To improve the anti-corrosion effect of needle valve type, valve for the modern production practice, has strong professional feature, the actual design of stainless steel needle valve is more accurate and efficient, the pursuit of higher quality, all needle valves and valve, anti-corrosion standards as an important condition, it is more important is the role of anti-corrosion. The pursuit of...

Stainless steel needle valve type of corrosion protection, but also in the hydraulic fitting manufacturer actual production of the applied in different circumstances, to consider the actual use of the temperature and humidity standard, consider medium corrosion level. Such as under general often wet valve production, the use of non-metallic materials of its durable products,...

Valve parts is difficult due to the valve installed in the machine tool structure and complicated shape, some valve parts wall thin, long and thin piece, the poor rigidity. On the machine tool processing, the positioning and clamping are difficult, so often require complicated special fixture. Sometimes low precision positioning base surface, the surface roughness is higher, sometimes even...
