Direct-acting solenoid valve ICO4S

3/2-wayNONC

Overview
The ICO4S is an explosion-proof solenoid poppet valve designed for high-pressure hydraulic and pneumatic applications. Suited for air, neutral gases and low-pressure hydraulic media, it provides high flow, low leakage and multiple port/configuration options.

Details
The ICO4S (and ICO4S-HYD for hydraulic variants) are direct-acting solenoid poppet valves built for harsh environments and safety-critical systems. Available in pneumatic and hydraulic versions, they offer SIL 3 capability, zero-leakage sealing and broad environmental protection. Constructed in 316L stainless steel, the series withstands hydraulic service up to 414 bar and pneumatic service up to 20 bar. Certifications include ATEX, IECEx, FM and CSA, making the valves suitable for offshore, oil & gas, power generation and heavy industrial installations.
