    Pressure Reducing Valves Direct Acting for steam REC1

    Features/Applications

    Features

    • Self acting pressure reducing valve for steam

      Automatic valve that reduces the steam supply pressure to a defined set pressure.
      Pressure fluctuations on upstream side are followed by the downstream side.
      No external energy required

    • Operating features of direct acting pressure reducing valves

      Downstream pressure changes are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to maintain the set pressure.

    • Compact and cost effective design

      Can be installed in tight spaces thanks to its compact design (small/lightweight). Offers reliable operation, energy saving, and productivity improvement.

    • Superb durability

      Most of materials are made from stainless steel, making it durable and corrosion-resistant.

    • Easy handling

      Pressure can easily adjusted by the topside handle.

    Typical applications

    Suitable for F&B equipment, medical equipment, bio-related equipment, and other compact steam equipments.

    ● Minimum differential pressure is 10% of the primary side
    ● Minimum adjustable flow rate is 3 to 30kg/h (6.6 to 66 lb/h)
    ● Lockup pressure Up to 0,03MPa (4.4psig)

    ● Offset pressure
         Up to 60% of the secondary side when secondary side pressure is 0,1MPa (14.5psig) or lower
      Up to 0,07MPa (10.2psig) when secondary side pressure exceeds 0,1MPa (14.5psig) but is less than 0,6MPa (87psig)
      Up to 0,1MPa (14.5psig) when secondary side pressure is 0,6MPa (87psig)

    ● How to use selection chart (example)
    To reduce the pressure of 100kg/h (220lb/h) of steam from 1,0MPa to 0,5MPa (145psig to 73psig)

     

    1. Find the point at which the primary side pressure 1,0MPa (145psig) curve and secondary side pressure 0,5MPa (73psig) horizontal line intersect.

     

    2. Trace a vertical line from the point where they intersect, and look for the smallest-sized product where the steam flow rate is 100kg/h (220lb/h) or more at the point where the vertical line you have traced intersects the horizontal size lines.

     

    3. In this case, the REC1-6(F) pressure reducing valve with a size of 15A (1/2”) is optimum.
