G Series | Ball Float Steam Traps
Steam Traps G Series | Ball Float Steam Traps
G20N
Features/Applications
Features
Suitable for steam process lines
The floating mechanism discharges condensate immediately at saturation temperature, preventing condensate stacking up on the primary side. Ideally installed in applications where condensate logging cannot be accepted.
Time shortening to start up
Automatically discharges initial air and cold condensate. The diaphragm air vent follows the saturation temperature and prevents air and steam locking.
Energy saving design
Achieves high sealing performance even in situations with extremely small amounts of condensate and reduces steam loss thanks to a precision polished float and three point support mechanism.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery.
Typical applications
Suitable for use in F&B process equipment, cleaning devices, air conditioning and similar applications.
