    Pressure Reducing Valves With Pulse line for steam　REC20L

    Features/Applications

    Features

    • Pressure reducing valves for steam

      These are automatic valves that reduce the steam supply pressure to the certified pressure for the device in use, and keep it steady.

    • Operating features of direct acting pressure reducing valves

      Pressure changes on the secondary side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the secondary side at a set level.

    • Made completely of stainless steel

    • Due to carefully selected springs a wide range of pressure applications is available.

    • Maximum pressure reduction ratio 25:1

    • As option the valve can be equipped with a pressure gauge on the valve body.

    Uses

    Perfect for cleaning devices, foodstuff devices, and other forms of compact steam equipment.
