Abstract: This invention relates to valves (2) for heat exchanger thermostats (1), thermostat heads (3) for a heat exchanger thermostat (1) and a heat exchanger thermostat (1) comprising a valve (2) and a thermostat head (3). According to the invention, temperature sensitive means (10) are provided on or within said valve (2) and/or said thermostat head (3) influencing a throttling behavior of said valve (2) depending on a temperature of a fluid controlled by said valve (2). By this, a premature throttling of the fluid controlled by said valve (2) due to heat transfer between the fluid and the thermostat head (3) may be prevented. Thus, a good ambient temperature may be established which comes closer to the desired room temperature.

Abstract: The invention relates to a flow adjustment valve (1) comprising a valve housing (2) having a flow channel (3) and a pipe stub (10), disposed at an angle to the flow channel (3). A throttle unit (6) is arranged in the flow channel (3) and comprises a throttle element (8) that can be actuated through the pipe stub (10). The flow adjustment valve also comprises two measuring points (14, 15) for detecting the pressure in the flow channel (3) at both sides of a throttle arrangement, each of which measuring points being connected to a pressure measuring connection (17) via a pressure measuring channel (26, 27). The aim of the invention is to improve the design options for a flow adjustment valve of the aforementioned type. For this purpose, at least one pressure measuring channel (26) is guided through the pipe stub (10).

Abstract: The invention relates to a flow adjustment valve (1) comprising a valve housing (2) having a flow channel (3) in which a throttle unit (4, 11) having an adjustable throttle element (11) and a shut-off unit having a shut-off element (4) which blocks the flow channel (3) in a closed position are arranged, the shut-off element (4) being actuatable from the outside by means of a handle (16). The aim of the invention is to simplify the handling of a flow adjustment valve of the aforementioned type. For this purpose, the throttle element (11) can also be actuated by means of the handle (16).
