It has improved airtightness, minimum hysteresis between opening and closing pressure, improved operational safety in work in aggressive media and vibrations. It consists of a casing (1) and cover (12), a basic plunger (4) fixed to cover (2) and supplementary diaphragm (20) movably housed in the casing. Basic spring (6) stretched in nut (19) presses the plunger to the casing. Bushing (9) is fixed both to the diaphragm (11) and the plunger (4). Supplementary plunger (7) is mounted in the first plunger (4) and is pressed to it by an auxiliary spring (8) stretched by a nut (18).
