LPH13 Diaphragm / Piston Low Noise Cage Guided Control Valve catalogues


LPH15 low-noise cage type control valves with labyrinth cage are designed to reduce acoustic noise in services of compressible fluids such as steam, air and natural gas. The cage employs multi-hole structure and reduce noise by ideal pressure reduction with a combination in two steps of restriction" and "diffusion and expansion". The valve plug employs a pressure balance function to control high differential pressure fluid with small actuator force. The control valve realizes seat leakage performance as single seat valve by seal-ring structure.

In addition, the control valve is equipped the cage plug with a scraper ring to prevent a malfunction caused by foreign object enter between the cage plug and the cage. The control valve is widely applicable for reliable control of high or low temperature, high differential pressure process lines where dynamic stability, low noise are required.
