Product Details

ZXPII/ZXMII  series low noise cage type control valves are featured with very low operating noise (aerodynamic noise) when they are used to handle compressive fluids, such as steam, air fuel, gas, ethylene gas, etc. The cage and valve plug are of multiple hole construction. The components "restriction", "divergence", "expansion" are laid out in a rational manner to accomplish low noise pressure reducing action. Valve plug is designed to produce no torque vibration. Valve plug is held directly inside the cage to resist vibration and wear. The modular concept in design and construction allows component interchangeability with those of the VDC cage valves. Thus, valves can be disassembled and reassembled resulting in quick maintenance, and minimising down time.
