UNIDIRECTIONAL FLOW RESTRICTOR VALVE 1/4"
FT251U04 1/4” BSP – One-way fine flow control valve
Product description:
The FT251U04 one-way fine flow control valve is designed to allow oil flow in one specified direction only in hydraulic systems. In the permitted flow direction, the flow rate can be finely and steplessly adjusted, while reverse flow is blocked by the valve. It is suitable for applications requiring precise control of both flow direction and flow rate.
Main features:
- Type: One-way fine flow control valve
- Part number: FT251U04
- Connection (R1): 1/4” BSP
- R2 connection: M17×1
- Max. flow rate: 12 l/min
- Maximum operating pressure: 350 bar
- Housing material: OT58 brass, nickel-plated
Operating principle
This valve combines two functions in one: a check valve and a fine flow restrictor. The adjustable needle allows precise control of the flow in one direction useful for slowing down hydraulic cylinders during retraction, for example. In the opposite direction, the built-in check valve opens fully, allowing unrestricted flow and fast movement.
This makes it especially effective in applications where controlled lowering and quick lifting are required. The result is both smooth operation and efficient performance.
