Foxboro valves come in many different varieties, including check and butterfly valves. These valves are more used in life, then the following Xiaobian will introduce the advantages and disadvantages of these products.

Foxboro check valves are also known as check valves, back pressure valves, check valves and reverse flow valves. These valves are automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, which belongs to an automatic valve. Check valves can also be used to supply the pipeline where the pressure may rise to an auxiliary system that exceeds the system pressure. They can be divided into lift and swing types. The check valve is used in the pipeline system, its main role is to prevent the drive motor and pump reversal, to prevent the reverse flow of the medium, as well as the release of the container medium.

Foxboro butterfly valve is a valve that closes, opens, and adjusts the fluid channel with a disc type opening and closing element that rotates about 90°.

Foxboro butterfly valve features: 

① can be used for medium with suspended solid particles, according to the strength of the sealing surface can also be used for powder and granular media. It is widely used in gas pipelines and waterways of electric power, light industry, petrochemical industry, and metallurgical system. small size, simple structure, energy-saving, lightweight, not used in large-caliber valves; The flow resistance is small, open, and close quickly.

Disadvantages:  Due to the limitation of the sealing material and structure of the butterfly valve, it is not suitable for high temperature and high-pressure piping systems. General working temperature below 300℃, PN40 below; 

② Sealing performance relative to the globe valve, the ball valve is poor, so it is used for sealing requirements are not very high places;  the flow adjustment range is not large when open up to 30%, the flow will enter more than 95%.
