SP7 (BLV-201) Valve for Tractor Inner Tubes, Screw-In
Specialised valve, enhanced durability | TRCH3 core and cap included | Sold per piece
The SP7 (BLV-201) is a screw-in tube valve designed specifically for agricultural and tractor vehicles. It stands out for its enhanced durability and resistance, and for its TRCH3 core, which — like other water-ballast valves in our range — lets the tyre be filled with air or with water.
What this valve is for
The SP7 screws into the hole in the tube. The TRCH3 core is removable, so the tyre can be filled with water when needed to add wheel ballast — a standard practice during heavier field work that improves traction. Once filling is done, the core is screwed back in and the valve is closed with the included cap. The high-quality materials the valve is made from give it durability and an airtight seal, even under the intensive use typical of farm machinery.
Design and construction
Simple fitting into the tube hole.
Allows water-filled wheel ballast.
Built for agricultural vehicles.

Frequently asked questions
What is the TRCH3 core in this valve for?
It lets the same tyre be inflated with air or filled with water for wheel ballast. The core is unscrewed while filling with water and screwed back in afterward.
How does this valve differ from a standard tube valve?
The SP7 (BLV-201) is a specialised valve built for agricultural and tractor vehicles, with enhanced durability and resistance plus a TRCH3 core for water-filled wheel ballast — standard tube valves usually don't have this function.
Does the cap come included?
Yes, the valve is sold together with a cap that protects the core and keeps the valve airtight.
What if the TRCH3 core wears out?
The TRCH3 core can be replaced on its own, without replacing the whole valve — it's available in our store as product 6-17-587.
