G Series | Ball Float Steam Traps
Steam Traps G Series | Ball Float Steam Traps
G30
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.
Quick startup
Automatically discharges initial air and cold condensate. The diaphragm air vent that follows the saturation temperature and prevents air and steam locking.
Outstanding sealing performance
Achieves high sealing performance and reduces steam loss due to a precision polished float. The float is specially manufactured to comply with the maximum requirements for shape precision and surface tolerance.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery.
Typical applications
Suitable for use in foodstuff devices, cleaning devices, air conditioning devices, and other such applications.
