This invention provides for a valve system for use in fire suppression systems that provides pressure relief, pressure testing, and drain/test fluid flow capability. The valve system consists of a valve body with an attached riser. Adjustably attached to the riser is a rotary handle for raising and lowering a spring loaded valve stem. A blocking plug is provided for attachment to the handle which operates to block the movement of the valve stem during pressure testing of the fire suppression system. A tension disk is adjustably attached to the inside of the riser to manually adjust the spring tension. In addition, a means is provided for preventing system fluid from contacting the spring.
