    Rock-burst valvesHYDRAULIcs & Mining technology

    A rock-burst (rapid-yield) valve has the function of limiting the pressure in the hydraulic prop to a set value.

    The valve is attached to a prop beside the pressure-limiting valve and has the task of protecting the roof support against sudden tension releases (bursts) in the rock.
