WARNING
sure the vent outlet is not obstructed by rain, snow, ice,
vegetation, insects, birds, etc. Do not interconnect vent
lines; use separate lines if more than one vent is needed.
•
Do not locate regulators, valves or accessories controlling
flammable fluids near open flames or any other source of
ignition.
•
Some fluids when burning do not exhibit a visible flame.
Use extreme caution when inspecting and/or servicing
systems using flammable fluids to avoid death or serious
injury to personnel. Provide a device to warn personnel of
these dangerous conditions.
•
Many gases can cause suffocation. Make certain the area
is well ventilated. Provide a device to warn personnel of
lack of Oxygen.
•
Never use oil or grease on these regulators unless
recommended as specified in Operations and Service
procedures. Oil and grease are easily ignited and may
combine violently with some fluids under pressure.
•
Have emergency equipment in the area if toxic or
flammable fluids are used.
•
Upstream filters are recommended for use with all fluids.
•
Do not bleed system by loosening fittings.
•
Prevent icing of the equipment by removing excess
moisture from the gas.
•
Always use proper thread lubricants and sealants on
tapered pipe threads.

3.1 General Information
TESCOM 44-6800E Series Electrically Heated Vaporizing
diaphragm-sensed pressure reducing regulators are specifically
engineered for applications requiring dependable pressure
regulation. These regulators are especially appropriate for
installations where high system pressures (up to 6000 psi) must
be reduced to levels suitable for actuating low pressure (0 psig/0
bar to 500 psig/35 bar) instruments and related equipment.
In addition, the 44-6800E Series “Vaporizing” regulator is
designed to offset the effects of the Joule-Thompson cooling
effect that occurs when there is a pressure drop in a gas. It can
also be used to vaporize a liquid into a gas in some applications.
The electrical board inside the housing powers an electrical
heater that indirectly heats the process media. This heater is
controlled by the electrical board for temperatures ranging from
122
⁰
F/50
⁰
C to 752
⁰
F/400
⁰
C. There is a thermocouple within
the heater core to provide temperature feedback. There is a
secondary thermal device, thermal cut off (TCO), within the
regulator assembly.

3.2. Installation
3.2.1. Installation Precautions
Make sure that the components and materials used
in the fluid handling system are compatible with the
fluid and have the proper pressure rating. Failure
to do so can result in death, serious injury and/or
property damage.
A regulator is not intended to be used as a shutoff
device. When the regulator is not in use, the inlet
