Uncompensated In-Line Flow Control Valve – STB-G3/8

The STB-G3/8 (DV-10-A) valves are designed to regulate flow in both directions of the valve (with the same setting for both advance and return).

Valued for their aesthetic characteristics, which positively meet the most diverse construction standards of the equipment in which they are installed, the STB-G3/8 (DV-10-A) valves also stand out as a reliable solution for the most demanding technical and functional applications.

The volumetric flow depends on the pressure differential and the viscosity of the fluid in which the valve is operating (uncompensated), meaning the regulated flow rate may be higher or lower depending on variations in fluid viscosity or temperature over time. The In-Line Flow Control Valve (STB-G3/8 (DV-10-A)) allows for sensitive flow adjustment and shut-off, thanks to its special closing design (flow reduction).
