Siemens 41-2550精密减压阀Series 41特点和优点：

◆多级低下垂精密调节器在流量和供给压力的大范围变化中保持恒定输出

◆环氧粉末涂料提高了耐腐蚀性

◆调节压力[1“到450 psi]的广泛选择提供了应用的多功能性

◆零压力调节系统提供可靠的免维护操作

Siemens 41-2550精密减压阀Series 41产品说明：

Series 40、Series 41和Series 42型精密压力调节器控制需要精确可靠调节的应用中的空气压力，例如气动仪表回路、试验台、生产检查夹具和工业空气表。因此，它们适合于死胡同服务，流量可达110 scfm。

一个*的，两阶段试点设计提供了的准确性。坚固的结构，没有连杆、杠杆、枢轴或其他产生摩擦的构件，确保可靠、免维护操作。这些特性使调节器能够保持恒定的输出压力，不管怎样即使是流量或供给压力的变化。事实上，使用型号40、41或42的调节器实际上是一个独立的压力控制器，通过一个内置的高增益气动放大器来操作其供应柱塞阀。

一个精细转动的精密螺钉用于手动加载量程弹簧，该弹簧可设置调节压力。当顺时针转动调节旋钮时，增加的弹簧力施加在顶部隔膜组件上，从而减小喷嘴间隙并增加先导压力。因为先导压力的来源是通过节流阀流向先导压力室的供气螺钉，升高的先导压力迫使排气隔膜总成向下。此动作关闭排气口，接触并移动阀柱塞，从而打开供油口。这增加了调节输出，也反馈到顶部隔膜组件。当顶部隔膜组件的反馈力等于范围弹簧力时，调节器锁定或节流到新的输出值。

几种型号的顶部隔膜总成中装有一个安全泄放阀。如果调节压力比设定压力增加3 tnúpsig，并且通过顶部外壳中的大气通风口排出空气，则其工作。超压导致隔膜向上移动，从而打开安全泄放阀。

Air Loading

Provision for supplementary air loading (100 psig max) in

addition to spring loading

Model 40, 42: 1/4" NPT

Model 41: 1/8" NPT

Model 40-2: Not available

Add [A] into the model number.

Example: 40A15

Tapped Exhaust

Provision for piping exhaust flow away from the regulator

Model 40, 42: 1/8" NPT

Model 41: Not available

Add [E] into the model number.

Example: 40E15

Isothermal Range Spring

Reduces ambient temperature effect from approximately

1% of set pressure to approximately 0.1% for a 50°F

[27°C] temperature range

Model 40: 15, 30, 50, & 100 psig ranges

Model 41: Not available

Model 42: 30, 50, & 100 psig ranges

Add (M9) to the Moore 40 number.

Add (M26) to the Moore 42 model number.

Example: 40-15M9, 42-30M26

Deletion of Safety Release Valve (SRV)

The SRV increases exhaust flow capacity when the

regulator must exhaust large flows. Deletion of the SRV will

improve drift characteristics (see Graph 4). The SRV is not

available with the Moore 41. It is standard with:

Model 40: 2, 7, 15, 30, 50 & H50 pressure ranges

Model 42: 15, 30, 50, H30, & H50 pressure ranges

To delete the SRV, add an [X] into the model number.

Example: 40X15

Slotted Adjusting Screw

Available for all models. This option provides for screwdriver

adjustment of the regulator and includes a locknut.

Model 40: Add (M3) after the model number

Model 41: Add (M3) after the model number

Model 41: Add (M20) after the model number

Example: 40-15(M3)

Locknut with Longer Adjusting Screw

Available for all models. This option prevents inadvertent

regulator adjustment.

Model 40: Add (M13) after the model number.

(Note: The Model 40-2 is standard with the lock nut.)

Model 41: Add (M5) after the model number or order

accessory P/N 3603-22.

Model 42: Add (M3) after the model number

Example: 40-15(M3)
