Description
If you’ve ever dealt with air brakes that won’t release properly or feel spongy, moisture in your air system could be the culprit. This drain valve is your first line of defense against water buildup that can freeze in winter or cause corrosion year-round. It’s a simple but critical component that keeps your air brake system working reliably when you need to stop that tractor.
What You’re Getting
- Manual drain function lets you purge moisture and contaminants from your air system
- Threaded design provides secure mounting and easy operation
- Built to handle the pressure and temperature swings of air brake systems
- Direct replacement for original equipment—no modifications needed
- Quality construction that won’t stick or leak under normal operating conditions
Built for Real Farm Work
This drain valve fits a wide range of Deutz tractors from compact utility models to larger field machines. The Agroprima and Agrostar series are popular choices for mixed farming operations, while the DX series tractors handle everything from loader work to heavy tillage. All these machines depend on reliable air brakes for safe operation around the farm and on public roads.
Made to Last
Air brake components take a beating from constant pressure cycling, temperature changes, and exposure to moisture. This valve is engineered to handle those conditions without seizing up or developing leaks. The threaded body provides a solid connection point, while the internal components resist corrosion from condensation that naturally occurs in compressed air systems.
Good to Know
Make draining your air tanks part of your regular maintenance routine—weekly is ideal if you’re using the tractor daily. Always drain when the system is at operating pressure for best results, and listen for the air flow to stop completely before closing the valve. If the valve gets stuck, a little penetrating oil usually frees it up, but don’t force it or you might damage the threads.
