PTFE Miniature Solenoid Valves

iPolymer PTFE Miniature Solenoid Valves include 2-Way and 3-Way Valves with a variety of body configurations, seat sealing methods and solenoid coils. The valves feature PTFE wetted flow paths that are optimized for ultra clean and chemical applications. These ultrapure PTFE Valves offer precision performance under extreme conditions. iPolymer also custom configures 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.
