Conditions Instrument needle valve inspection

Instrument needle valve is a simulation test in the normal state. This state should be able to cover all water department environment. Dynamic test valve executive function Another very important point is that the test voltage, what kind of voltage the most appropriate? High pressure ball valve Smart meter in every one has a same function, that is, when the battery voltage is below the set value, the microcontroller will command the valve closing function is activated, Valve manifolds when the battery voltage is the lowest in the smart meter voltage Instrument needle valve, also that is, the final action is the lowest setting off valve in the battery voltage. The task of the truth is by reversing valve to the valve dredge or occlusion. Instrument needle valve switch is lightweight, small size, can be made very large caliber, reliable sealing, simple structure, Instrument needle valves convenient maintenance, regular spherical surface and seal in the closed condition, can not easily be eroded media, in all sectors lost universal use.
