Application

Tips: What are the advantages of a triple offset butterfly valve?

• Geometric Design: The design of the sealing components takes up a right-angle cone shape. Resulting in a cam-action and right-angled design where the sealing components are never in contact until their final degree of closing. Thus, enabling a repeatable sealing and an extended valve life because of its friction-free nature. In addition, the friction-free stroking throughout the valve allows for a relatively lower torque actuator to operate this type of valve. Such a design makes it ideal for automation.
• Metal-to-Metal Seal: Because of the frictionless sealing mechanism, triple offset butterfly valves use a metal-to-metal seal. This enables a tight shutoff in high-pressure and high-temperature systems. Applications that use friction in sealing often use elastomers or soft material for the valve trim, which may deteriorate with increasing temperature or when the valve is subjected to corrosion. But with the triple offset, corrosion-resistant alloys can serve for both the valve disc and seat, to deliver zero leakage performance.
• Absence of Cavities: In a triple-offset valve, there are no cavities between sealing components. Therefore, there is no room for debris to clog and disrupt the sealing mechanism, unlike gate and ball valves. This minimizes maintenance costs and extends the valve life.
