日本巴阀门开发出一种新型产品—晶圆型双板(DoublePlate)止回阀“MKT”系列，配备了即使流体流速较快或流体波动时也不会引起颤动(Chattering)的新结构将已面世。该产品不仅解决了颤动问题，还实现了能够承受高流速的形状和强度，这样原来需要的基于减压器的扩管和止回阀一次侧的直管就不需要了。这样一来，泵周围的配管空间就削减了7～8成。 由于产品可承受高流速，因此可直接安装在泵上。便可使用口径比原来减小2～3个尺寸的止回阀。另外，因为还实现了阀板的小型化和轻量化并降低了惯性矩，所以泵停止运转时就会快速地“全闭”，以防止出现水锤现象。 弹簧元件根据上流(UpFlow)、下流(DownFlow)以及水平配管等的安装方式和使用流速而区别使用。通过选定最合适的弹簧，可准确地使阀门处于全开位置。阀门口径分别为50mm、65mm、80mm、100mm、125mm、150mm、200mm、250mm以及300mm，{zg}使用压力为2.0MPa。使用流速范围为0.5～12m/s，使用温度范围为0～100℃。

Japan, Pakistan to develop a new product valve - wafer type dual plate (DoublePlate) Check "MKT" series, equipped with fast or fluid even if the flow rate fluctuations will not cause fibrillation (Chattering) The new structure will be has been available. The product not only solved the vibration problem, but also realize that can withstand high-velocity shape and intensity, so that the original pressure reducer based on the needs of the expanding tube and check valve on one side of the straight pipe is not necessary. As a result, pump piping around the room on the reduction of 7 to 8 into. As the product can withstand high velocity, it can be directly installed on the pump. Can use the reduced diameter than the original size of 2 ~ 3 non-return valve. In addition, because valve plate also achieved the miniaturization and weight and reduces the moment of inertia, so when the pump stops will be quickly "full closure" to prevent water hammer phenomenon. Spring element with upstream (UpFlow), downstream (DownFlow) as well as horizontal piping, etc. Installation and use of flow and the indiscriminate use. Through the selection of the most suitable spring can be accurately so that the valve in the fully open position. Valve diameter, respectively 50mm, 65mm, 80mm, 100mm, 125mm, 150mm, 200mm, 250mm and 300mm, maximum operating pressure of 2.0MPa. Using the flow rate range of 0.5 ~ 12m / s, using the temperature range of 0 ~ 100 ℃.
