5. The control valve has superb technology, superior structure, smooth flow, quick response, and can replace imported goods.
6. Il pressjoni qatra telf ta ' il li jirregola valve huwa żgħir , il output forza huwa stabbli , il - fluss koeffiċjent huwa kbir , u il - bla xkiel sezzjonijiet trasversali ta ' il-kanali huma ugwali.
7. The control valve adopts a pressure balance mechanism inside the valve, li makes the control valve responsive, precise in control, precise in control, and allows a large pressure difference.
8. The control valve body is designed according to the principle of fluid mechanics with a low-flow resistance passage of equal cross-section, and the rated flow coefficient is increased by 30%.
9. The control valve has the characteristics of small size, light weight, easy to use, large flow, energy saving, and high adjustment accuracy.

Jekk il-limitu limitu aġġustament tal-output shaft is improprju (il-limitu swiċċ atti wisq kmieni), it will affect the stroke adjustment. Therefore, before the output shaft is adjusted, in order to prevent the limit switch from acting too early, the fixing screw on the limit cam be loosened to delay the action of the limit switch.
Meta l-istatus switch is set to the "positive action state", (that is, as the input signal decreases, the output shaft moves upward), the input signal is is slowly reduced. When the input signal is is in the range of 3.7mA~3.95mA, adjust and tighten the outer limit cam to make the limit switch act and the output shaft stop move upward. Meta the status switch is set to the 22reverse action state", (that is, as the input signal increases, the output shaft moves upward), the input signals is upward), the input signal is slowly increased. When the input signal is in the range of 20.2mA~20.5mA, adjust and tighten the outer limit cam to make the limit switch act and the output shaft stop move upward.

Valv intern komponent materjali
Ewlenin metodi ta ' twebbis trattament
Komunement użat valv intern komponent materjali huma SUS304, SUS316, SUS316L, SUS410, SUS420, eċċ., u huma ipproċessati kif xieraq skond għal differenti fluwidu kundizzjonijiet. Għal kontroll kavità fluwidi, fluwidi li fihom solidu partiċelli, u temperatura għolja sitwazzjonijiet , huma għandhom ikunu imwebbsa. trattament biex testendi is-servizz ħajja ta ' il- il-valv .
Sħana trattament
a.304/316 solidu soluzzjoni trattament
Din serje ta ' materjali hija austenitic stainless azzar u huwa prinċipalment użat f' jaħdem kundizzjonijiet fejn il- medju huwa korrużiv jew f' temperatura baxxa sitwazzjonijiet. Meta il- medju huwa għoli korrużiv , soluzzjoni trattament trid tkun imwettqa barra. L-iskop ta ' soluzzjoni trattament huwa biex ittejjeb l-ebusija u korrużjoni reżistenza ta' il- materjal Temperatura firxa -196~530 grad
b.410/420 quenching and tempering treatment (quenching + tempering) The material of this series is martensitic stainless steel, which is an excellent cavitation-resistant material. It must be quenched and tempered when used in high-temperature and high-pressure difference situations. The purpose of quenching and tempering treatment is to greatly improve the hardness of the material and extend its service life under harsh working conditions. Temperature range -45~425 degree
c.17-4PH preċipitazzjoni twebbis trattament Tipi differenti u kwantitajiet ta' tisħiħ elementi huma miżjuda ma il kimika kompożizzjoni ta' stainless azzar, u differenti tipi u kwantitajiet ta' karburi, nitrides, karburidi u intermetalliċi komposti huma preċipitati through il preċipitazzjoni il preċipitazzjoni twebbes proċess, li mhux biss itejjeb is-saħħa ta' l-azzar but jinżammu biżżejjed ebusija. A tip ta' saħħa-għolja stainless steel, referred to as precipitation hardening. Temperature range -45~425 degree
Wiċċ twebbis trattament
Wiċċ sħana trattament huwa maqsum fi żewġ kategoriji : wiċċ estinzjoni u wiċċ kimika sħana trattament. a. Fjamma tisħin wiċċ tifi, kuntatt elettriku tisħin wiċċ estinzjoni , induzzjoni tisħin wiċċ estinzjoni% 2c eċċ. b. Karburizzazzjoni, nitriding, carbonitriding, kromju boronizing, ram infiltrazzjoni , eċċ.
Surfacing trattament
Stellite cladding (prinċipali komponenti Co, Cr, W) is a komunement użat twebbis trattament metodu bi eċċellenti korrużjoni reżistenza. Hemm hemm żewġ metodi ta ' Stellite surfacing: sħiħ surfacing u parzjali surfacing. Hemm le standard regolament għal l speċifiku surfacing metodu. Normalment jiddependi fuq il- differenti pressjonijiet u temperaturi ta ' il- fluwidu u jekk il- fluwidu fih partiċelli. It tipi ta ' surfacing iwweldjar huma kif kif isegwi 3a
