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.
