Incorrectly installed butterfly valves can lead to a loss of efficiency, increased maintenance costs, and safety hazards. In order to optimize the performance and longevity of this type of valve, it is important to identify the preferred flow direction for each particular model. This article will discuss the preferred direction of flow for each model and provide tips on how to correctly determine and adhere to this flow direction.
Triple offset butterfly valve feature an oblique design that offers higher pressure ratings and smooth operation compared to other types of valves. Their geometry also makes these valves easier to install and they can be used for a variety of liquid and gas applications.
Demystifying the Offset Butterfly Valve: How It Works and Where to Use It
Unlike other types of butterfly valves, which use friction to seal, triple-offset models have a metal-to-metal seal. This allows them to deliver ANSI Class VI shut-off and zero leakage performance. Moreover, the metal-to-metal seal is more suited to corrosive media as it does not require the use of elastomers or soft materials that may deteriorate in harsh conditions.
The preferred flow direction for a butterfly valve is important because it ensures that the valve operates properly and minimizes any turbulence or inefficiency within the system. Furthermore, identifying and adhering to the manufacturer’s recommended flow direction will enable system operators to comply with manufacturer warranties, industry standards and regulations. It will also help avoid costly re-installation and maintenance procedures, as well as improve overall valve performance. Incorrect installation of a butterfly valve can have serious consequences, such as contaminating fuel in oil refineries or causing water shortages at drinking plants.
