功 能
高流通能力—高效軸流式設(shè)計(jì)帶來卓越的高流通能力。
嚴(yán)密關(guān)斷—閥體上帶聚四氟乙烯 (PTFE)閥座的節(jié)流套設(shè)計(jì)確保正向關(guān)閉。
精確控制—模壓指揮器閥膜提供窄比例帶,主閥膜上的出口壓力取壓確保卓越的控制靈敏度。
快速響應(yīng)—設(shè)計(jì)為可符合渦輪啟動(dòng)和燃?xì)鈶?yīng)用嚴(yán)格的響應(yīng)速度要求。
完全無大氣排放—利用指揮器作用式控制系統(tǒng)將所有氣體排放至下游系統(tǒng),因此不會(huì)將任何有害廢氣排放至空氣中。
高量程比能力—超大尺寸的閥膜和獨(dú)特的指揮器系統(tǒng)可實(shí)現(xiàn)高量程比,面對下游流量需求的大幅變化,可為系統(tǒng)內(nèi)提供出色的壓力控制。
所需的安裝空間極小—由于主閥設(shè)計(jì)采用了執(zhí)行機(jī)構(gòu)彈簧,310A 型較其它功能相近的調(diào)壓器所需的安裝空間更小。
在嚴(yán)酷的工況下具有很長的使用壽命—金屬塞設(shè)計(jì)可使顆粒和碎屑偏離軟閥座,提供卓越的顆粒侵蝕阻力,延長使用壽命。

Type 310A fuel pressure regulator is used for high-pressure applications which require fast response such as fuel gas supply to a gas turbine or other large volume applications. The Type 310A fuel pressure regulator includes one Type 32A pilot assembly mounted on the main valve for pressure reducing or wide-open monitoring applications. Type 310A fuel pressure regulator has accurate control, tight shutoff, high capacity, and fast speed of response.
Features
High Capacity—The highly efficient axial flow design produces exceptionally high capacities.
Tight Shutoff—Throttling-sleeve design with Polytetrafluoroethylene (PTFE) seat in the body ensures positive shutoff.
Accurate Control—Molded pilot diaphragms provide a narrow proportional band and registration of outlet pressure on the main diaphragm allows excellent control sensitivity.
Fast Speed of Response—Designed to meet stringent speed of response requirements for turbine startup and fuel gas applications.
Absolutely No Atmospheric Bleed—Eliminates nuisance and wasteful bleed gas to atmosphere by utilizing a pilot-oper |
