Stop Dangerous Leaks of Extremely Hazardous Gases Where They Occur

Avoid production slowdowns, operator injury, or lengthy and expensive environmental cleanups by stopping dangerous chemical leaks with the UniPro^TM LTR Pneumatic Valve Closure System. The only low-torque, 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. Like the UniPro LT, the UniPro LTR is specifically designed for "low-torque" valves to prevent damage to the valve seat. 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 and reliability.

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

FOR LOW-TORQUE, PLUG-TYPE ANGLE VALVES

Designed to close a variety of low-torque, plug-type angle valves on railcars and tank trucks. These soft-seat valves are often marked with warnings to operate by hand only. Not intended for use on any high-torque valves that require tools to close and seat completely.

PNEUMATIC

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 lost.

Reversible

Easily opens valves with just a pull of the lever. Pushing the lever in the opposite direction closes teh valve. Reversible feature requires an additional air line (90 psig) and does not interfere with emergency operation mode. Designed for low-torque valves only.

LOW MAINTENANCE

Robust motor requires no lubrication, and is encased by an aluminum cover for protection and years of reliable service.

Patent Pending

POWERFUL

Automatically responds to any alarm input, closing valves with 30 lb-ft of torque in less than 10 seconds.

EASY TO INSTALL

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 only 17 pounds.

ADAPTABLE

Various valve adapters are available depending on your particular application (valve handle configurations, material hazards, spark resistance), and all easily attach/detach with a single hitch pin.

The UniPro^TMLTR 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^TM LTR 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.

The UniPro^TM LTR is designed to stand alone as a complete system or to integrate with existing unloading components. The included air supply hose has a safety swing coupling to ensure a secure connection between actuator and gas supply.

Designed for Durability

The actuator is constructed of aircraft-quality aluminum and high-grade carbon and stainless steels 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.

UniPro Control Panel - automatically activates the actuator to close the valve in the event of an emergency.

Maximum Control

The UniPro^TM Control Panel automatically activates the actuator to close the valve in the event of a gas leak, 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.

Air Control Unit

The air control unit supplies the proper amount of clean pressurized air to the system. Available in two sizes to operate up to 12 UniPro^TM QT actuators simultaneously.

Versatility

The UniPro^TM name represents a whole family of pneumatic actuators for railcar and tanker applications, including the standard, reversible and low-torque models, all designed for plug-type valves, plus a quarter-turn model specifically designed for ball-type valves. The control panel, air control unit, and all optional system components work with any of our pneumatic actuators.

UL - CUL Approved

Powell Valve Closure System control panels (UniPro, MaxPro RA & E-Pro) are listed by Underwriters Laboratory to UL 508A for Enclosed Industrial Control Panels. Panels are listed by Underwriters Laboratory bearing the UL & CUL mark for use in the United States and Canada markets. In applications where a CSA listed control panel in Canada is required, please contact Powell engineering for further information.
