“An added bonus is that PMM’s rotary valve airlock has reduced capital costs of future valve installations by 85%!”
“The installation and cost of ownership for the old (cast-iron) rotary valve was 12-times more than the PMV-8 while also requiring a large footprint and an even larger amount of utilities.”
“PMM’s Rotary Valve Airlock significantly reduced the amount of product lost.”
“The operators are happy with the airlock because it is easy to operate and performance does not degrade as fast as the old (cast-iron) rotary valve.”
“The PMV-8 reduced maintenance costs by $60,000 per year!”
“PMM’s PMV-8 wears much slower, which provides a predicable leakage and stabilizes the process.”
“Maintenance technicians enjoy the PMV-8 because it is so easy to maintain.”
“Our old (cast-iron) rotary valve had to be taken out of service (a lengthy process) and the nylon pads changed. When PMM’s rotary valve airlock does require maintenance, it just requires the removal of a few bolts, the barrel side rotated, and back into service. Super-fast and minimal downtime!”
“In comparison, the old (cast-iron) valve required maintenance every two months. PMM’s rotary valve airlock has been running for five months and there are no signs of wear.”
“Precision Machine & Manufacturing has offered superior customer support and has a knowledgeable and courteous staff who is a pleasure to deal with.”
“I look forward sustaining this sense of partnership as we work together to improve an already superior product for the price.”

“Due to the high wear rates of our old (cast-iron) rotary airlocks, we began to see material leakage and diminished airlock functionality almost instantaneously after being installed. We replaced these airlocks with PMM’s ultra-duty rotary valve airlock, and they ran for two whole years with zero maintenance issues, no loss in throughput, and no unscheduled downtime.”
“The old (cast-iron) airlocks were not rebuildable, so our only option was to replace them, which got expensive. Because PMM’s rotary valve airlocks are rebuildable, we could order direct replacements from PMM, schedule the maintenance, and have a quick shut down to quickly replace the worn components. Minimal downtime!”
“Precision’s rotary valve airlocks have MADE my plant what it is today!”
“PMM’s representatives are a trusted partner.”
“PMM’s representatives are continuously offering up suggestions and ways to improve our operations.”
“The coal mill valve was constantly getting clogged and required daily cleanings, which was a maintenance headache. We replaced the coal mill with PMM’s self-cleaning valve and it ran for 2-years with ZERO maintenance.”
“Precision’s rotary valve outlasted the old (cast-iron) valve, by four of the old to one of PMM’s!”
“The old (cast-iron) rotary airlocks did not allow for rebuilds so our only option was to replace them. PMM’s Rotary Valve Airlock is 100% rebuildable providing a superior cost of ownership!”
“The old (cast-iron) valve would begin wearing almost instantaneously after installation, which is a stark contrast to PMM’s rotary valve that ran for two years with no loss in airlock functionality.
