Description
ERA SIB 20033 Stainless Steel Solenoid Valve – 1/8" & 1/4" BSP, 0-100 Bar
The ERA SIB 20033 is a compact high-pressure stainless steel solenoid valve designed for reliable control of air, water, gases, vacuum and light oils. Featuring a direct acting operating principle, the valve can operate from zero pressure differential, making it ideal for vacuum systems, pressure vessels, test rigs and demanding industrial process applications.
Available with 1/8" or 1/4" BSPP threaded ports and pressure ratings up to 100 Bar, the ERA 20033 combines robust stainless steel construction with a wide range of sealing materials, coil options and specialist configurations including ATEX, oxygen-cleaned and manual override versions.
Valve Function & Operation
Function: 2/2 way normally closed
Operation: Direct acting
Port Sizes: 1/8" or 1/4" BSPP
Optional Threads: NPT
Pressure Range: Vacuum to 100 Bar
Mounting Position: Any orientation
Opening / Closing Time: 20 mSec maximum
Unlike pressure-assisted valves, the direct acting design enables operation from 0 Bar differential pressure, making the valve suitable for vacuum and low-pressure systems as well as high-pressure applications.
Flow & Orifice Options
Available with multiple orifice sizes to suit different flow requirements:
Orifice Flow Rate*
1.2mm 0.7 L/min
1.6mm 1.4 L/min
2.0mm 2.0 L/min
2.4mm 2.8 L/min
3.0mm 4.0 L/min
4.0mm 5.5 L/min
5.0mm 7.2 L/min
*Based on water with 1 Bar pressure drop.
