EGP = Engineering Grade Plastic This valve is used for levelling purposes in air suspension systems. Variations in the height of the chassis resulting from load variations are equalized by inflating or deflating the air suspension bellows in proportion to the respective loads carried by the vehicle. For increasing the stability in curves there is the possibility to get this valves with a cross restriction between the both delivery ports. For vehicles with a raise/lower valve it is possible to install a levelling valve with a height limitation device. If the chassis will be raised by using the raise/lower valve the height limitation device will cut the pressure for the port No. 1 of the raise/lower valve when the maximum height of the chassis is reached, so that the chassis cannot be raised anymore. 高度阀的作用是用于空气悬架系统中高度控制．根据车辆的载重情况，通过向空气悬架气囊充气和放气，来控制车辆底盘的高度．为了增加转弯时的稳定性，高度阀两出气口之间可有横向限流作用．对于具有底盘提升阀的车辆来说，可安装带高度限制装置的高度阀．底盘通过提升阀提升高度时，如果底盘高度达到最大时，高度限制装置会切断提升阀１号口的气压，底盘不能再升高.
