    Designed for small, but critical power applications

    ASME 600 / 900/ 1500 Limited Class: Small in Size – Large in Performance

    In power generation systems there are several severe service applications that require a small bore and/or light weight drain, vent or isolation valve. Many of the standard commodity choices such as globes cannot handle absolute tight shutoff for these small bore, high pressure, and high temperature installations, and normal metal-seated ball valves weigh too much. MOGAS offers a real workhorse for the small, but critical applications.
