Part Number Breakdown

  • 31A = 3/2-way direct-acting valve series
  • 2 = Threaded-port version

A = Normally Closed (NC)

  • V = FKM (Viton®) seal
  • 20 = 2.0 mm orifice

Typical Applications

  • Industrial automation
  • Pneumatic pilot circuits
  • Fuel and oil systems
  • Process control equipment
  • Packaging machinery
  • Beverage dispensing equipment
  • Water treatment systems
  • Air and inert gas control

Quick Summary

Key Advantage: The 31A2AV20 combines zero-pressure operation, high-temperature FKM sealing, and threaded-port installation, making it suitable for fuel oils, hydrocarbons, air, water, and industrial automation systems.
