55926 AIGNEP — Angled Swivel Two-Way Flow Control Valve without Check Valve, M5-4 mm, for Actuator

Technical specifications

Series features

• Two-way flow control. Unlike flow control valves with a check valve (e.g. AIGNEP 55905), this type restricts flow in both directions — suited where symmetric adjustment is needed rather than separate extend/retract speed settings.
• Manual adjustment, no tool. The protruding knurled screw is adjusted by hand — quick on-site tuning, unlike screwdriver-adjusted versions (56900/56920 series).
• Angled swivel body. The banjo rotates freely around the thread axis — convenient for orienting the tube after the fitting is already screwed into the port.
• Compact and lightweight. The technopolymer body reduces stress on the threaded connection, important when mounting on pilot M5 ports of valves and small actuators.
• Needle adjustment mechanism. Provides smooth, repeatable flow adjustment without sudden jumps.

Application areas

• Symmetric flow adjustment on pilot control lines, where no difference between extend and retract speed is needed.
• Damping pneumatic pulses and stabilizing signal fronts in compact schemes built on M5 ports.
• Small actuators and valves where M5 thread is the only available port size.
• Settings that operators adjust frequently during commissioning — a knurled thumb screw adjusts faster than a screwdriver-type version.

Important when choosing

The main difference from the AIGNEP 55905 angled swivel flow control valve (check valve series) is the absence of a check valve: that model restricts flow in only one direction while allowing free passage in the other, whereas the 55926 restricts flow equally in both directions. If you need different extend and retract speeds on your actuator — choose a flow control valve with a check valve (55900/55905/55910/55912 series); if you need equal, symmetric adjustment in both directions — choose the 55926, without a check valve. Also don’t confuse it with the 56900/56910/56920 series — they look similar and are also check-valve-free, but are adjusted with a screwdriver rather than a manual knurled screw. Confirm the exact part number suffix for your connection with your manager — the 55926 family is produced in various thread/tube diameter combinations, and M5-4 mm requires the specific size code.

Frequently asked questions (FAQ)

How does this flow control valve differ from the AIGNEP 55905? The 55905 has a check valve — flow is restricted in only one direction, passing freely in the other. The 55926 has no check valve, flow is restricted equally in both directions.

How does the 55926 differ from the 56920 series — aren’t both without a check valve? The adjustment method differs: the 55926 has a protruding knurled screw for finger adjustment, the 56920 has a recessed element for a screwdriver. The flow control function (in both directions) is the same for both series.

Can this flow control valve be used to adjust cylinder speed in one direction only? Not ideal — for separate extend/retract speed adjustment you need a flow control valve with a check valve, otherwise changing the setting affects both directions at once.

What tube diameter fits? Tube with a 4 mm outer diameter — a standard push-in connection for this size.

Does the M5 thread need PTFE tape? The thread is parallel (cylindrical), not self-sealing — sealing depends on the fit and the sealing ring; if in doubt, check the exact seal configuration with your manager.
