4033 – By Pass Valve

The Valve 4033 is realized in several dimensions and allow to by pass the flow when the set pressure is achieved.
The disk has parabolic shape to have a very smooth action even with very small flow to be discharged.
The disk is provided with an O-Ring that doest allow the Turbine oil to go in the upper par of the valve. The valve is fitted with a ¼” Thread that allows to keep pressurized the upper part of the valve and to avoid any loss
