Miyawaki G5 Ball Float Steam Traps

Manufacturer: MIYAWAKI Inc.
Model: G5

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.

G5

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.

Discharge Capacity

The discharge line chart shows the discharge rate for condensate with a temperature 6℃ (11℉) lower than the saturation temperature.
