氣動流量放大器 M4500A

　　Model 4500A Pneumatic Volume Booster

　　特性

　　Features

　　1.五個信號輸出比率滿足多數(shù)控制元素的要求。

　　Five signal to output ratios meet most control element requirements.

　　2.1”水柱壓力差的控制靈敏度允許在精密應(yīng)用情況下使用。

　　Control sensitivity of 1” water column allows use in precision application.

　　3.供氣閥和排氣閥很大，提供的供氣流量和排氣流量高。

　　Large Supply and Exhaust Valves seats minimizes air consumption.

　　4.軟的供氣閥門和排氣閥門座可最大程度降低空氣消耗。

　　Soft Supply and Exhaust Valve seats minimize air consumption.

　　5.平衡供氣閥可最大程度降低供氣氣壓不穩(wěn)的影響。

　　A balanced Supply Valve minimizes the effect of supply pressure variation.

　　6.補償管可最大限度降低流動條件下的下游壓力下降。

　　An Aspirator Tube compensates down stream pressure droop under flow conditions.

　　7.獨立的控制腔可將膜片與主流量隔開，以消除振蕩和噪音。

　　A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.

　　8.可選的遠程反饋端口可最大程度降低流動條件下的壓力下降。

　　Optional remote feedback port minimizes pressure drop at final control element under flow conditions.

　　9.可選的可調(diào)整旁通閥允許調(diào)整以獲得最佳動態(tài)響應(yīng)。（僅1:1比率）

　　Optional Adjustable By-Pass Needle Valve option includes bubble tight exhaust valve allows tuning for optimum dynamic response (1:1 ratio only)and cycle free operation with valve positioners.

　　10.機器構(gòu)造使您可以在不從系統(tǒng)上拆除4500A的情況下對其進行維修。

　　Unit construction lets you service the Model 4500A without removing it from the line.

　　11.適用于所有地區(qū)和省份的加拿大注冊號（CRN）認證。

　　Canadian Registration Number (CRN) certification for all territories and provinces.

　　M4500型氣動流量放大器是受歡迎的,由于其堅固的設(shè)計和高流量的經(jīng)濟方案。在它的先導(dǎo)式調(diào)節(jié)器設(shè)計,M4500處理250 psig,(17.0BAR),(1700 kPa)供應(yīng)壓力和有五個可用信號輸出比率來滿足大多數(shù)控制元件的需求。

　　The M4500 Pneumatic Volume Booster?flow amplifier is popular due to its rugged design and high flow of economic solutions. In its pilot regulator design, m handles 250 psig ( 17.0 bar ), ( 1700 kpa ) supply pressure and has five available signal output ratios to meet the requirements of most control elements.
