For use with other fluids, it is crucial to verify seal compatibility.</p> <strong>How do I adjust the pressure setting on this valve?</strong><br><p>The pressure setting is adjusted via the rotary knob with a lock nut. Loosen the lock nut and turn the knob clockwise to increase the pressure and counter-clockwise to decrease it. Always use a pressure gauge to verify the setting.</p> <strong>What does the ‘Y’ in the type code DR 20-5-52/200Y signify?</strong><br><p>The ‘Y’ designation indicates that the valve has an external pilot oil drain. This means the drain line (port Y) must be connected separately to the tank, ensuring stable valve operation regardless of pressure fluctuations in the main return line (port T).</p> <p><em>spareparts2day is not an authorized distributor, reseller or representative of the products featured on this website.
