Non-compensated in-line flow control valve – STB-G1

The STB-G1 (DV-20-A) valves are designed to regulate flow in both directions (providing the same regulation for both advance and return).

Appreciated for their aesthetic characteristics, which positively satisfy the most diverse construction standards of the equipment where they are installed, the STB-G1 (DV-20-A) valves also present themselves as a reliable solution for the most demanding technical and functional applications.

The volumetric flow depends on the pressure difference and the fluid viscosity at which the valve is operating (non-compensated), that is, the regulated flow rate may be higher or lower depending on the variation in viscosity or fluid temperature over time. The in-line flow control valve (STB-G1 (DV-20-A)) allows for sensitive adjustment and flow shut-off, thanks to the special closing design (flow reduction).
