As a control component in a fluid conveying system, the valve has functions such as cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and pressure relief. It is an indispensable control element in many working conditions.

Some valves are required to provide a high standard of operation and ensure a sufficiently long service life under high temperature, high pressure or high power loads, and some are required to be used in extremely cold environments. Depending on the use environment and the contact medium, some parts of the valve such as bushings, valve seats, valve cores and sealing rings require special materials to be customized for production. Stellite alloy products are widely used in valve components to ensure long-term stable use in extreme environments.

The main features of butterfly valves are:

• small operating torque
• small installation space 
•  lightweight

The butterfly valve is easy to combine with various driving devices, and has good durability and reliability.
There are a few different types of butterfly valves on the market, including the zero offset, double offset, and triple offset.

A kind of butterfly valve is a triple eccentric metal hard-sealed butterfly valve, the valve body and seat are connected components, and the sealing surface layer of the seat is made of high temperature-resistant and corrosion-resistant alloy. Stellite is a good choice. SYTOP has many years of experience in providing accessories for valve companies, if you have any needs, you can contact us at any time.
