Non-compensated inline flow control valve, in chrome gray with black details.

The STB-G3/4 (DV-16-A) valves are designed to regulate flow in both directions (providing the same adjustment for both advance and return movements).

Appreciated for their aesthetic characteristics, which positively satisfy the most diverse design standards of the equipment where they are installed, the STB-G3/4 (DV-16-A) valves also present themselves as a reliable solution for the most demanding technical and functional applications.

The volumetric flow rate depends on the pressure differential and the fluid viscosity at which the valve is operating (non-compensated); that is, the regulated flow may increase or decrease depending on the variation of fluid viscosity or temperature over time. The in-line flow control valve (STB-G3/4 (DV-16-A)) allows for sensitive flow adjustment and shut-off, thanks to its special design (flow reduction).
