200 Bar High Pressure Stainless Steel Solenoid Valve – ERA-SIB 206252–206257
The ERA-SIB 206252–206257 Series is a heavy-duty 2/2 way normally closed high-pressure stainless steel solenoid valve designed for reliable control of air, water, light oils and compatible gases at operating pressures up to 200 Bar.
Unlike a direct-acting high-pressure valve, this range uses a pressure-assisted servo design with a 1 Bar minimum pressure differential, allowing a substantially larger 6mm flow orifice while maintaining high-pressure capability. This makes the series particularly suitable where both high working pressure and useful flow capacity are required.
Manufactured with an AISI 316L stainless steel body and stainless steel internal components, the range offers excellent corrosion resistance for demanding industrial and process applications. NBR seals are standard, with EPDM, FKM / Viton® and PTFE options available to suit different media and operating conditions.
Valve Function & Operation
Function: 2/2 way normally closed
Operation: Pressure assisted / servo operated
The valve remains closed when electrically de-energised and opens when power is applied to the solenoid.
The pressure-assisted design uses system pressure to assist operation of the main valve mechanism. This allows the ERA-SIB 206252–206257 Series to combine high working pressures with a relatively large 6mm flow orifice.
A minimum pressure differential of 1 Bar is required for correct operation.
This range should therefore not be confused with the smaller-orifice direct-acting high-pressure valves that can operate from zero differential pressure.
Ports & Connections
Port sizes:
1/8" BSP
1/4" BSP
Optional connection:
NPT thread
Orifice: 6mm
Water flow: 5 L/min at 1 Bar pressure difference
The 5 L/min figure is based on water with a 1 Bar pressure drop and is therefore stated as a water flow figure rather than conventional Kv in m³/h.
Pressure & Performance
Available operating pressure ranges:
1 to 50 Bar
1 to 200 Bar
Minimum operating differential: 1 Bar
Maximum pressure: 200 Bar
Orifice: 6mm
Opening time: 100ms maximum
Closing time: 100ms maximum
Maximum media viscosity: 40 cSt
The combination of a 6mm orifice and pressure capability up to 200 Bar makes this series particularly useful where a direct-acting valve with a very small high-pressure orifice would provide insufficient flow.
Construction & Materials
Body: AISI 316L stainless steel
Internal components: Stainless steel
Standard seals: NBR
Optional seals:
EPDM
FKM / Viton®
PTFE
The stainless steel construction provides excellent corrosion resistance and mechanical strength for demanding high-pressure industrial applications.
Seal & Media Compatibility
NBR is supplied as the standard sealing material, with alternative seal compounds available to suit different media and temperature requirements.
NBR: General-purpose air, water and compatible light oils
EPDM: Water and compatible aqueous media
FKM / Viton®: Oils, fuels and compatible process fluids
PTFE: Specialist chemical and process applications where compatible
Media suitability should always be confirmed against the 316L stainless steel construction and selected seal material before ordering.
Suitable Media
Depending upon the selected seal configuration, applications can include:
✓ Compressed Air
✓ Water
✓ Light Oils
✓ Compatible Gases
✓ Industrial Process Fluids
Maximum viscosity: 40 cSt
For aggressive chemicals or specialist gases, compatibility should be confirmed before use rather than relying on stainless steel construction alone.
Temperature Range
Maximum media temperatures:
NBR: +60°C
EPDM: +100°C
FKM / Viton®: +100°C
PTFE: +100°C
Ambient temperature: -10°C to +50°C
The actual operating temperature limit is determined by the selected sealing material, media and electrical configuration.
Installation & Mounting
Recommended mounting position:
Vertical with the solenoid coil uppermost
Correct mounting helps ensure reliable operation of the pressure-assisted internal mechanism.
Because this is a servo-operated valve, the required 1 Bar minimum pressure differential must be maintained across the valve for reliable switching.
Coil & Electrical
Standard coil power:
DC: 14–20W
AC: 48VA inrush / 24VA holding
Insulation: Class F 155°C
Duty cycle: 100% ED continuous duty
Protection: IP65 with connector fitted
Electrical connection: DIN 43650A
Construction: Moulded resin encapsulated coil
The industrial solenoid operator is designed for continuous-duty applications and is supplied with a DIN electrical connector for straightforward installation and maintenance.
Voltage Options
DC:
✓ 12VDC
✓ 24VDC
✓ 48VDC
AC 50/60Hz:
✓ 24VAC
✓ 48VAC
✓ 110VAC
✓ 230VAC
Alternative voltage configurations may be available for OEM or specialist applications.
ATEX Hazardous Area Option
An optional ATEX explosion-protected solenoid operator is available for hazardous-area installations.
ATEX classification:
II 2 G/D
Protection:
Ex d IIC T6
The ATEX configuration is intended for installations where explosive gas or dust atmospheres may be present.
The complete valve and operator configuration should be selected according to the required hazardous-area classification, media, operating pressure and ambient conditions.
High-Flow 200 Bar Design
The main advantage of the ERA-SIB 206252–206257 Series is its combination of high working pressure and a comparatively large 6mm flow orifice.
Direct-acting solenoid valves operating at 200 Bar typically require a very small orifice because the solenoid must overcome the entire hydraulic force acting against the valve seat.
By using a pressure-assisted servo design, the 206252–206257 Series can provide a larger flow path while still operating at pressures up to 200 Bar.
For applications where a minimum differential pressure of 1 Bar is continuously available, this can provide a useful alternative to a small-orifice direct-acting high-pressure valve.

Individually Tested Valves
Every valve is individually tested before dispatch, providing additional confidence for demanding high-pressure installations.
Correct pressure range, seal material, voltage and port configuration should be selected according to the application.
Why Choose the ERA-SIB 206252–206257?
The ERA-SIB 206252–206257 provides an effective solution where engineers require high-pressure capability without the extremely restricted flow associated with small-orifice direct-acting valves.
Its pressure-assisted construction provides a 6mm orifice with working pressures up to 200 Bar, while the AISI 316L stainless steel body provides excellent durability and corrosion resistance.
Multiple seal options, AC and DC voltages, optional NPT connections and an ATEX Ex d configuration make the range suitable for a wide variety of industrial, OEM and process-control installations.
