Features

• Straight-through flow:
  • reduces cell shear
  • eases draining and cleaning
  • provides high Cv, uniform flow.
• Boreline seals virtually eliminate entrapment areas.
• Spring-loaded stem controls closing force, enhancing pinch tube element service life.
• Valve offers excellent drainability when properly oriented.
• Compact, three-piece construction allows space-efficient system layout.
• Lightweight (1.75 lb [0.79 kg]), high-strength PEEK body provides low thermal conductivity and resists corrosion.
• Valve offers secondary packing/body seal with telltale leakage detection port.
• Manual and pneumatic actuation available.

Testing
Every Swagelok pinch valve is factory tested with nitrogen at its maximum pressure rating to a maximum leak rate of 0.04 std cm³/min at the seat and shell. Body seals are tested with helium at 10 psig (0.68 bar) to a maximum leak rate of 1 × 10^–5 std cm³/s.

Cleaning and Packaging
Every Swagelok pinch valve is cleaned and packaged in accordance with Swagelok Standard Cleaning and Packaging (SC-10).
