Siemens 40-2精密減壓閥Series 40特點(diǎn)和優(yōu)點(diǎn)：

◆多級低下垂精密調(diào)節(jié)器在流量和供給壓力的大范圍變化中保持恒定輸出

◆環(huán)氧粉末涂料提高了耐腐蝕性

◆調(diào)節(jié)壓力[1“到450 psi]的廣泛選擇提供了應(yīng)用的多功能性

◆零壓力調(diào)節(jié)系統(tǒng)提供可靠的免維護(hù)操作

Siemens 40-2精密減壓閥Series 40產(chǎn)品說明：

Series 40、Series 41和Series 42型精密壓力調(diào)節(jié)器控制需要精確可靠調(diào)節(jié)的應(yīng)用中的空氣壓力，例如氣動儀表回路、試驗(yàn)臺、生產(chǎn)檢查夾具和工業(yè)空氣表。因此，它們適合于死胡同服務(wù)，流量可達(dá)110 scfm。

一個(gè)*的，兩階段試點(diǎn)設(shè)計(jì)提供了的準(zhǔn)確性。堅(jiān)固的結(jié)構(gòu)，沒有連桿、杠桿、樞軸或其他產(chǎn)生摩擦的構(gòu)件，確?？煽?、免維護(hù)操作。這些特性使調(diào)節(jié)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(shí)上，使用型號40、41或42的調(diào)節(jié)器實(shí)際上是一個(gè)獨(dú)立的壓力控制器，通過一個(gè)內(nèi)置的高增益氣動放大器來操作其供應(yīng)柱塞閥。

一個(gè)精細(xì)轉(zhuǎn)動的精密螺釘用于手動加載量程彈簧，該彈簧可設(shè)置調(diào)節(jié)壓力。當(dāng)順時(shí)針轉(zhuǎn)動調(diào)節(jié)旋鈕時(shí)，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(dǎo)壓力。因?yàn)橄葘?dǎo)壓力的來源是通過節(jié)流閥流向先導(dǎo)壓力室的供氣螺釘，升高的先導(dǎo)壓力迫使排氣隔膜總成向下。此動作關(guān)閉排氣口，接觸并移動閥柱塞，從而打開供油口。這增加了調(diào)節(jié)輸出，也反饋到頂部隔膜組件。當(dāng)頂部隔膜組件的反饋力等于范圍彈簧力時(shí)，調(diào)節(jié)器鎖定或節(jié)流到新的輸出值。

幾種型號的頂部隔膜總成中裝有一個(gè)安全泄放閥。如果調(diào)節(jié)壓力比設(shè)定壓力增加3 tnúpsig，并且通過頂部外殼中的大氣通風(fēng)口排出空氣，則其工作。超壓導(dǎo)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.
