Products classified under HTS 8481.20.00.40
Hydraulic Throttle Valve
A hydraulic throttle valve regulates the flow rate of hydraulic fluid in transmission systems by adjusting the opening size. It falls under HTS 8481.20.00.40 as a flow control type valve specifically designed for oleohydraulic transmissions in machinery like presses and excavators.
Hydraulic Flow Restrictor Valve
This valve restricts hydraulic fluid flow to maintain consistent speeds in actuators. Classified in HTS 8481.20.00.40 for its flow control mechanism in oleohydraulic transmission systems of construction equipment.
Hydraulic Priority Flow Control Valve
Priority flow valves allocate hydraulic flow preferentially to essential circuits like steering before secondary functions. HTS 8481.20.00.40 covers this flow control type for oleohydraulic systems in agricultural tractors.
Hydraulic Meter-In Flow Control Valve
Meter-in valves control flow into actuators for speed regulation on extension strokes. HTS 8481.20.00.40 specifically identifies this flow control type for oleohydraulic transmission applications.
Hydraulic Needle Flow Control Valve
Needle valves provide fine adjustment of hydraulic flow through tapered needle mechanisms. As flow control type for oleohydraulic transmissions, classified in HTS 8481.20.00.40 for precision machinery.
Hydraulic Diverter Flow Control Valve
Diverter valves proportion hydraulic flow between multiple circuits while controlling total flow. HTS 8481.20.00.40 covers this flow control functionality for oleohydraulic power transmissions.
Hydraulic Compensated Flow Valve
Compensated valves maintain constant flow despite varying pump pressures using internal compensation mechanisms. This flow control type for oleohydraulic transmissions is classified under HTS 8481.20.00.40.
