G Series | Ball Float Steam Traps
Steam Traps G Series | Ball Float Steam Traps
G12N
Features/Applications
Features
No condensate logging on primary side (continuous discharge float system)
The floating mechanism discharges condensate immediately at saturation temperature, preventing condensate logging on the primary side. Ideally installed in applications where condensate logging cannot be accepted.
Easy maintenance
For quick and easy maintenance, all valve parts are attached to the cover, making maintenance easy. The trap can be serviced directly in line.
Superb sealing and durability
Offers superb sealing and durability thanks to the MIYAWAKI SCCV System.
This valve mechanism was developed by MIYAWAKI to increase valve durability and ensure maximum sealing performance.Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery.
Free from steam and air locking
A quick start up is guaranteed, thanks to a diaphragm air vent. The air vent follows the saturation temperature and prevents air and steam locking.
*’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.
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.

●Maximum allowable pressure (PMA): 1,6MPa (230psig) PMA is the pressure that can be tolerated by pressure-resistant parts (body).
●Maximum allowable temperature (TMA): 220℃ (428℉) TMA is the temperature that can be tolerated by pressure-resistant parts (body).
●Minimum operating differential pressure (⊿PMN): 0,01MPa (1.5psig) ⊿PMN is the minimum operating differential pressure between the trap inlet and outlet.
