It sounds to me that the seals inside are stuck to the plastic slider it self inside the valve body. What I did with mine when they became hard to open I drilled a small hole in the top of the valve body and screwed in a grease fitting. Using a regular grease gun the grease under pressure has no where to go but through the seals freeing the seals from the blade slider inside. It is usually the black tank that gets hard to open. When ever the handle gets hard to open I pump some grease into the fitting and all is well for a couple of more years. If you pull to hard on the handle and the threads pull out of the slider there is no other way to get that slider to move. I hope this helps. It is a very easy fix.
