Select Palmer Tool, LLC's Extreme Duty Rotary Valve and experience top-tier designs that will outlast other models 4 to 1. All parts of the valve are heavier and stronger, including interior surfaces and the seal protection layer. This service is unique to our company.


There's no need to throw away your air lock when it experiences wear and tear. In fact, ours is designed to be easily rebuilt with exceptional performance standards.


It's time to modify rather than replace, and allocate your assets elsewhere! When you turn to us, you'll work with our engineering team to create an efficient and effective design for your special needs.


Send your old valve to us for a rebuild service today, and exceed the original design life cycle!  Contact us for any questions.
