    Benefits and Features

    Improved Quality of Material Being Heated

    Accuracy of pressure reducing valve's secondary set pressure is within ± 0.01 MPa.

    Even if the steam flow (load) to the equipment or the primary pressure at the reducing valve changes, the Shock-absorbing Spherical piston (SAS) supplies steam at a constant pressure in order to maintain the temperature of the steam used as the heating source.

    Easy to Adjust

    Pressure adjustment is simple and can be done by using 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

    • Steam supply lines, steam heating equipment, heaters, etc.
