摘要: A valve for a pipe system wherein liquid circulates is intended to be controlled dependent on the temperature within by means of thermostat adapted actuate an electro magnet which, its part, whether it current-carrying or not, retain spindle (2) in position corresponding open closed position, respectively. The housing (1) has plate-shaped seat body (5) having large central through-going flow opening (6) and number smaller openings (7) closer circumference. spring-loaded (12) first (10) displaceably arranged cooperates with order close/open said opening, concentrical, (13) hollow piece constituting second (11) which also (2), cooperating peripheric via annular flange portion (11') last-mentioned openings. two bodies (10, 11) are axially displaceable relation each other, they assigned carrier (14, 15) (2).
