Hydraulic valve

A hydraulic manifold for use in a hydraulic heating system or cooling system or both a hydraulic heating and cooling system with one or more hydraulic valves comprising:

• a valve housing with an interior defining at least one flow path, the valve housing comprising a valve housing inner surface defining at least a portion of the at least one flow path, wherein the valve housing inner surface coincides with a boundary of the at least one flow path;
• a valve insert arranged in the inside of the valve housing, the valve insert comprising a movable valve element situated in the flow path;
• and
• an infrared temperature sensor arranged on or in the valve housing, the infrared temperature sensor being directed onto a surface of the valve insert or onto a surface of a thermal conductor connected to the valve insert, wherein one of:
• at least a section of the valve insert, on which the surface of the valve insert is located, onto which the infrared temperature sensor is directed, is formed from a material which comprises a greater thermal conductivity than the material of the valve housing;
• and
• the thermal conductor is formed from a material which comprises a greater thermal conductivity than the material of the valve housing.

A hydraulic manifold comprising a plurality of hydraulic valves which are connected to one another in a manner such that at least flow paths of the hydraulic valves are connected to one another, at least one of the valves comprising:

• a valve housing comprising an interior surface defining at least a portion of one of the flow paths, wherein the interior surface coincides with a boundary of the one of the flow paths;
• a valve insert arranged in the inside of the valve housing, the valve insert comprising a movable valve element situated in the flow path;
• and
• an infrared temperature sensor arranged on or in the valve housing, the infrared temperature sensor being directed onto a surface of the valve insert or onto a surface of a thermal conductor connected to the valve insert, wherein one of:
• at least a section of the valve insert, on which the surface of the valve insert is located, onto which the infrared temperature sensor is directed, is formed from a material which comprises a greater thermal conductivity than the material of the valve housing;
• and
• the thermal conductor is formed from a material which comprises a greater thermal conductivity than the material of the valve housing.
