Steam Traps S Series | Thermodynamic Disc Steam Traps
SV-N
Models that handle steam locking also available
Features/Applications
Features
Compact and cost effective design
It has a space saving, simple mechanism with very few moving components.
Flexible installation
This product can be installed either horizontally or vertically.
Easy maintenance
The minimum of moving parts and an easy in-line access ensures easy and fast maintenance.
Auto blow off and air vent
Thanks to a bimetal ring, the trap smoothly discharges initial air and cold condensate. (Auto blow-off mechanism)
Special design against steam locking
To avoid cases of steam locking, Miyawaki offers special models to handle steam locking.
Typical applications
Suitable for cleaning devices, dish cleaning devices, dyeing devices, steam main lines, heat exchangers, and other such applications.
