Description and Application
Product details
1.DEVEC/DEVECH Isolating explosion type solenoid valves (short as explosion proof valves) are widely used at gas transmission and control to provide opens and shuts or emergency shut-off for pipe line.
2.Its explosion proof performance meets the regulations of GB*5.3.*****0 and GB***6.*****0, granting the sign Exdâ…¡B T4 Gb. It can be used at danger zone 1 and 2 of a working area with â…¡B sign, using explosive gas within the range of T1 to T4 (**0VAC *0Hz).
3.It adopted a modular design allowing it to save installation space, easier to be maintained (no need to disassemble the pipe line) comparing to common valves.
4.It can be applied to gas medium, such as natural gas, methane, LPG and so on.
Operation and installation:Normally closed type, after the power is energized, it will open quickly, and when the power is off, it will be shut down immediately.There are bypass holes on both sides of the valve body, and the hole diameter is G1/4"
