With a robust integral-to-body valve seat and optimized seating angles, triple eccentric butterfly valves offer reliable performance that can withstand high temperatures and pressures. Their zero leakage performance makes them ideal for demanding applications where leakage can have serious consequences, and their frictionless operation minimizes wear and tear, extending their lifespan and reducing maintenance requirements.Read more:shiphamvalves.com
Unlike other valve types, triple offset valves use a metal-to-metal seal instead of elastomers to ensure a tight shutoff. This design also enables them to operate in harsh environments, where elastomers are subject to deterioration over time. In addition, the geometry of their sealing components provides for smooth stroking and lower torque requirements for automation. Furthermore, the absence of cavities between the sealing surfaces eliminates the opportunity for debris to clog the mechanism, a common problem with gate and ball valves.
Maintenance Matters: Tips and Best Practices for Triple Offset Butterfly Valve Care
The triple offset valve’s geometry also guarantees non-rubbing rotation, meaning that the disc and seat never come into contact until the final stage of closing. This reduces the possibility of over-travel and guarantees repeatable, consistent sealing. In addition, the cam-action and right-angled conical design of the sealing surface prevents abrasion from damaging the soft seat seal.
Because they are suitable for use with a range of fluids, including abrasive and corrosive media, triple eccentric butterfly valves offer versatility in many applications. However, it is important to keep in mind that they require specialized engineering and precision machining. Additionally, they can be susceptible to vibration and noise, so maintenance strategies should be tailored to each specific system with attention paid to environmental conditions.
