Valve, particularly thermostatic valve for heating equipment

摘要

A thermostat valve has a casing (200), a valve seating (210) and a locking tappet (211) to be operated with a pin (208) operated outwards by a sealing device (207). A connecting device has a locating surface (221) at an initial distance (A) from the pin's free end and a first inside recess. To fasten a second type of operating cap, a connecting element (206) supporting the valve seating and the sealing device adjusts from first to a second position along the pin's axis.
