Description
PT Temperature Pilot With Copper Bulb is directly immersed into the fluid. The PT bulb type is lowered down vertically into the top of a tank or vat to a desired vertical insertion depth.
Controlling Temperature
PT Temperature Pilot With Copper Bulb is used for temperature control when steam is used on heating applications. The PT style pilot is a “solid liquid fill” design made up of a temperature probe connected by a length of capillary tubing to a bellows in the pilot valve. When the temperature bulb is heated the liquid inside the probe expands the bellows and closes off the pilot valve. The opening and closing of the pilot controls the flow of steam thru the main valve; which maintains system temperature. PT-pilot controls temperature through a range of 60-300°F. An overheat protection bellows is incorporated into sensing bulb.
