| According to the relevant news: Japan Bar Valve developed a new product - wafer type double plate (Double Plate) check valve "MKT" series, equipped with even fluid flow rate or fluid fluctuations will not cause chatter (Chattering The new structure will be available. This product not only solves the chattering problem, but also achieves the shape and strength that can withstand high flow rates, so that the originally required pressure reducer-based expansion pipe and the straight pipe on the primary side of the check valve are not required. As a result, the piping space around the pump is reduced by 7 to 80%. Because the product can withstand high flow rates, it can be mounted directly on the pump. It is possible to use a check valve whose diameter is reduced by 2 to 3 sizes. In addition, since the valve plate is also miniaturized and lightened and the moment of inertia is reduced, the pump is quickly "fully closed" when it stops operating to prevent water hammer. The spring element is used differently depending on the installation method of the Up Flow, Down Flow, and horizontal piping, and the flow rate. By selecting the most suitable spring, the valve can be accurately placed in the fully open position. The valve diameters are 50mm, 65mm, 80mm, 100mm, 125mm, 150mm, 200mm, 250mm and 300mm, and the maximum working pressure is 2.0MPa. The flow rate range is from 0.5 to 12 m/s, and the use temperature range is from 0 to 100 °C. | |
