Profile: Blackfive Engineering Ltd. is a manufacturer of industrial valves. We serve various industries. A wide range of valves are available with us. Our series 1 low contamination safety sampling valve is suitable for the chemical and process industries. Our series 2 near flush ball valves for base of vessels is a conveniently angled near flush valve. It is hand lever or actuator operated. A special pad is placed on the base of the vessel. By design, the ball is nearly flushed with the base of the vessel, thereby avoiding product hold up and blockage in a spigot. The body chamber around the ball is machined spherical to minimize contamination. The valve can be cleaned in-situ by the use of special side tappings in the valve body. Piston sample valves, pipeline sample valves, and road tanker valves are other valves we offer.
