iPolymer Miniature Solenoid Valves

Miniature Solenoid Valves

Our iPolymer Miniature Solenoid Valves include 2-Way and 3-Way Valves with a variety of body configurations, seat sealing methods and solenoid coils. The all PTFE wetted flow path design is optimized for ultra clean and chemical applications. iPolymer Miniature Solenoid Valves, with a 100% wetted flow path, offers precision performance under extreme conditions. iPolymer also custom configures these valves for specific application requirements, including; vacuum applications and unique manifold configurations.


  • PTFE design optimized for ultra clean and chemical compatibility.
  • Fast, accurate and repeatable coil response time from proven technology.
  • High Duty Cycle Rated with controlled ambient temperatures.
  • Valve seat and diaphragm designed for positive flushing and tight shut off.
  • Non porous diaphragm configured to completely isolate solenoid coil from media.
  • O-ring seat configurations for vacuum and complex media applications.
  • Designed for aggressive media and elevated temperature.

Standard Options

  • 12 or 24 VDC. 24, 115, or 230 VAC.
  • 3-Way, 2-Way NC, or 2-Way NO configurations.
  • Flare, compression tube or FNPT pipe styles.
  • EPDM, Viton, Aflas, or Kalrez O-ring.
  • Optional PTFE hard seat.
  • For 3-way valves, select from 4 orientations

Special 20 VDC Low-Watt Coil

iPolymer miniature solenoid valve can be configured with a special 20 VDC Low Watt Coil (6.7W). This configuration is available for 1/8, 1/4, and 3/8-in body sizes with O-ring seat seals.
