ICO4S - Hydraulic Solenoid Valve
Direct-acting solenoid valve for hydraulic control with zero leakage and high pressure capability.
Provides reliable, zero-leakage hydraulic control up to 414 bar with a direct-acting poppet design.
Certified for high safety integrity levels and hazardous area use, ensuring suitability for critical systems.
Offers installation flexibility with multiple port types, mounting options, and voltage configurations.
Features
The ICO4S is a compact, direct-acting hydraulic solenoid valve designed for precise and reliable control of hydraulic equipment. Available in 2/2 or 3/2 configurations, it operates at pressures up to 414 bar and is suitable for zero-leakage applications. The valve is constructed from stainless steel with high-grade seals and can be mounted in vertical solenoid orientation. It features options for manual reset, manifold mounting, and various electrical connections. Certified to SIL 3 and SIL 4 (redundant), and approved for hazardous areas (ATEX, IECEx, CSA), the ICO4S is ideal for critical safety and control applications across harsh environments.
