COMPAC-NOZ® Nozzle Check Valves

Compac-Noz® valves have a shorter face-to-face design than standard check valves for applications where space and weight are primary focus and valve pressure drop is less critical.

Features And Benefits

  • Ease of installation and maintenance
  • Proven Reliability
  • Compact and lower weight
  • Lower pressure drop compared with standard Noz-Chek® offering
  • Face to face design to API 594 allows direct replacement of other valve types meeting this standard, without line modification, and provides axial check valve performance and reliability

Technical Details

DESIGN FEATURES

  • Compact design and short face to face to meet API 594
  • One moving part resulting in minimal wear and long service life
  • Quick dynamic response reducing reverse velocity and minimizing damaging water hammer
  • Short stroke to help in quick response
  • Choice of springs for specific critical velocity and valve response
  • Suitable for reciprocating compressor service eliminating chatter
  • Spring is internal and protected from process flow
  • Preferred in centrifugal compressor service
