Request Information
Spring loaded regulators are used primarily for standard drilling operations and are designed to automatically return to their position at the end of every drilling cycle.
With the RB spring return regulator, the piston rod is automatically returned to its original position by the built-in spring when the piston rod is no longer loaded.
