PT Temperature Pilot With Copper Bulb

PT Temperature Pilot With Copper Bulb is directly immersed into the fluid. Normally the PT bulb type is lowered down vertically into the top of a tank or vat to a desired vertical insertion depth.

The PT-Temperature Pilots are used with the HD regulator to control temperature in various processes and systems. Some examples are: oil heaters, ovens, process heaters, vats, dryers and jacketed kettles. Thermostatic sensing bulb comes with standard 8-ft. or 15-ft. capillary lengths. Temperature adjustment is accomplished by rotating an adjustment knob to the desired temperature setting.

The HD Regulator can be used with both the PP-Pressure Pilot and PT-Temperature Pilot simultaneously to limit pressure and control temperature in process applications.

  • Temperature adjustment made simple and easy by rotating an adjustment knob to the desired temperature setting
  • Thermostatic sensing bulb comes with an 8-ft. or 15-ft. length capillary
  • Capillary is armor-protected to resist damage
  • Overheat protection bellows is incorporated into sensing bulb; 200°F overheat protection up to 350°F
  • Full port strainer and blowdown valve on pilot adapter for protection of pilot from dirt and scale

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.
