designed to remarkably reduce acousticnoise in services of compressible fluids
Model HCN Low-Noise Cage type Control Valve shave been designed to remarkably reduce acoustic noise in services of compressible fluids such as
steam, air, and natural gas. The cage has a large number of small holes and renders an ideal pressure reduction with a combination in two steps of
搑estriction?and 揹iffusion and expansion.?The fluid passage has been designed in S-figure shape for smooth flow of fluid with less pressure loss and a stabilizer is provided as a strainer for flow near the cage, thereby permitting a large Cv value.
The valve plug is of a pressure-balanced type which allows control of a high differential pressure with as mall actuating force. The actuator is a compact but high output diaphragm motor of a multiple spring type structured in a simple mechanism.
The model HCN valves, which are compact but of alow noise type and render high dynamic stability, are suitable especially for control of high temperature, high pressure or high differential pressure process lines.
