Swagelok DE Series springless diaphragm valves are engineered to ensure easy installation, reliable performance, and superior purity in modular ultrahigh-purity gas delivery systems.

Key Features:

  • Valve body is made from 316L VIM-VAR stainless steel, ensuring high corrosion resistance and maintaining ultrahigh-purity standards
  • Designed for seamless integration into with 1.125 in. C-seal or W-seal modular gas systems
  • Fully contained PFA seat enhances purity by preventing contamination and offers improved thermal stability in critical applications
  • Available in both two-port and three-port configurations to meet various system requirements
  • Pneumatic and manual actuation options are available, offering flexibility in operation while maintaining a compact footprint
  • The actuator is fixed in orientation relative to the valve body, ensuring consistent installation and minimizing the potential for alignment errors
  • Corner chamfers on the valve body’s outlet side provide a clear visual indication of the flow direction, aiding in installation and system setup
