Direct acting valve of simple design. The best choice for pressure control in branch lines and in front of small equipment

  1. High underpressure control accuracy even at low flow rates.
  2. Simple design, less prone to failure, easy maintenance.
  3. Compact and lightweight.
  4. Easy installation thanks to threaded connections.
  5. High wear resistance and strength of stainless steel valve and valve seat. A filter (60 mesh) is installed to protect the valve and valve seat from contaminants, such as deposits on the inner walls of the pipeline.
