Advantages

— the excentric rotating plunger provides high tightness in a lock and small dynamic efforts from a stream;

— high capacity thanks to an optimum design of flowing part;

— a reliable epiploon with shevronny rings from PTFE with the duplicating rings on the omental plug;

— reliable mechanical connection of lining with a metal basis of the case "in a larkspur";

— installation of a cam of a positioner directly on the end of a shaft increases regulation accuracy;

— mobile parts of the drive are completely protected by a casing;

— easy and compact, but at the same time strong design.
