A soft sealing flanged concentric butterfly valve (also known as a “center-line butterfly valve”) is a quarter-turn rotary valve designed for on/off or...
Single eccentric butterfly valve
In order to solve the extrusion problem between the disc and the valve seat of the concentric butterfly valve, the single eccentric butterfly valve is produced. Dis...
The flow rate and velocity of the valve mainly depend on the diameter of the valve, and are also related to the resistance of the structure of the valve to the medium, and at the same time have a c...
The valve is a tool used in the transmission and control of gas and liquid with at least a thousand years of history.
At present, in the fluid pipeline system, the regulating valve is the control e...
