UNIDIRECTIONAL FLOW RESTRICTOR VALVE 1/2"
FT251U12 3/4” BSP – One-way fine flow control valve
Product description:
The FT251U12 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 a reliable solution for higher flow applications where precise and stable flow control is required.
Main features:
- Type: One-way fine flow control valve
- Part number: FT251U12
- Connection (R1): 3/4” BSP
- R2 connection: M30×1.5
- Max. flow rate: 85 l/min
- Maximum operating pressure: 350 bar
- Housing material: OT58 brass, nickel-plated
Operating Principle
This valve integrates a needle-type flow restrictor and a check valve in a single unit. When flow moves in the restricted direction, it passes through the adjustable needle, allowing precise control over movement speed such as controlled descent of a hydraulic actuator.
In the opposite direction, the check valve fully opens, enabling fast, unobstructed flow. This configuration ensures both efficient system performance and safe, smooth operation in demanding hydraulic applications.
