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...

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...

Needle valve is a kind of can accurate regulating valve in a wide range of USES, such as flame cutting cutting distance, is used to regulate the knob to the flame temperature of the needle valve, needle valve and instrument is an important part of the instrument piping system. Cut-off valve and ball valve is used to open or cut off the line.The purpose of any valve are cutting fluid. Depending...

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,...

Bellows type needle valve adjusting range is big, is used to working temperature t the 200 degrees of clean medium such as air and steam piping, cannot be used for the liquid pressure, more cannot be used for containing solid particles medium in pipeline. When installation usually have filter in front of the pressure reducing valve, to ensure the pressure reducing valve sensitive and...

Needle valve is a throttling valve, adjusting precision is higher. Valve needle, along the flow direction of movement, change the flow area, to truncate or flow adjusting valve. Needle valve is a kind of fine-tuning valve, the valve plug for needle, mainly used for adjusting the gas flow. Fine-tuning require valves open mouth increases gradually, from closed to open for finely adjusted.Needle...
