GEMÜ 8258

The GEMÜ 8258 servo assisted 2/2-way solenoid valve provides flow isolation for inert gaseous and liquid media. The GEMÜ 8258 accommodates nominal sizes from DN 8 to DN 50, regulates operating pressures between 0.1 and 16 bar, and withstands media temperatures ranging from -10°C to 110°C. Key Performance Capabilities: Rapid Maintenance Integration: The GEMÜ 8258 features a tool free Click-on coil replacement system, reducing maintenance duration and preventing unplanned downtime during electrical component servicing. System Shock Prevention: The GEMÜ 8258 executes a soft closing action, preventing water hammer effects to protect downstream pipework integrity and reduce long term pipeline repair costs. Low-Differential Actuation: The GEMÜ 8258 requires a minimum pressure differential of only 0.1 bar for operation in closed systems, ensuring reliable flow regulation without the need to install expensive high pressure booster pumps. Safety & Compliance: Explosive Environment Security: The GEMÜ 8258 offers optional explosion protected solenoids conforming to ATEX standards, preventing electrostatic ignition risks to guarantee facility safety within volatile industrial zones. Potable Water Certification: The GEMÜ 8258 configured with EPDM seals holds KTW approval for nominal sizes up to DN 25, ensuring plant engineers can safely integrate the unit into drinking water networks. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific diaphragm material and selected connection standard for the GEMÜ 8258.
