Description
ERA SIB 200201NO Normally Open Brass Solenoid Valve
The ERA SIB 200201NO is a compact direct acting normally open solenoid valve designed for reliable control of air, water, vacuum, light oils and compatible industrial fluids. Operating on a power-to-close principle, the valve remains open when de-energised, making it ideal for fail-safe systems, continuous flow applications and industrial automation processes where flow must continue during power loss.
Manufactured with a robust brass body, stainless steel internals and high-quality sealing materials, the 200201NO provides dependable operation from vacuum up to 20 Bar without requiring a minimum pressure differential.
Valve Function & Operation
Function: 2/2 way normally open
Operation: Direct acting
Fail-Safe Position: Open
Port Sizes:
1/8" BSP
1/4" BSP
Optional Connection: NPT thread
Pressure Range: Vacuum to 20 Bar
Mounting Position: Any orientation
Direct acting operation allows the valve to function from zero pressure, making it suitable for vacuum systems and low-pressure applications.
Flow & Orifice Options
Available with multiple orifice sizes to suit different flow requirements:
Orifice Kv Flow Factor
1.5mm 0.65 – 1.2 L/min
2.0mm 1.0 – 1.5 L/min
2.5mm 1.4 – 2.2 L/min
3.5mm 2.1 – 4.9 L/min
4.5mm 6.2 L/min
Flow based on water with 1 Bar pressure drop.
