    Features/Applications

    Features

    • Compact and cost effective design

      It has a space saving, simple mechanism with very few moving components.

    • Easy maintenance

      The minimum of moving parts and an easy in-line access ensures easy and fast maintenance.

    • Special design against steam locking

      To avoid cases of steam locking, Miyawaki offers special models to handle steam locking.

    • Flexible installation

      This product can be installed either horizontally or vertically.

    • Superb durability

      The body of the product is made from stainless steel, making it durable and corrosion-resistant, even in aggressive media.

    • Auto blow off and air vent

      Thanks to a bimetal ring, the trap smoothly discharges initial air and cold condensate. (Auto blow-off mechanism)

    • Tailored design

      Manufacturing with custom face-to-face dimensions is possible. 

    Typical applications

    Suitable for F&B devices, cleaning devices, steam main lines, small heat exchangers, and other such applications.
