Part Number Breakdown

  • 31A = 3/2-way direct-acting valve series
  • 1 = Subplate mounting version

A = Normally Closed (NC)

  • V = FKM (Viton®) seal
  • 25 = 2.5 mm orifice

Typical Applications

  • Industrial automation
  • Pneumatic pilot systems
  • Fuel oil and diesel systems
  • Packaging machinery
  • Dosing systems
  • Beverage equipment
  • Process control installations
  • Air and inert gas control

31A Series Comparison

Key Characteristic: The 31A1AV25 provides the highest flow capacity in the standard 31A direct-acting subplate-mounted range, while still operating with zero minimum pressure differential.
