G Series | Ball Float Steam Traps
Steam Traps G Series | Ball Float Steam Traps
GH3N
Stainless steel OK
Features/Applications
Features
Quick startup
Automatically discharges initial air and cold condensate.
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.
Discharge Capacity
●The discharge line chart shows the discharge rate for condensate with a temperature 6℃ (43℉) lower than the saturation temperature.
