Installation and Operation Tips for Chemical Gas Blind Flange Valves
Before installation, be sure to conduct a visual inspection. For valves with a working pressure exceeding 1.0 MPa and those capable of cutting off flow in the main pipeline, perform strength and tightness tests prior to installation; only after passing these tests are they permitted for use.

Safety Operating Requirements for Gas Blind Flange Valves
The setting of the electric power switch for the blind flange valve during actual operation should, as far as possible, prevent the valve from being left unattended. When personnel are operating the valve, they should stand in a favorable position and carefully monitor the surrounding environment for any changes.

Main functional parameters of the valve
A valve is a control component in pipeline fluid transport systems. It is used to alter the cross-sectional area of the flow path and change the direction of medium flow, performing functions such as guiding flow, shutting off flow, regulating flow, throttling, preventing backflow, diverting flow, or relieving pressure by overflow.
