What is Dracaena ball valve: A brass ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked.Dracaena threaded valves consist of the housing, seats, ball and lever for ball rotation. They include valves with two, three and four ports which can be female or male threaded or a combination of those. Threaded valves are most common and come in many varieties: with approvals for specific media or applications, mini ball valves, angled ball valves, ISO-top ball valves, with an integrated strainer or a bleed point and the list goes on. We offer 2 options of color with a large operating range for pressure and temperature.Dracaena water cooling control valves can significantly reduce energy consumption in these systems by monitoring to control the cooling media flow. Cooling of the valve heads reduces the thermal load to which the valves are exposed. Positive effects: prolonged valve service life and minimum wear. Waste heat can be used for water for heating.
