GXS213路控制閥3-WAYCONTROLVALVE(Bronze)(GXS21series(GXS21

詳細介紹

GXS21 3路控制閥3-WAY CONTROL VALVE(Bronze)(GXS21 series (GXS21.15 - 50))

The valve which controls two positions or the proportion of cold/hot water, steam and air. The body and the seat are manufactured in bronze, the valve stem stainless steel, and valve plug, STS. The stuffing box prevents leakage by using an O-ring.
The feature curve of the valve is equal percentage or linear type.

Hot water : max. 130℃
Chilled water : -25℃ max. in closed circuit only Water with following additives ;
Hydrazing, Phosphate, for frost protection
Glycol, max. 50%, for frost protection
Saturatecd steam, superheated steam abs. press. 1.5bar 120℃.

※ Close-off pressure
