Model 2470 External Sensing 2-Way Valve (1" | DN25)

SKU 2470

The 2470 is a two-way temperature regulating valve with remote sensing to modulate or shut off flow resulting from temperature changes. It can be used to sense the regulating medium or another fluid. The 2470 valve uses a highly reliable expanding wax element encased in a bronze retaining cup, which produces exceptional valve travel per unit of temperature change. Where additional element insertion length is required, extensions can be added. Stainless steel wells are also available for use in corrosive environments or where fluid containment is necessary.

Features and Benefits

  • Tamper-Proof Temperature Settings 21 to 121˚C (70 to 250˚F)
  • External Sensing for Liquid Service
  • Open or Close On Rising Temperature
  • Conserves Water and Steam
  • Alternative option is our external sensing Model J thermostatic valve

Operation

MODEL 2470B(-)1

 
Opens with a rise in temperature above the setpoint and will close on falling temperature. With a valve seat of Nitrile rubber this unit, when fully opened, will withstand 8.6 bar (125 psi) water pressure without leaking. To obtain maximum life from the temperature elements the valve must not be operated continuously at more than 30˚C (50˚F) above the opening point. If it is necessary to operate at a continuous overtemperature, consult the factory for alternative elements.
 

MODEL 2470B(-)3

 
Closes with a rise in temperature above the setpoint and will open on falling temperature.  With a valve seal of Nitrile rubber this unit, when fully closed, will withstand 8.6 bar (125 psi) water pressure without leaking, To obtain maximum life from the temperature elements the valve must not be operated continuously at more than 18˚C (30˚F) above the opening point. If it is necessary to operate at a continuous overtemperature, consult the factory for alternative elements.
