Hangzhou valve focuses on scientific and technological innovation and cooperation in production, learning and research. Currently, it has more than 70 national patents, including temperature reduction and pressure reducing devices, safety valves, among which, 8 patents are invention.
CRITICAL CONTROL VALVE
|The cage guided feed water control valve is basically a single seat structure but featured with cage design. The cage has favorable Interchangeability, be reached different flow characteristics including linear, equal-percentage and quick open, to get much higher precision of controlling.
The most excellent of cage guided control valve is its balance characteristic, for plug balance port’s function, fluid pressure acted on static unbalance force of plug, it reduced unbalance force, then valve can be configured actuator smaller than conventional control valves.
With balance type characteristic, LT661Y/961Y feed water control valve is designed to focus on high pressure drops, effectively reduce the effects of cavitation and the noise in the high pressure drops services which is especially suitable for feed water application.
