Tank Truck/Railcar Unloading - UniPro™ Valve Closure Systems

What if I only get tank cars or tank trucks with soft seat angle plug valves?

Answer:

If you never have to operate ACF valves, the UniPro™ LT is the appropriate actuator. Operating at 90 psig, it will deliver only enough torque to operate the soft seat valves that require no more than hand tightening.

It cannot be used on high torque ACF or similar valves requiring more than 30 lb-ft of torque to operate.  In this situations, the UniPro Standard or UniPro R would be used.
