Flow control valve using non compensated throttling.
The flow is reduced in only one direction (A to A1) for VSR valves and in both
directions for VSB valves, by turning the outer casing of the valve right or left.
Slight leakage is tolerated when the control screw or wheel is completely
unscrewed.
It has a galvanised steel body. The check valve ball poppet is in tempered and
ground steel.
