Siemens 40-2精密減壓閥Series 40特點和優點：

◆多級低下垂精密調節器在流量和供給壓力的大范圍變化中保持恒定輸出

◆環氧粉末涂料提高了耐腐蝕性

◆調節壓力[1“到450 psi]的廣泛選擇提供了應用的多功能性

◆零壓力調節系統提供可靠的免維護操作

Siemens 40-2精密減壓閥Series 40產品說明：

Series 40、Series 41和Series 42型精密壓力調節器控制需要精確可靠調節的應用中的空氣壓力，例如氣動儀表回路、試驗臺、生產檢查夾具和工業空氣表。因此，它們適合于死胡同服務，流量可達110 scfm。

一個*的，兩階段試點設計提供了的準確性。堅固的結構，沒有連桿、杠桿、樞軸或其他產生摩擦的構件，確保可靠、免維護操作。這些特性使調節器能夠保持恒定的輸出壓力，不管怎樣即使是流量或供給壓力的變化。事實上，使用型號40、41或42的調節器實際上是一個獨立的壓力控制器，通過一個內置的高增益氣動放大器來操作其供應柱塞閥。

一個精細轉動的精密螺釘用于手動加載量程彈簧，該彈簧可設置調節壓力。當順時針轉動調節旋鈕時，增加的彈簧力施加在頂部隔膜組件上，從而減小噴嘴間隙并增加先導壓力。因為先導壓力的來源是通過節流閥流向先導壓力室的供氣螺釘，升高的先導壓力迫使排氣隔膜總成向下。此動作關閉排氣口，接觸并移動閥柱塞，從而打開供油口。這增加了調節輸出，也反饋到頂部隔膜組件。當頂部隔膜組件的反饋力等于范圍彈簧力時，調節器鎖定或節流到新的輸出值。

幾種型號的頂部隔膜總成中裝有一個安全泄放閥。如果調節壓力比設定壓力增加3 tnúpsig，并且通過頂部外殼中的大氣通風口排出空氣，則其工作。超壓導致隔膜向上移動，從而打開安全泄放閥。

Siemens Series 40精密減壓閥Options：

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)

Bushings for mounting on panels up to 3/4" thick

(Standard maximum is 1/4" thick).

Model 40: Add (M41) after the model number

Model 41: Not available

Model 42: Add (M14) after the model number

Example: 40-15(M41)
