Stainless steel solenoid valves

Stainless steel solenoid valves are engineered for precision fluid control across a wide range of industrial applications. Whether you're working with air, water, oils, fuels, or inert gases, these valves offer corrosion resistance, durability, and reliable performance under harsh operating conditions. Constructed with 304 or 316 CF8M stainless steel bodies and high-grade stainless steel internals, they ensure long service life and compatibility with demanding media.

Key Features of Stainless Steel Solenoid Valves

Premium Materials for Long-Term Reliability

Body: 304 or 316 CF8M stainless steel for superior corrosion resistance

Internal Components:

Armature: Magnetic 430F stainless steel

Armature Tube: 304 stainless steel

Armature Spring: 302 stainless steel

Seals & Elastomers: Choose from NBR, EPDM, Viton, HNBR, or PTFE depending on chemical compatibility and temperature requirements

Wide Media Compatibility

These valves are suitable for:

Compressed air and inert gases

Cold and hot water

Light and heavy oils

Fuels including diesel and petrol

Corrosive or hazardous fluids (when paired with appropriate seals)

Solenoid Valve Operation Explained

Zero Rated Solenoid Valves (Direct Acting)

Zero-rated valves operate from vacuum conditions up to the valve’s maximum working pressure. They are ideal for low or no-pressure systems and are also known as:

Direct acting solenoid valves

Kick pilot valves

Assisted lift or hung diaphragm valves

Pilot Assisted Solenoid Valves

These valves rely on a pressure differential between the inlet and outlet (typically 0.5 Bar or 7 PSI minimum) to function. Also known as:

Floating diaphragm valves

Servo-assisted valves

Internal pilot-operated solenoid valves

Solenoid Valve Functions and Flow Configurations

2/2 Way Solenoid Valves (Two-Port)

Normally Closed (NC)

Zero Rated: Valve is closed when de-energised; opens when powered

Pressure Assisted: Requires inlet pressure ≥0.5 Bar more than outlet; valve opens only when energised

Normally Open (NO)

Zero Rated: Valve remains open when de-energised; closes upon powering

Pressure Assisted: Requires pressure differential to close valve when powered

Latching Solenoid Valves

These valves maintain position with a power pulse—one polarity to open, the reverse to close—making them ideal for battery-powered or energy-saving systems.

Multi-Port Solenoid Valves

3/2 way and 5/2 way valves: Feature three or five ports for directional control in pneumatic systems, ideal for actuator and cylinder applications.

ATEX Certified Stainless Steel Solenoid Valves

When working in hazardous environments, ATEX approved solenoid valves are essential. Available in 2/2, 3/2, or 5/2 configurations, these valves are designed for explosive atmospheres involving gas or dust. Safety protection levels include:

ATEX EExmIIT4 (Encapsulation)

ATEX EExdIICT6 (Flameproof Enclosure)

ATEX EEXiaIICT6 (Intrinsically Safe)

These valves provide enhanced protection for offshore platforms, chemical plants, mining sites, and other explosion-risk industries.
