  • Description

    Actuated Butterfly Control Valves, butterfly control valve actuator, control the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle, which permits flow in only one direction. These valves offer                         a rotary stem movement of 90 degrees or less, in a compact design.

    EE Series designed to withstand harsh environmental conditions and still deliver the performance- consistently. A butterfly valve is from a family of valves called quarter-turn valves. The “butterfly” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

    Stolzel offers actuators specially developed for automation of small valves & dampers. Low power motor packed within compact enclosure offer best in class power-weight ratio and space saving design – simple to mount, operate and maintain.
