The L08 is a compact, spring-loaded pressure maintaining valve from the IMI Thompson Valves product range. Designed for accurate control of inlet pressure in gas systems, it maintains a set upstream pressure through manual adjustment. With a 5 mm seat and tamperproof design, it delivers reliable performance in compressor discharge, filter systems, dryers, and overpressure control. It supports inlet pressures up to 420 barg and control ranges from 10 to 400 barg, with bubble-tight shut-off as standard. Available in stainless steel or aluminium, it suits low, medium, and high-pressure applications across industrial gas systems.
