Product Overview

The electric PTFE-lined butterfly valve features a fully lined body and disc with virgin PTFE or FEP/PFA. The lining isolates the process media from the metallic body, providing outstanding resistance to strong acids (HCl, H₂SO₄, HNO₃), alkalis, and oxidizers.

Paired with a quarter-turn electric actuator, the valve delivers reliable on-off and proportional control for chemical, pharmaceutical, and high-purity systems with simple fieldbus integration.

Key Features

  • Full PTFE / FEP Lining: 5 mm lining on body and disc isolates corrosive media
  • Wide Corrosion Resistance: Suitable for HCl, H₂SO₄, HNO₃, HF, and strong alkalis
  • Electric Quarter-Turn: Compact electric actuator with adjustable speed and torque
  • Fieldbus Integration: Modbus, Profibus, HART protocols for plant automation
  • Replaceable Liner: Field-replaceable PTFE liner minimizes maintenance downtime
