Three-way low leakage rotary valve ESBE VRG 231 is made of dezincification resistant brass DZR. For easy manual operation the valves are equipped with non-slip knobs and end stops for an operation angle of 90°. The valve position scale can be turned over and rotated, allowing many different mounting positions. The scale located below the adjusting knob can be positioned arbitrarily along the heart of the mixing valve, depending on the valve orientation in the application.
