Type IEV Valve

IEV
INSTRUMENT ENCLOSURE VALVE...
a compact steam control device that provides precise, reliable, economical temperature control in instrument and analyzer enclosures ... the safe, low cost alternative to electric heating systems.

The IEV valve is a safe, low cost alternative to electric heating systems. Installed in the steam supply line, it controls the flow of steam to maintain enclosure temperature to within ± 3°F.

Available with standard pre-calibrated control points of 45°, 50°, 75°, 100° and 190°F

Allows the Use of Steam as a Heating Medium for Instrument Enclosures

The self-contained IEV valve allows steam to be an economical and reliable alternative to costly and potentially hazardous electric heating. Installed in the steam supply line, this compact thermostatic control valve senses enclosure temperature and automatically regulates the flow of steam to maintain the desired temperature.

eliminates the danger of explosion due to sparking and the expense of explosion proof controls

Thermal actuator controls flow of steam to instrument enclosure as needed
Eliminates danger of overheating temperature sensitive instruments or analyzers
Provides effective freeze-protection
Can be safely used in all environments, no explosion proof housings or other precautions are necessary
Calibrated actuators are interchangeable for quick easy change of enclosure temperature
Direct acting (no pilot valve)
High repeatability, no control point drift
Valve port opens gradually, preventing system shock
Temperature control points from 40° to 190°F
Maintain enclosure temperature to within +/- 3°F of control point over a wide range of ambient temperatures and steam supply pressures
100% factory tested

Accurate temperature control is assured with an IEV valve. The unique thermal actuator will maintain instrument temperature within +/- 3°F of control point over a wide range of ambient temperatures, with steam supply pressures from 15 psi to 200 psi. Overheating the instrument or analyzer is effectively eliminated.

IEV valves are available with standard interchangeable pre-calibrated control points of 40°, 50°, 75°, 100°, and 190°F... other control points are also available. A quick exchange of actuators is all that is required to change instrument enclosure temperature.

Self-contained Thermal Actuator
At the heart of the IEV valve is the unique solid-liquid phase thermal actuator. This hydrocarbon wax filled device actuates the valve in response to changes in enclosure temperature.
