3500/05-01-01-00-00-00 In petrochemical and chemical installations, high performance butterfly valves, whether automatic or manual, play a key role in equipment operation, tight shutdown applications and equipment maintenance. Some key design characteristics and performance can greatly affect the performance and reliability of these valves. This article will help users make the right choice when evaluating the on-off valve selection scheme.
Advantages of high performance butterfly valves
High performance butterfly valves feature an advanced double eccentric seat design and a special sealing surface for bubble sealing, zero leakage, and a more compact design that significantly reduces installation space and costs less than ball or plug valves. This makes the high performance butterfly valve an ideal solution for most switching applications that require a tight shutdown with zero leakage.
The design of high performance butterfly valves varies. Emerson’s design i3500/05-01-01-00-00-00 mprovements allow valves to last longer while always providing tight shut-off performance, features that significantly reduce the cost of valves throughout their life cycle. This article discusses how to make the correct valve selection in different working conditions.
Innovative design of valve seat
The selection of a high performance butterfly valve suitable for the working condition begins with a careful evaluation of the design of the valve plate and seat. Obviously, long service life and tight shut-off performance is a key performance requirement, and the design of the valve and seat ultimately determines the performance of the valve in this application.
There are many valve plate materials, but should always consider some hardening treatment on the sealing surface to avoid wear, we think that the double eccentric design is better, it can ensure tight shut-off performance. The valve plate design must be paired with the seat design, and the seat can be shaped and adjusted to the 3500/05-01-01-00-00-00 valve plate while providing a long service life.
For many valve designs, tight shut-off and long service life are often mutually exclusive because the tighter the plate CAM is into the seat, the faster the seat will wear and degrade. Emerson’s design allows high performance valves to provide a bubble-level tight shut-off while providing significantly longer service life (see Figure 1).
