　　4.软的供气阀门和排气阀门座可最大程度降低空气消耗。

　　Soft Supply and Exhaust Valve seats minimize air consumption.

　　5.平衡供气阀可最大程度降低供气气压不稳的影响。

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

　　6.补偿管可最大限度降低流动条件下的下游压力下降。

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

　　7.独立的控制腔可将膜片与主流量隔开，以消除振荡和噪音。

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

　　8.可选的远程反馈端口可最大程度降低流动条件下的压力下降。

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

　　9.可选的可调整旁通阀允许调整以获得最佳动态响应。（仅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.机器构造使您可以在不从系统上拆除4500A的情况下对其进行维修。

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

　　11.适用于所有地区和省份的加拿大注册号（CRN）认证。

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

　　M4500型气动流量放大器是受欢迎的,由于其坚固的设计和高流量的经济方案。在它的先导式调节器设计,M4500处理250 psig,(17.0BAR),(1700 kPa)供应压力和有五个可用信号输出比率来满足大多数控制元件的需求。

　　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.
