I have used several of these manual shut-off valves in air prep assemblies. While the construction seems very high quality and having not had failures I would say the value and overall quality is great. I do have two gripes about these which is why the Ease of Use rating is as it is. First, the handle is very difficult to turn, as with most types of these valves you need to push down and turn the valve. These are the hardest I have ever had to turn and I'm no slouch. Our operators would not have a chance with these. Second, the valves come with a mini lock and key for locking out the valve, while I appreciate the extra component it seems like a waste rather than designing the valve to work with standard lock-out locks.
I use this lock out valve on our machinery. They have performed as expected on the many machines Ive built. Youll also need to purchase the same size muffler (1/4 for 1/4 valve, 3/8 for 3/8 valve, etc.) to reduce noise when turning off the air supply via the valve. It is true that the unit includes a tiny lock, and the lock out tab is not large enough for a standard lock. However, one should be using a lock-out hasp with your lock, so that many persons can lock-out this device, and in this case, the tab is large enough to accommodate a hasp.
