G Series | Ball Float Steam Traps
Steam Traps G Series | Ball Float Steam Traps
GWH70
Features/Applications
Features
Suitable for medium capacity steam processes
Capable of moving continually to change the degree of valve opening according to the incoming condensate to provide maximum heat exchange capacity.
High discharge capacity
A double-port balanced valve is adopted to discharge larger capacity with a smaller body.
Easy maintenance
Internal screen can be taken out quickly and easily without removal of trap from pipe line.
Countermeasure against erosion
Use of stainless steel components at the outlet which is subjected to erosion by the condensate flow.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery.
Quick startup
Internal thermostatic air vent automatically discharges of air/gases and cold condensate during startup.
Typical applications
Suitable for high pressure process equipment
