OpTEā¢ Triple Eccentric Butterfly Valve
The OpTE Triple Eccentric, or Triple Offset, Butterfly Valve is a robust isolation valve providing absolute zero leakage. Originally designed for steam isolation applications ranging from vacuum to high-pressure, the OpTE is now commonly used in liquid as well as gaseous services. The triple offset disc design is torque-seated and inherently fire-safe. Trimteck specializes in modifications of this design to handle extreme temperatures.
