Automatic valve manufacturer, For Power plant, Energy, Petro chemical, Oil refining, Food, Paper, Shipbuilding, Pharmaceutical field
General
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. The stuffing box prevents leakage by using an O-ring and Vition.
The feature curve of the valve is equal percentage or linear type. The elevation of stem by the actuator close the valve.
A. Hot water : Max 130℃
B. Chilled water : -25℃ Max. In closed circuit Only water with following additives.
C. Hydrazine, Phosphate, for frost protection
D. Glycol, max. 50%, for frost protection

Pvmax in Kgf/㎠ = max, prem, pressure difference across the valve at which the drive can still safely
......................................open and close the valve.
Psmax in Kgf/㎠ = max, prem, pressure difference across the valve during malfunction at which the
......................................drive can close the valve.
