Flow control valve using non compensated throttling.
The flow is reduced in one direction only, from 2 to 1, for SU valves and in both
directions for SB valves.
Guarantees excellent mechanical seal with negligible leakage.
It has a galvanised steel body. The check valve guided ball poppet is in tem-
pered and ground steel.
