VFD50 Series Variable Priority Flow Dividers VFD50-15-T SINGLE PACK | TSK5453-10

Description & Features

Part of the VFD50 Series, the WEBTEC VFD50-15-T is a variable priority flow divider suited to applications where adjustable hydraulic flow distribution is required. It handles flows up to 15 L/min (3.9 US gpm) at pressures up to 250 bar (3600 psi), with a continuously adjustable range starting from zero, giving operators direct control over actuator speed without additional valving.

The unit is built around a cast SG Iron body with steel components, hardened steel internals, and a high carbon spring steel mechanism, providing durability under sustained hydraulic load. NBR seals support compatibility with mineral oils to ISO 11158 across a fluid temperature range of -30 to 120 °C (-22 to 248 °F). Porting is 3/8" BSPP. At 0.8 kg, the compact form factor suits space-constrained installations. Ambient service temperature is rated from -30 to 50 °C (-22 to 122 °F).

Question by: Mike P on Feb 7, 2026, 8:31 PM
porting on this is 3/8 BSPP right? trying to figure out if it'll drop into an existing manifold we've got without repiping the whole thing
Answer by: Customer Support on Feb 9, 2026, 8:00 AM
3/8 BSPP is correct. If your manifold is already threaded for BSPP at that size, it should fit without modification. Worth double-checking thread form before you commit, since BSPP and NPT look similar but won't seal correctly together.

Could this flow divider handle a system running at 250 bar pressure?
Answer by: Customer Support on Dec 7, 2025, 7:33 AM
Yes, this flow divider can handle up to 250 bar (3600 psi) pressure, making it suitable for high-pressure hydraulic systems.
