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¡É
B. Chilled water : -25¡É Max. In closed circuit Only water with following additives.
C. Hydrazine, Phosphate, for frost protection
D. Glycol, max. 50%, for frost protection |
