Built from the same basis of design principles as the Mark One but fabricated from bar stock, the Mark Two is an extremely versatile control valve. Due to its constructions, it is available in many different configurations with shorter lead times than conventionally cast valve bodies, even in high-pressure classes or special alloys.
