Flow regulators by rotating knob

STUF-SAE (UNF thread) allows free oil passing in one direction and regulates the flow on the opposite one. Generally, it is mounted between the cylinder and the check valve



It is used to regulate the oil in one sense and have the full flow on the opposite one, it is not pressure compensated so the setting depends on the application pressure, the oil viscosity and the oil temperature. The range includes sizes from SAE4 up to SAE24. This version has the external thread for nut tightening. Setting is made by knob rotation clockwise and vice versa. Once the valve is set, thighten the lateral nut placed on the knob to lock the setting. It does not allow leakages. The external body is made by high resistance steel and externally protected from oxidations by zinc treatment. On request we can supply a zinc/nickel treatment to increase the oxidation resistance when the valve has poor protection or it is located in external environments
