A.
While we understand the temptation for a quick fix, we definitely don’t recommend hitting your valve with hammers, wrenches, or whatever tools you have on hand. It only damages the valve and doesn’t help with material blockage. If you need help improving material flow, speak to one of our valve experts for recommendations specific to your application.

A.
When it comes to material shearing, the first thing we tend to look at is fill capacity. Factors like your material shape and size, equipment specifications, and conveying speed influence the right fill capacity to prevent jamming and shearing. Optional accessories like adjustable shear protectors, often recommended for materials like plastic pellets and sawdust, can be useful to help things keep flowing smoothly. A valve expert can give you more specific guidance based on your application.
