We are one of the few valve manufacturers performg Enterprise Resource Planng (ERP), -house fire safe and cryogenic testg, high pressure gas and low fugitive emission testg. Quality Assurance Neway's quality assurance is dedicated to the pursuit of zero defect valve supply to our customers. We have implemented a six sigma management TA Luft, and tested accordance with our customer s specifications and that comply with all ternational standards. With respect to the facts that the current dustrial standards do not always take to c o n s i d e r a t i o n t h e l i k e l i h o o d a n d consequences of possible deterioration service, related to specific service fluids or the external environment which they operate. Our customers are requested to keep an open le of counication with our engeerg department to identify and implement standards, that will provide valves with the possibility of deterioration service, so as to ensure safety over the valves expected lifetime. process order to contually improve our processes and management controls through the use of advanced statistical data analysis.

PDL PDL ~ ~ ~ The coon flow characteristics are: equal percentage flow characteristic (also named logarithmic characteristic), Learity (also named lear characteristic) and quick openg characteristic. When adjustg valve of lear characteristic is small openg, the relative varyg value of flow is large, and sensitivity is high, but it is difficult to control, however, when large openg, the relative varyg value of flow is small. When adjustg valve of equal percentage flow characteristic is small openg, the relative varyg value of flow is small, adjustg stability and mild, while large openg, the relative varyg value of flow is large. Note: When the range of sprg is from to kpa, air supply pressure is kpa G; when the range of sprg is from to KPa, air supply pressure is kpa G. Equal percentage flow characteristic is the direct ratio relationship between the relative varyg value of flow across the valve, caused by the relative varyg of displacement while valve openg and the relative flow the same spot.
