Miyawaki SU2N Thermodynamic Disc Steam Traps

Manufacturer: MIYAWAKI Inc.
Model: SU2N

Features

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 high temperature and pressure steam main lines, steam tracing, and other such applications.
