The GF 3-2751-3 is a direct-acting solenoid valve engineered for precise on/off control of aggressive fluids in industrial automation. Featuring a PBT (polybutylene terephthalate) body with EPDM seals, it delivers uncompromising chemical resistance against acids, bases, and solvents while maintaining dielectric isolation for electrical safety. The "3" suffix designates its 24V DC coil with IP65-rated connector (IEC 60529) and manual override lever. Designed for DN8 (¼") systems, the valve employs a PTFE-free plunger system with balanced pressure design to operate at 0 bar differential. Certified to ISO 13845 SIL CL1 and ATEX/IECEx Zone 2 standards, it handles temperatures from -10°C to +90°C, making it ideal for chemical dosing, analytical instrumentation, and hygienic processes without brass contamination risks.

Optimized for corrosive media control:

• Pressure Range: 0 to 10 bar (145 psi) | Vacuum capability: -0.95 bar
• Media Temperature: -10°C to +90°C (EPDM seals) | Ambient: -20°C to +60°C
• Voltage: 24V DC ±10% (1.8W power consumption)
• Response Time: <20ms open/close (1 bar ΔP)
• Flow Coefficient (Kv): 0.4 m³/h | Cv: 0.18
• Leakage: Class IV (DIN EN 12266-1)
• Body Material: UL94 V-0 PBT (halogen-free)
• Seals: FDA-compliant EPDM (FKM optional)
• Port Connection: G¼" BSPP female threads
• Electrical Protection: Coil Class F (155°C) with surge suppression
• Certifications: RoHS, REACH, ATEX II 3G Ex ec IIC T4 Gc

Critical fluid management in corrosive environments:

• Chemical Dosing: HCl/NaOH metering pumps in water treatment
• Laboratory Automation: Analyzer reagent control (ISO 15848-1 compliance)
• Pharmaceutical: Buffer solution distribution in bioprocess skids
• Food Processing: CIP chemical injection with steam sanitation
• Semiconductor: UPW distribution valve manifolds
• Analytical Instruments: GC/MS carrier gas shutoff systems

Compatible with media including glycols, ozone water, and 30% sulfuric acid. Excludes viscous fluids (>15 cSt) and particulates.

Superior reliability in demanding installations:

• Zero Metallic Contact: All-wetted parts chemically inert (PBT + EPDM)
• Energy Efficiency: Low-power coil (40% less vs. AC designs)
• Dry Operation Capability: Balanced core design eliminates minimum ΔP requirement
• Chemical Immunity: 4000+ chemical compatibility per GF resistance guide
• Fail-Safe Versatility: Optional NC/NO configurations
• EMC Protection: Built-in varistor withstands 2.5kV transients

Features GF's SmartTag® NFC for mobile commissioning - scan coil label for installation documents and maintenance history.

Advanced process integration features:

• Manual Override: Tactile lever for emergency operation without power
• Low Noise: 45 dB(A) silent operation (EN 12102 standard)
• Pulse Frequency Tolerance: 100 Hz modulation capability for proportional control
• Thermal Protection: PTC sensor prevents coil burnout
• Mounting Flexibility: Omni-directional installation (±15° from vertical)
• Fail-Safe Options: Springs certified for 500,000 cycles

Supports IO-Link communication (Version 1.1.3) for predictive maintenance data and cloud integration.
