【Abstract】 To meet the requirement of differential pressure control, a new style pneumatic pressure control valve is developed for some pneumatic projection system to work under environment condition of variable pressure. The valve operates precisely with strong self adaptability, responds quickly due to small damping, and can be applied to large flow capacity and a lot of working conditions. Dynamic simulation technique is utilized to aid the design of the valve. Finally the experiment shows that the valve satisfies entirely the design requirement.更多还原
