BLZ series flow indicator is a kind of equipment used to monitor and display the flow of fluid in the pipeline. It is usually used in industrial and engineering fields to ensure that the flow and direction of the fluid meet the design requirements. BLZ series flow indicators can measure all kinds of fluids, such as water, oil, gas and so on.

Vacuum butterfly valve is a kind of valve which is used to connect or cut off pipes in vacuum system. In the course of use, the vacuum butterfly valve has the following problems: 1. The multi-layer soft and hard stacked sealing ring is fixed on the valve plate, and when the valve plate is normally open, the medium forms a positive scour to its sealing surface, which affects the sealing performance; 2. Due to the limitation of structural conditions, the structure is not suitable for making valves with sizes below DN200. 3. The seal between the sealing surface of the valve plate and the valve seat depends on the torque of the transmission device to press the valve plate to the valve seat. When the flow channel medium is countercurrent, the unit positive pressure between the valve plate and the valve seat is less than the medium pressure, the seal begins to leak.

Vacuum butterfly valve is a kind of valve which is suitable for pipe connection or cut-off in vacuum system. It uses the rotary power electronic regulating valve drive mechanism to realize the control by converting the external power supply or input signal. The valve plate of the vacuum butterfly valve is cl/ed to construct a cl/ing valve plate sealing ring, which can be used not only in vacuum but also in low pressure.
