An apparatus for the relief of grease under pressure in the delivery line of grease guns and similar pressure delivery devices includes a 3-port valve in which the relief port is located between the delivery and inlet ports and includes a one way flow control valve mounted therein. The one way flow control valve is maintained in a closed position by the pressure of the grease and is activated to be opened to reduce the pressure in the valve body and allow the grease to return to the grease reservoir.
