Profile: Thompson Valves Ltd. specializes in providing valves and control products. We can supply to the nuclear, oil & gas, petrochemical, and marine markets. We can overhaul and service any IVP product, from a single stand alone product, to a much more bespoke intricate special unit such as a 2 stage pressure reduction station manifold. Our maxseal valves utilize very high-force return springs as standard, ensuring that they operate when required. This feature is coupled with market-leading coil technology which guards against safe failures/spurious trips. The famous 1/4" & 1/2" stainless steel, 3-port, direct-acting ICO4S solenoid valve for instrument changeover duties offers the offshore and petrochemical industries uniquely reliable and heavy-duty unit. The range also includes 2 and 5-port configurations, as well as the ICO4N variant for specific applications.
