Description

1/8"–3/8" Stainless Steel Normally Open Steam Solenoid Valve

The Di-Hen NOSUS610 Series is a high-temperature 2/2 way normally open stainless steel solenoid valve designed for automatic control of steam, hot water, air, vacuum, light oils and other compatible fluids. Featuring a corrosion-resistant 316 stainless steel body, direct acting operation and high-temperature sealing options, the NOSUS610 provides dependable flow control in industrial steam and process applications.

Available in 1/8", 1/4" and 3/8" BSP female threaded connections, this normally open solenoid valve remains open when electrical power is removed and closes when the solenoid coil is energised.

Its direct acting design requires no minimum pressure differential, allowing operation from zero pressure through to the maximum rating of the selected port size and voltage configuration.

With media temperatures up to +185°C for suitable seal configurations, the NOSUS610 is an effective solution for industrial steam equipment, heating systems, hot water processes and applications requiring a normally open valve arrangement.

Normally Open Operation

The NOSUS610 is a 2/2 way normally open direct acting solenoid valve.

Power OFF → Valve Open

Power ON → Valve Closed

When the coil is de-energised, the valve remains in its normally open position, allowing fluid to pass through.

Applying electrical power energises the solenoid and moves the internal armature to close the valve.

This arrangement is suitable for applications where the valve must return to its open position following electrical power loss.

Because the valve is direct acting, no minimum operating pressure or pilot pressure is required.

Port Sizes, Orifices & Flow

The NOSUS610 Series is available in three BSP female threaded sizes:

1/8" BSP – NOSUS6

Orifice: 2.5mm
Flow Coefficient: 0.23m³/h
Pressure Range AC: 0–7 bar
Pressure Range DC: 0–5 bar

1/4" BSP – NOSUS8

Orifice: 2.5mm
Flow Coefficient: 0.23m³/h
Pressure Range AC: 0–7 bar
Pressure Range DC: 0–5 bar

3/8" BSP – NOSUS10

Orifice: 4.0mm
Flow Coefficient: 0.58m³/h
Pressure Range AC: 0–10 bar
Pressure Range DC: 0–7 bar

Optional NPT and BSPT threaded connections are available.

The correct pressure rating must be selected according to the valve size and coil voltage.

316 Stainless Steel Construction

The NOSUS610 features a robust CF8M (316) stainless steel body, offering corrosion resistance for suitable industrial steam and fluid control applications.

Construction materials:

Valve Body: 316 stainless steel (CF8M)
Core Tube: Stainless steel
Internal Components: Stainless steel
Standard Seals: FKM (Viton) with PTFE O-ring
Optional Seals: Silicone or NBR
Washer: PTFE or NBR
Coil Encapsulation: Moulded resin

The stainless steel construction provides a durable alternative to conventional brass steam solenoid valves where improved corrosion resistance is required.

Steam Temperature & Media Compatibility

The NOSUS610 Series is designed for compatible industrial fluids, including:

Steam
Hot water
Air
Vacuum
Light oils
Compatible gases

Operating conditions:

Maximum Media Temperature: +185°C, subject to the selected seal and valve configuration
Ambient Temperature: -5°C to +60°C
Maximum Media Viscosity: 50 cSt
Opening/Closing Time: 20 milliseconds maximum

Solenoid Coil & Electrical Options

The NOSUS610 is available with several electrical supply options:

12V DC
24V DC
110V AC, 50/60Hz
230V AC, 50/60Hz

Standard coils feature flying-lead electrical connections.

Electrical protection:

Standard Coil: IP54
Optional M Coil: IP65 with DIN 43650 Form A connector

The appropriate electrical configuration depends on the selected valve size and coil option.

Installation & Maintenance

The NOSUS610 should be installed with the solenoid coil in the upright position, as specified by the manufacturer.

Before installation, verify the valve's port size, operating pressure, coil voltage, seal compatibility and media temperature.

Replacement coils and armature assemblies are available to support servicing and maintenance of compatible valve assemblies.
