<p>A thermostatic control valve for regulating the supply of fluid through a conduit including in combination a valve plate and seal in the conduit, the valve plate having a valve stem extending outwards of the conduit with a valve stem having a spring exterior of the conduit to move the valve stem and plate away from the seal and a housing secured to the conduit with a retractable plunger in the housing operative on the valve stem. The plunger is contained in a casing with means in the casing responsive to change in ambient temperature moving the plunger against the valve stem towards the seat. An interior member is threaded in the housing and removable means are provided for attachment to the interior member to rotate it in the housing, the arrangement being such that the threaded interior member and the casing are adapted for contact whereby the rotation of the threaded interior member causes adjustment of the position of the plunger with respect to the seat.</p> |
