      Pressure Reducing Valves Direct Acting for steam RE1

      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

        Control bellows with moren than ... operating cycles offers outstanding durability. Protected by integrated strainer.

      • Easy handling

        Pressure can easily adjusted by the topside handle.

      Typical applications

      Perfect for small to medium steam flows as present in laundries, F&B equipment, sterilizers and similar equipment.

      ● How to use this chart

      1. Find the point at which the upstream pressure and desired downstream pressure horizontal line intersect.

      2. Trace a vertical line from the point where they intersect, and select for the smallest-nominal size where the required steam flow rate met.

      *for downstream pressures from 0,4MPa (58psig) (4kgf/cm2・g) to 0,2MPa (29psig) (2kgf/cm2・g) or lower, use RE1-4 model.

        for downstream pressures from 0,2MPa (29psig) (2kgf/cm2・g) or lower with high flow rate, RE1-2 is recommended.
