BLAC INC. constructs two different types of butterfly valve actuators for FCCU applications depending upon the size of output torque delivered. The smaller sizes are built completely self contained and enclosed and operating with the internal components all running in oil. In general, all BLAC INC. butterfly valve actuators provide Zero Backlash Design, 10 Year Life Seals, Guarantee Not to Leak for 6 Years, Matching Torque Curves in Both Open and Closing Directions.
The smaller actuators are sized up through 600,000 in-lbsf (67,810 Nm). These actuators are unique in the FCCU Expander turbine industry with the features that are offered.
The larger actuators are sized as greater than 600,000 in-lbsf (67,810 Nm). These actuators are unique in the FCCU Expander turbine industry with the features that are offered.
The larger style actuators are open design concept and reflect similar technologies that BLAC INC. builds in the slide valve type actuator systems. These systems are all highly reliable and have set the standard in the industry since 1992.
