Description
1/8" & 1/4" 300 Bar Brass Solenoid Valve – EN52000 Series
ERA-SIB EN52000 Series high pressure 2/2 way normally closed brass solenoid valve designed for CO₂, nitrogen and Inergen fire suppression systems.
This compact direct acting solenoid valve operates from 0 to 300 Bar without requiring a minimum pressure differential, making it particularly suitable for high-pressure gas control and fire suppression applications.
Available with 1/8" or 1/4" BSP ports, the EN52000 Series features a brass valve body, stainless steel internal components and PTFE + EPDM seals as standard. Manual override and ATEX EEx d IIC T6 explosion-proof versions are also available.
With a fast opening or closing time of 30 milliseconds maximum, the valve is designed for rapid actuation in high-pressure gas discharge and control systems.
Function & Operation
Function: 2/2 way normally closed
Operation: Direct acting
Pressure range: 0 to 300 Bar
Minimum differential pressure: 0 Bar
The direct acting design allows the valve to operate from zero pressure differential while retaining a maximum working pressure of 300 Bar. This makes the EN52000 Series particularly suitable for high-pressure gas applications where reliable shut-off and rapid electrical operation are required.
The manufacturer's datasheet specifies a maximum opening or closing time of 30 milliseconds. media_2828
