Putzmeister S Valve Pipe Tube 

Putzmeister S valve pipe tube is component of 16Mn steel body, #38 CrMoAl shaft, chrome plate and inner wall hard surfacing by VAUTID 150. For this Putzmeister S-Valve tube, the inner pipe layer has high hardness and wear resistance; and the outer pipe layer has good toughness and strong impact resistance. Thus it can meet the requirements of concrete transportation.

Putzmeister S Valve Feature.

  • Reverse pumping is possible to solves the blockage problem without disassembling and cleaning of the pipeline.


  • S valve is especially useful for long pumping distances and high site with high pressure.


  • The S-valve has very few wear parts and all parts of the S-tube are easy to change.
