The Ogontz TL valve is a fully self-contained, temperature-actuated control valve. It effectively eliminates steam waste by automatically regulating the supply of steam in response to changes in ambient temperature. As a result, the TL valve achieves dramatic reductions in the amount of steam consumed, with annual savings averaging eight times its installed cost. High reliability, low maintenance and long service life are assured by the state-of-the-art, precision thermal actuator. The TL valve completely eliminates the use of hazardous, chemically filled diaphragms, delicate capillaries or thin-walled bellows. The TL valve continuously monitors ambient temperature, and regulates steam flow on an as needed basis. This eliminates steam waste and substantially reduces the possibility of overheating. The TL valve is ideal for steam-traced lines of all types, protecting temperature sensitive instrumentation, winterizing product lines, conserving energy in unit heaters, and other applications requiring control of heat transfer media (i.e. glycol, hot oil, water, etc.) based on ambient temperature change. The TL ambient sensing valve is the key to positive, year-round protection of your systems and equipment at the lowest cost.Design Features
  • Direct acting (no pilot valve)
  • Self-contained, solid-liquid thermal actuator requires no external power or operating signal
  • High repeatability — no set point drift
  • Valve port opens gradually, preventing system shock
  • Fail safe (valve opens)
  • Temperature set points from 35°F to 240°F
  • In-line serviceable
  • Line sizes 1/2" through 2"
  • 100% factory tested
Self-Contained Thermal ActuatorThe heart of the TL valve is the unique, solid-liquid phase thermal actuator. This hydrocarbon wax-filled device actuates the valve in response to changes in ambient temperature. The transition from solid to liquid phase causes a large change in volume, exerting a tremendous force over a narrow temperature band.
