Description
The Barnes & Jones float and thermostatic traps, Series 2000 are designed for all types of
low pressure or vacuum steam heating systems and steam process equipment. Typical applications
include:
- unit heaters
- space heaters
- water heaters
- pressing machines
- low pressure mains and risers
Operation
The opening and closing of the valve is caused by changes of the condensate level within the
trap shell. When the water level drops, the weight of the float causes the valve. As condensate
enters the traps, the float rises and opens the valve, allowing condensate to be discharged.
The float is designed to provide sufficient buoyancy to overcome the differential pressure
across the valve. The internal float and valve configuration is such that the condensate level
is always above the valve, creating a continuous water seal at the seat.
Air and other gasses are freely discharged as they reach the trap through the air vent. The
calibrated thermostat will close the air vent immediately when the temperature surrounding the
element reaches saturated steam pressure.
Construction
Bearnes & Jones float and thermostatic traps are compact, of rugged design, with easy access
to all interior parts. The body is cast with two inlet and two outlet pipe connections that
permit four combinations of pipe hook-ups for all types of applications (except the 2" model
which is piped through the head.) All working parts are made of corrosion resistant
materials and attached to the cover casting. The repair kit consists of a complete, factory
assembled head which simply bolts on for ease of repair (except the 2" model
which is piped through the head.) No pipe connections need to be broken.
