
Ideal for applications where air or nitrogen are readily available. Requires 90
psig to operate. Fail-closed design operates even if AC power or air pressure is
Easily opens valves with just a pull of the lever. Pushing the lever in the opposite
direction closes the valve. Reversible feature requires an additional air line (90
psig) and does not interfere with emergency operation mode. Designed for low-torque
*Designed in accordance with The Chlorine Institute’s guidelines for valve closure
Automatically responds to any alarm input, closing valves with 120 lb-ft of torque
in less than 10 seconds.
Robust motor requires no lubrication, and is encased by an aluminum cover for protection
and years of reliable service.
The UniPro™ QT Pneumatic Valve Closure System has been engineered, designed,
and field-tested to ensure reliable performance while reducing installation time,
maintenance, and material cost.
That’s Reliable Engineering.
The UniPro™ QT is designed to stand alone
as a complete system or to integrate and interface with existing unloading components.
The included air supply hose has a safety swing coupling to ensure a secure connection
between actuator and gas supply.
Easily mounts to the dome wall in seconds, without tools. Can be quickly removed
from the valve handle without detaching from the dome wall to facilitate manual
valve operation. Weighs just 28 pounds.
For use on containers of hydrogen chloride, vinyl chloride, monomer methyl mercaptan
and other pressurized hazardous gases.
The actuator is constructed of aircraft-quality aluminum and high-grade carbon
and stainless steels for maximum service life. A two-step polyurethane coating provides
The UniPro™ Control
Panel automatically activates the actuator to close the valve in the event
of a a non accidental release, car movement, fire alarm, seismic event, security breach, process
shutdown, or other monitored condition. You can also manually activate the system
by depressing the emergency stop button on the panel.
The air control unit supplies the proper amount of clean pressurized air to the
system. Available in two sizes to operate up to six UniPro™ actuators simultaneously.
The UniPro™ Pneumatic Valve Closure System is engineered to be the most versatile,
efficient, and reliable unit on the market. The system includes the actuator, control
panel, air control unit, and air supply hose.
