Concrete Pump S Valve Assembly
High-Wear Switching System | Compatible with XCMG, SANY & ZOOMLION
Product Overview
The S Valve Assembly (also known as the S Tube Valve System) is the core switching mechanism inside the concrete pump hopper. It controls the alternating flow of concrete between the two delivery cylinders, ensuring continuous and stable pumping performance under high pressure. ARCHER delivers OEM-standard S-valves engineered for 37m to 63m truck-mounted pumps and trailer pumps, specifically optimized for SANY, XCMG, and ZOOMLION equipment.

Direct factory pricing and export-standard wooden packaging for distributors in the Middle East, Africa, and SE Asia.
S Valve Assembly FAQ
1. How do I confirm the correct S Valve model for my pump?
The selection depends on the Delivery Cylinder Diameter (200/230mm) and the Part Number (e.g., SANY 60000000). Please provide your VIN or photo for 100% verification.
2. What is the expected service life of ARCHER S-valves?
Under standard conditions, our valves handle 50,000 to 80,000 cubic meters. For high-abrasion stone mixes, we recommend our reinforced version.
3. Why is slurry leaking during switching?
Usually due to a worn Cutting Ring or Spectacle Plate. Replacing these wear parts or checking the swing arm pressure will resolve the issue.
4. Can you customize S-valves based on drawings?
Yes. We support OEM size and drawing customization for special high-pressure pumping systems or older pump models.
5. What packaging do you use for export?
We use Export-Standard Wooden Crates with anti-rust treatment to ensure the assembly arrives in perfect condition at your seaport or warehouse.
