這些閥門具有TüV的IEC 61508功能安全數(shù)據(jù)，較高可以使用SIL-4

?電磁閥TJ用于具有基本流量的先導應用，

寬的壓力范圍和較的操作壓力

?聚四氟乙烯車手環(huán)和石墨填充聚四氟乙烯密封減少摩擦和

消除粘附

?用于金屬外殼的線圈采用H級絕緣材料

?功耗的特殊執(zhí)行

?特別執(zhí)行極的環(huán)境溫度

?峰值電壓抑制二極管在帶有金屬的直流電磁鐵中是標準配置

機箱

?電磁閥符合所有相關(guān)EC指令The valves have TüV certified IEC 61508 Functional Safety data and can be used up to SIL-4

? The solenoid valves are recommended for pilot applications with basic flow,

wide pressure ranges and no minimum operating pressure

? PTFE rider rings and graphite-filled PTFE seals reduce friction and

eliminate sticking

? Coils used in metal enclosures have class H insulation materials

? Special execution for low power

? Special execution for extreme low ambient temperatures

? Peak voltage suppression diodes are standard in DC solenoids with metal

enclosures

? The solenoid valves satisfy all relevant EC Directives

Multi language installation/maintenance instructions are included with each valve

● The solenoid valves can be mounted in any position without affecting operation

● The mounting holes are provided in the valve body

● Threaded pipe connection identifier is 8 = NPT (ANSI 1.20.3); G = G (ISO 228/1)

● Declarations of conformity are available on request

● EEx em (prefix "EM") execution: solenoid enclosure has a cable gland with integral strain relief for cables with an o.d.

from 7 to 12 mm and is pro電磁閥可以安裝在任何位置，不影響操作

●閥體上有安裝孔

●螺紋管連接標識符是8 = NPT（ANSI 1.20.3）; G = G（ISO 228/1）

●合格聲明可根據(jù)要求提供

●EEx em（前綴“EM”）執(zhí)行：螺線管外殼有一個電纜密封套，帶有整體應變消除裝置，用于帶有O.d的電纜。

從7到12毫米，是親

用一個內(nèi)部和外部的連接裝置對接地或連接導體進行檢查

●EEx d（前綴“（WS）NF”）外殼帶有1/2“NPT螺紋入口孔，M20 x 1,5（前綴”ET“）是可選的。

兩者都提供沒有電纜密封套

●所有帶金屬外殼的直流電磁鐵均配有關(guān)斷峰值電壓抑制二極管

vided with an internal and external connection facility for an earthing or bonding conductor

● EEx d (prefix "(WS)NF") enclosure is provided with a 1/2" NPT threaded entry hole, M20 x 1,5 (prefix "ET") is optional.

Both are supplied without cable gland

● All DC solenoids with metal enclosure are provided with switch-off peak voltage suppression diodes

● To comply with IEC 61508 (SIL) the valves must be provided with a specific exhaust protector (as shown on page 5) or equal
