Equlization line provided in refrigeration systems.

Used in installations with a large drop in pressure across the evaporators. In TEV the pressure acting on top of the bellow corresponded to the saturation pressure of refrigerant leaving the evaporator.
A connection is made to the bottom of the bellow directly from the evaporator exit so the saturation pressure of the refrigerant is balanced and the spring force is overcome by the pressure corresponding to the degree of superheat. So we are getting a better control over the superheat.

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
