Benefits and Features 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. Easy to Adjust Pressure adjustment is simple; just use the cover cap as the adjustment spanner. Long Service Life Rust presents a high risk to vital areas of the system. To eliminate this, all major valve components are made of stainless steel to prevent rust and corrosion. Additionally, the inclusion of a strainer in the piping installation prevents the inflow of rust and other debris, protecting the valve components and contributing to a long service life. Application Areas Recommended for processes requiring steam at a stable pressure and processes such as atomizers in which steam comes into direct contact with the product. Main Applications Reactor kettles, dryers, heat exchangers, presses, steamers, blowers, atomizers, etc.
