G Series | Ball Float Steam Traps
Steam Traps G Series | Ball Float Steam Traps
GH70D
Stainless steel OK
Features/Applications
Features
Quick startup
An internal air vent automatically discharges the initial air and cold condensate. The diaphragm air vent follows the saturation temperature and prevents air and steam locking.
Suitable for medium to high capacity steam processes
Adjust the degree of valve opening according to volume of condensate generated to provide maximized heat exchange capacity.
Condensate recovery
With a high degree of back pressure tolerance, this model supports condensate recovery.
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.
High discharge capacity
A double ported balance valve provides a large discharge capacity in comparison with single valve models.
Typical applications
Suitable for use in industrial plant systems, foodstuff devices, and dyeing/cleaning devices.

*Available flange standards: ASME/JPI 150lb, 300lb, DIN PN40, JIS 10K, 16K, 20K
●Maximum allowable pressure (PMA): 4,0MPa (580psig)
●Maximum allowable temperature (TMA): 400℃ (752℉)
●Maximum operating back pressure (PMOB): 90% of inlet-side pressure
*ASTM material (WCB) on request.
●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.
