Spirax Sarco FTGS14HC-14/FTGS14HC-10/FTGS14HC-4.5 Float® Steam Trap Threaded/Flanged

The FTGS14HC is a Spirax Sarco float steam trap (1" threaded connection) with an austenitic stainless steel body, a built-in automatic air vent, and a nickel-plated ductile iron cover for good corrosion resistance, and in-line maintenance without piping disassembly.

Available Models

• FTGS14HC(R-L): Horizontal connection, flow direction right to left
• FTGS14HC(L-R): Horizontal connection, flow direction left to right

draw attention to sth.: Consult Spirax Sarco if a change of direction is required on site.

fluid sac

Featuring the BP99/32 liquid bladder, it can be used for superheated steam with a superheat of 150°C@0 barg, 50°C@32 bar g.

selectable

• In addition to an air vent, this model has a Steam Lock Relief (SLR) to prevent steam locking in the system, and is designated with the letter C. Please contact Spirax Sarco for further information.
• A 3" BSP or NPT threaded hole can be drilled in the top of the bonnet for mounting a counterbalance tube.
• A 3/" BSP or NPT threaded hole can be drilled in the bottom of the bonnet for mounting a bleeder valve.

engine displacement (volume of air fuel mixture drawn in during one cycle)

Discharge shown is based on condensate discharge at saturation temperature. During the startup phase, the condensate is cold and the thermostatic air vent is open to provide additional condensate discharge. The additional cold water displacement from the evacuation air valve at different pressure differentials is shown below:

∆P (bar)	0.5	1	2	3	4.5	7	10	14
1" (kg / h)	580	600	650	670	700	1000	1300	1600

Security information, installation and maintenance

For detailed information, refer to the Installation and Maintenance Guide (M-P145-20) supplied with the product.
draw attention to sth.: The FTGS14 must be installed in the same direction of fluid flow as indicated by the arrow on the valve body, ensuring that the float arm is positioned horizontally as well as ensuring that the float can rise and fall freely and vertically.
