Technical data
The Kv value is the water flow in m3/h at a pressure drop across valve of 1 bar,ρ=1000kg/ m3.
Note :If you have special requirement ,please contact STF.
Nominal Liquid Capacity(KW)
Rated liquid and suction vapour capacity is based on evaporating temperature te=4.4℃,liquid temperature ahead of valve t1=38℃,and pressure drop in valve R134a △P=0.15 bar, R22、R404A、R507、R407c、R410A ΔP=0.21bar.
Rated hot gas capacity is based on condensing temperature tc=+40℃,pressure drop across valveΔP=0.8bar,hot gas temperature th=+65℃,and subcooling of refrigerant Δtsub=4K.
