Valve replacement provides cost savingsThis is in regards to Simple Solutions from a past issue, titled "Controlling pressure build up in air motors." For your information, a 1 hp air motor will use 6 to 10 cfm at 90 to 100 psi. Drilling a 1/8 in. hole in the air line at these psi will pass 25.
Valve replacement provides cost savings
This is in regards to Simple Solutions from a past issue, titled "Controlling pressure build up in air motors." For your information, a 1 hp air motor will use 6 to 10 cfm at 90 to 100 psi. Drilling a 1/8 in. hole in the air line at these psi will pass 25.8 cfm at 4.5 cfm per hp. The hole is using 5.73 hp. Converting the horsepower to kW and using $0.045/kW gives a cost of $0.192/min. or $11.52/hr. How about replacing the valve for $50? — Henry Raymond
I would not recommend that anyone drill a hole in a pipe to prevent the possible problem discussed in the subject article. The proposed solution would leak expensive compressed air during the productive use of the air motor and is very wasteful. A three-way valve that exhausts the downstream air would achieve the same result. But the best solution is to repair all the leaks, not to create them.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
