Belangrijkste kenmerken

Triple offset design – No friction during opening/closing; long service life, low torque
Double flange connection – Can be independently installed between pipeline flanges; easy maintenance; suitable for large bore and high pressure
Bi-directional zero leakage – Metal hard seal for high temperature, high pressure, corrosive and abrasive media
Motorized actuation – Enables remote on/off, local operation, and signal feedback for automated systems
Low operating torque – Lower than conventional hard-seal butterfly valves; allows more economical actuators
Fire safe design (optional) – Compliant with API 607
