Miyawaki
Miyawaki G3N Ball Float Steam Traps
Manufacturer: MIYAWAKI Inc.
Model: G3N
Features
Quick startup
Automatically discharges initial air and cold condensate. The diaphragm air vent follows the saturation temperature and prevents air and steam locking.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery.
High discharge capacity
A double ported balance valve provides a large discharge capacity in comparison with single valve models.
Typical applications
Suitable for uses including large-scale heat exchangers in various industries, and in things such as industrial plants, foodstuff devices, dyeing/cleaning devices, and air conditioning devices.

This product uses a double ported balance valve system so if the actual condensate volume is significantly lower than the product’s discharge capacity, there may be a steam leak.
