  • Maximum Operating Temperature:
    • 80°C (176°F) with PCTFE
    • 200°C (392°F) with PEEK 
  • Ports: 1/2" Female NPT, 1/4" Female NPT
  • Actuator: Knob, Antitamper nut
  • Materials of Construction:
    • Enclosure: 316 Stainless Steel
    • Seat: Fluorocarbon
    • Seal: PCTFE, PEEK
    • Stem: 316 Stainless Steel
    • Diaphragm: Alloy X-750
