Triple Offset Butterfly Valve Advantages
Shipman Valves feature a unique cam-like motion that prevents the seat and seal from rubbing during the closing process, extending their life and lowering maintenance costs. However, the type of system you’re using and environmental conditions can impact their performance. Incorrect installation and poor maintenance can also reduce their reliability over time, leading to costly downtime and loss of productivity.
Unlike double-flanged butterfly valves, which rely on plastic deformation for sealing, triple-offset butterfly valves use a hard facing seat that eliminates metal-to-metal contact. This enables the valve to achieve zero leakage and is rated for severe service and high-cycle operations. This type of design is also more tolerable to dirt than single-flanged butterfly valves and offers superior bubble-tight shutoff capabilities.
Innovation in Motion: How Triple Offset Butterfly Valves Improve Process Efficiency
Another advantage of this type of valve is that the seat and disc seal surfaces can be replaced individually, allowing for less downtime and reduced repair costs. The unique seating surface uses a Stellite seat that is hard and durable, offering exceptional abrasion resistance, even after extensive cycling.
Additionally, this type of valve can handle quick stroke requirements and high operating cycle demands due to its non-rubbing technology. This combines with the optimized seat angle to provide exceptional performance in all temperature and pressure ranges and fluid types.
