Description
ERA SIB WFH Normally Open Stainless Steel Solenoid Valve – Up to 300 Bar
The ERA SIB WFH is a high-pressure normally open stainless steel solenoid valve designed for demanding industrial, gas control, hydraulic, process and automation applications. Featuring a direct acting operating principle, the valve remains open when de-energised and closes when power is applied, making it ideal for fail-safe systems where flow must be maintained during power loss.
With pressure ratings up to 300 Bar, stainless steel construction and multiple seal options, the WFH series provides reliable control of air, water, gases, light oils and industrial fluids in challenging operating environments.
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: 0 to 300 Bar
Mounting Position: Any orientation
Unlike pressure-assisted valves, the direct acting design allows operation from zero pressure differential and vacuum through to maximum working pressure.
Flow & Orifice Options
Available with multiple orifice sizes:
Orifice Kv Flow Factor
0.5mm 0.15 L/min
0.8mm 0.35 L/min
1.0mm 0.55 L/min
1.5mm 1.10 L/min
2.5mm 2.30 L/min
Flow based on water with 1 Bar pressure drop.
The range of orifice options allows the valve to be optimised for both high-pressure shut-off and flow performance.
