Steel Liquid Drain Trap FA450

Steel Liquid Drain Trap FA450
Steel Liquid Drain Trap
FA450
The float-operated liquid drain
trap discharges
continuously in
direct response to
variations in liquid
flow rate, assuring
thorough drainage
of the system.

Steel Liquid Drain Trap
FA450
Capacity
The discharge capacity depends on the differential pressure
(inlet pressure minus outlet pressure) and the specific gravity of
the liquid being drained. See TIS 7.318.
Sample Specification
A
Liquid drain traps shall be of the mechanical ball float type
having steel bodies, horizontal in-line connections, and stainless steel valve heads, seats and ball floats. Internals of the
trap shall be completely servicable without disturbing the piping.
A1
D
G
B
Installation
The trap must be fitted in a horizontal pipe line with direction of
flow as indicated and so that the float mechanism is free to rise
and fall in a vertical plane. Full-flow isolating valves should be
placed to permit servicing.
The high point of the body is provided with a 1/2” NPT tapping
for a balance pipe, which is essential for satisfactory operation of
this unit. The balance pipe must be connected with a continuous
rise between the tapping provided on the body of the trap and
the vessel being drained. The trap discharge should be piped to a
safe place.

Dimensions
(nominal) in inches and millimeters
Maintenance
This product can be maintained without disturbing the piping
connections. Complete isolation from both supply and return
line is required before any servicing is performed.
The trap should be disassembled periodically for inspection
and cleaning of the valve head and seat.
Worn or damaged parts should be replaced using a complete
valve mechanism kit.
Complete installation and maintenance instructions are
given in IMI 7.306, which accompanies the product.

The erosion deflector is pressed into the body during
manufacture and not available as a spare.
Liquid drain traps can be used to drain liquids from most gases.
However, some applications, particularly those involving hazardous or unusual fluids, may be subject to regulation or may otherwise
require special consideration.
Spirax Sarco will endeavor to provide whatever data is necessary to
