進(jìn)口自力式差壓調(diào)節(jié)閥
德國(guó)漢威HANWEI品牌:進(jìn)口自力式差壓調(diào)節(jié)閥(差壓升高閥開(kāi)),由控制閥門(mén)、執(zhí)行器和一個(gè)設(shè)定壓力的彈簧組成。適用于非腐蝕性的液體、氣體和蒸汽,在系統(tǒng)管道中起壓差控制的作用,當(dāng)壓差升高時(shí),控制閥開(kāi)啟。
控制閥參數(shù)說(shuō)明:
閥內(nèi)件特點(diǎn): 1、內(nèi)置波紋管,具有壓力平衡結(jié)構(gòu),靈敏度高
2、結(jié)構(gòu)緊湊,性能可靠,免于維護(hù)
3、采用標(biāo)準(zhǔn)模塊化設(shè)計(jì)
4、通過(guò)組合件,可以進(jìn)行多項(xiàng)組合控制

self-operated
differential pressure regulator (valve opened when differential pressure rises)
is composed of the control valve, actuator and a spring used for pressure
setting. It is suitable for controlling differential pressure in the pipes of
non-corrosive liquids, gases and vapors. When the differential pressure rises,
the control valve is opened.
Parameters of control valves:
Trim features: 1、Built-in bellows provided with pressure
balanced structure and high sensitivity
2、Compact structure, reliable performance, free of
maintenance
3、The standard modular design is adopted
4、Various combined controls can be carried out through
the assemblies
