Explosion proof Solenoid Valve

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 GB35.3.1-2010 and GB3836.2-2010, granting the sign ExdⅡB T4 Gb. It can be used at danger zone 1 and 2 of a working area with ⅡB sign, using explosive gas within the range of T1 to T4 (230VAC 50Hz).

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.
