        LCN Low-noise Cage Control Valve


        Overview
         The LCN low-noise cage control valve is a pressure-balanced control valve designed to reduce the compressible fluid noise.There are a number of symmetrical holes to reduce the pressure drop to apply to diffusion and expansion of gas. Besides it has lower noise than that of the LPC high-pressure cage valve. There is an S streamlined channel and a contra vane which improves the balanced flow ,so that they can reduce pressure drop and increase flow. The valve is equipped with the multi-spring diaphragm actuator for the compact structure and large output force. This product conforms to  GB / T4213-92.
