Triple Offset Valve Benefits

triple offset valves

Triple offset valves are a type of butterfly valve that offers superior performance, durability and lower operating costs compared to traditional valves. These valves are commonly used in oil & gas, chemical processing plants, power generation facilities, and other industrial applications.

The valves use three offsets to achieve a smooth, durable, bubble-tight seal and eliminate the rubbing friction that occurs in traditional butterfly valves. These offsets are located in the shaft, seat, and cone axis and help to minimize wear between the sealing surfaces and provide durable performance throughout the valve lifecycle. Additionally, the valve design helps to reduce the sticking and binding of the disc and requires less operating torque from the quarter-turn actuator as a result of an optimized seating angle.

The Advantages of Triple Offset Valves in Industrial Applications

When the valve opens and closes, the cam action and right-angled conical seat ensure that the metal seal elements do not come into contact until the final degree of closing. This eliminates rubbing and provides bubble-tight shutoff and zero-leakage performance.

In addition, the angled alignment of the disc in relation to the seat eliminates a “blind zone”, which allows a full range of motion of the actuator with no need for manual operation. This feature also allows for easier installation and maintenance procedures. Additionally, the valve’s design eliminates rubbing between the seat and seal which reduces maintenance costs by eliminating the need for packing adjustment and extends overall valve life.

In addition, the abrasion-resistant valve seat is abrasion and corrosion-resistant and can be used in a wide range of operating conditions and temperature ranges. In fact, the valve is designed to withstand temperatures from -60 degrees Celsius to +840 degrees Fahrenheit and can be installed in harsh environments without fear of failure.
