1 Hydraulic Linear Actuator HKV BESI produces the single acting HKV, spring return type. This single acting hydraulic actuator type HKV can be built to several type s of seat valves (as globe stop valves, non return valves, valve chests). The hydraulic oil pressure (abt bar) acts in one way and disc springs in reverse direction, the normal action is: Function With hydraulic pressure valve to open resp. Cone released, and without hydraulic pressure spring forces will close the valve also against some medium pressure against cone. Design Most important is the design of stuffing box part: There are three automatic sealings, one against hydraulic part, one against medium part, the third is also on medium side but main point is the distance between all 3 sealings is more than stroke. Emergency operation Standard design is the actuator with 2 nd piston for emergency control, but also possibilities for mechanical control with hexagon screw or a special design for overriding the manually opened valve are on request available. And a special design is available for hanging execution. Mounting in submerged conditions Mounting under medium is possible for the complete construction. Material of the intermediate flanges is in accordance with the valve body material. Additional equipment On the actuator can be mounted: Mechanical position indicator (for dry mounted valves) Electric limit switch for open close position transmitting Throttles, non-return valves and also safety valves patent grant or registration of a utility model for design are reserved.
