Piston valve COS series

hydraulically-operatedpressure-reducingfor steam

COSPECT®’s built-in strainer, Super Cyclonical Effects Separator (SCE) and Free Float® steam trap help prevent scale, rust and condensate from entering the pressure reducing valve (PRV) or reaching the important interior parts. In particular, the cyclone separator forcibly removes 98% of the condensate from the flow at the inlet side, thereby greatly reducing condensate-induced erosion of parts such as the main valve. While the standard service life of a PRV for steam is often less than a few years, many TLV COSPECT® users are still using their COSPECT® PRVs more than 10 years after installation. Such long service life is a testimony to COSPECT®'s effectiveness in countering scale and condensate, some of the most common sources of problems for PRVs in steam systems. Benefits and Features Improved Quality of Material Being Heated Delivers Stable Pressure Achieves secondary pressure accuracy within ±0.01 MPa of the set level. Even if the steam flow (load) to the equipment or the primary pressure at the pressure reducing valve changes, the Shock-Absorbing Spherical Piston (SAS) supplies steam at a constant pressure in order to prevent temperature fluctuation downstream. Supplies Dry Steam The built-in Cyclone Separator removes condensate from steam with a condensate separation efficiency of 98%. Condensate entrained in the steam is removed, and a strainer further removes any scale. The condensate that is separated out is discharged through the built-in Free Float® steam trap. The increased quality of the steam contributes to improved heat conductivity.
