For over 50 years, IMI Herion has specialised in solenoid valves and associated equipment for both pneumatic and hydraulic applications: comprehensive ranges of solenoid valves, NAMUR valves, pressure switches and press safety valves, ideally suited to aggressive and harsh environments — with global approvals including ATEX and SIL.
Created specifically for the chemical and process industries: high functionality, energy-saving modular solenoid systems and compact designs, resilient in hazardous environments — with certifications including SIL, ATEX, IECEx, TR-CU, CSA, CCOE, FM, Inmetro and ITRI.
Herion solenoid valves offer a Force Friction Ratio of 10 — together with Maxseal, the highest in the industry — meaning the valve is highly likely to operate when demanded, even at extreme temperatures.
Press safety valves and NAMUR interface valves complement the range, alongside pneumatic and hydraulic pressure switches — for machine safety and process interfaces.
3/2-way pilot-actuated poppet valve — port sizes from 1/2" to 1 1/2" (ISO G or NPT), orifice sizes from 15 to 40 mm.
3/2, 5/2 and 5/3 solenoid-operated spool valves in inline and NAMUR configurations.
3/2 direct solenoid actuated poppet valve — G1/4, 1/4 NPT and NAMUR ports, 0-10 bar, -40 °C to +120 °C.
Direct solenoid-actuated 3/2 poppet valve with a mechanical return spring for a fail-safe position — G1/4 or 1/4 NPT.
Indirect solenoid actuated spool valve with 3/2 or 5/2-way function — G1/4 or 1/4 NPT port size.
3/2 direct solenoid actuated poppet valve — 0 to 10 bar pressure range with an 8 mm orifice.
FFR measures the relationship between the spring-return force and the frictional resistance within the valve — the higher it is, the more reliably the valve operates when demanded. Herion valves offer an FFR of 10, the highest in the industry alongside Maxseal.
Global certifications including SIL, ATEX, IECEx, TR-CU, CSA, CCOE, FM, Inmetro and ITRI — making the range suitable for hazardous areas and safety-critical process applications.
