  • Adaptable to almost any drain size

Design Features

Design Features

 N/A
  • Exclusive Thermoloid® thermal actuator
  • Rugged, clog resistant valve design
  • Install using standard pipe fittings and tools
  • Operates in any orientation
  • Modulates to conserve cooling water
  • Effluent tempering capacity limited only by cold water flow rate through DTV

Applications

Applications

 N/A The DTV can be used in applications where a high temperature discharge flow to a drain/sewer must be tempered with cold water.

Examples:
  • Humidifier discharge to sewer/drain
  • Commercial dishwashers/warewashers
  • Boiler blowdown drain lines
  • Autoclave discharge
  • Any excessively hot effluent flow to sewer/drain

Operations

Operation

 N/A The DTV is installed into the drain line such that the hot effluent passes over the thermal actuator of the DTV and this thermal actuator controls the cold water inlet port. If the hot effluent is above the specified set-point, the DTV opens to allow injection of cold water. As the hot effluent cools, the DTV automatically modulates to reduce the cold water inlet fl ow. At 10 ºF below the full open temperature, the cold water inlet is fully closed to conserve water.

Since the DTV is open only when the effluent exceeds the specified set-point temperature, it conserves water by automatically turning off cold water when not needed.

Note

Note

 N/A
  1. Full open temperatures “XXX” available: 120 ºF, 125 ºF, 130 ºF, 140 ºF.
    • Other temperatures are available, consult our engineers for more information.
    • Closing temperature is typically 10 ºF below opening temperature.
  2. If any type of check valve or backflow preventer is used a water hammer arrestor must be installed between the DTV water inlet and the check valve/backflow preventer. Failure to do so may cause permanent damage to the valve and void the warranty
