At Armstrong/Weatherly we have been involved in the success of many projects in Texas. One of the many industries we touch is the concrete industry.
With the type of issues this plant was having, we recommended Posi-flate butterfly valves as a solution. They were installed on a pneumatic railcar unloading system that handles cement. These valves operate 20 hours a day, five days a week.
HERE WAS THEIR PROBLEM
Cement plant was dissatisfied with the type of butterfly valves installed on their pneumatic railcar offloading system. The facility unloads cement from railcars through a boot-lift into a dense phase pneumatic conveying system. The temperature of the cement as it passes through the valves ranges from ambient to 150 degrees+ F. During peak periods, the valves are required to operate 20 hours a day, five days a week.
The butterfly valves that were installed on the system were exhibiting sealing problems and premature wear. Maintenance was very costly since spare parts were not an option and the valves had to be replaced as they wore.
HERE WAS OUR SOLUTION
The decision was made to replace all their butterfly valves with Posti-flate butterfly valves. Unlike the previous product they had in place, spare parts are readily available and can be easily replaced on the Posi-flate valves.
They purchased 3", 6", 8" and 12" Posi-flate valves for the pneumatic railcar unloading system. One of the valves operates as a hopper, totally enclosed, with remote pilot operated controls.
RESULTS = REDUCED COSTS
The Posi-flate butterfly valves have outlasted the previous valve product three to one. The investment for changing from a non-performing product to Posi-flate butterfly valves recovered in less than two months and maintenance costs have been reduced by nearly 67 percent!
