TLV COS Series User Manual

Introduction
Steam-using equipment can perform its intended operation only when dry saturated steam is
available. Steam containing entrained condensate, scale, air, etc. not only reduces steam
equipment productivity, but also shortens the life of pressure reducing valves.
REDUCING VALVES models COS/COSR are innovative reducing valves, which help
eliminate these problems by supplying dry saturated steam at a constant pressure at all times.
This manual should be read prior to installing or operating COS/COSR SERIES REDUCING
VALVES.
