Manufacturer: MIYAWAKI Inc.
Model: S61N

Features

Versatile steam trap
It is a wide range of operating pressure. Thus, it can be used for many kinds of applications.

Flexible installation
This product can be installed either horizontally or vertically.

Superb durability
It is equipped with additional cover for improvement of thermal efficiency, and reduced frequency of cycling. It improves durability.

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 a wide range of applications such as steam main lines and steam tracing.
