I. Ubutumwa:
HCN Low Noise Cage Control Valve ni imwe mu mitwe ya CV3000, yashizweho cyane cyane kugabanya umwuzure wa fluid idashobora kwandura. Kugirango ikoreshe umwuka wo kugabanya umwuzure no kwandura, umusatsi ufite imyanda myinshi yo gusobanura kugabanya umwuzure. Umwuzure wa fluid ufite umwuzure wa S, kandi ufite umwuzure wo kugabanya umwuzure wa fluid iri hafi ya umusatsi, bityo valve ifite umwuzure muto, umwuzure mwinshi, no umwuzure muto. Umwuzure wa valve ufite umwuzure wa pressure balance, valve ikoresha actuator ya multi-spring diaphragm, ifite umwuzure muto, ifite umwuzure mwinshi. Ishobora kugabanya umwuzure wa fluid idashobora kwandura, kugirango ikoreshe umwuka wo kugabanya umwuzure no kwandura, umusatsi ufite imyanda myinshi yo gusobanura kugabanya umwuzure. Umwuzure wa valve ufite umwuzure wa pressure balance. Umwuzure wa fluid ufite umwuzure wa S, kandi ufite umwuzure wo kugabanya umwuzure wa fluid iri hafi ya umusatsi, bityo ifite umwuzure muto, umwuzure mwinshi, no umwuzure muto.

II. Imikorere:
Ubusobanuro: Metal valve seat: muto kuruta 0.01% ya umwuzure wa valve, bigenwa na ANSI B16.104-1976 IV class
Retracement: ifite positioner: muto kuruta 1% ya umwuzure wose,
idafite positioner: muto kuruta 3% ya umwuzure wose (LHA1 class muto kuruta 5% ya umwuzure wose)
Error isanzwe: ifite positioner: muto kuruta ±1% ya umwuzure wose,
idafite positioner: muto kuruta ±5% ya umwuzure wose
Icyo kwandikwa: ikoresha standard V-type PTFE filler
Umwuzure wo gushyiraho: 50:1 (0.25≤Cv≤14) cyangwa 30:1 (CV≤0.16)

III. Cv value na stroke:
