Orifice Fittings
These compact and cost effective orifice adapters allow OEMs
to pre-set, at the factory, a specified orifice in specific hydraulic
tube or hose lines. Costly flow control valves can be eliminated
or minimized in a system by selecting the proper orifice sizes at
the factory. OEMs can also be assured that end users are not
adjusting the factory established flow and speed characteristics
of the hydraulic system.
