UNIDIRECTIONAL FLOW RESTRICTOR VALVE 1/2"
FT251U08 1/2” BSP – One-way fine flow control valve
Product description:
The FT251U08 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. It is an ideal solution for higher flow applications where precise speed control is required.
Main features:
- Type: One-way fine flow control valve
- Part number: FT251U08
- Connection (R1): 1/2” BSP
- R2 connection: M25×1.5
- Max. flow rate: 45 l/min
- Maximum operating pressure: 350 bar
- Housing material: OT58 brass, nickel-plated
Operating principle
This valve combines a fine-adjustment needle flow restrictor and a check valve in a single unit. In one direction, the flow passes through a calibrated restriction, allowing you to control the speed of movement (e.g., slow lowering). In the opposite direction, the check valve opens fully to allow free flow enabling fast motion such as quick lifting.
This intelligent setup improves operational efficiency and extends the life of the hydraulic system by reducing mechanical stress.
