Stainless steel needle valve exterior feature presentation

Stainless steel needle valve simple structure, small size, resistance to fluid flow is small, the disadvantage is turned on or off too quickly, it will produce water hammer (when a sudden change in the flow velocity in the pipe pressure will rise) in the pipeline. Instrument needle valve Therefore should not be used in the main pipe valve, available in dry, or the end of the branch pipe for wash-use, flushing sewage effect. Including the development of iron and steel, sealing materials, and mechanical processing industries will have a significant impact on the level of technical parameters of the valve. Stainless steel needle valve of strength, ductility,High pressure ball valve  corrosion resistance, resistance to high pressure directly affects the valves, corrosion resistance; production level determines the valve sealing material applicable to medium and can withstand the pressure; precision machining is the impact of the interface seal, the valve head and an important factor in seating levels.
