- Características principales
- 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
