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.

Installation

The valve should be installed in horizontal pipe line under vertical position. The flow direction must be in the arrow direction.
The supply voltage must meet the rated input voltage shown on the label of the coil. Coil taking away from valve when energized in coil is forbidden.
When brazing the valve with connect tube in system,follow points are very important.
Before brazing, coil must be taken away and with wet rags covering the valve body to avoid damage.
The brazing flame must be avoided facing the valve body.
 It is better to use low temperature type silver to braze.
For the valve with hand lever,you must turn the lever firstly,then make leakage test to protect diaphvagm.
