Application scenarios
Condensate drainage from high-pressure steam heat exchangers
For condensate drainage from steam heat exchangers. The FTC62 is a float steam trap with a built-in automatic air vent. Selection should be based on the maximum differential pressure of the specific model and the pressure and temperature limits applicable to the selected connection type.
Condensate drainage from steam heating equipment under varying load conditions
For condensate drainage from steam heating equipment in steam heating systems with temperature control and changing operating conditions. The valve cover can optionally be drilled for installation of a balancing pipe; this option must be specified when ordering.
Condensate drainage from steam jackets or tracing lines
For condensate drainage from steam jackets or steam tracing lines. The FTC62 is available with DN15 to DN25 connection sizes and threaded, socket weld, and flanged connections. The selection must meet the applicable pressure, temperature, and model differential pressure limits for the selected connection type.
Selection points
High operating differential pressure and saturated steam pressure ratings
The maximum operating differential pressures of FTC62-46 and FTC62-62 are 46 bar and 62 bar, respectively. For threaded and socket-weld connections, the maximum saturated steam operating pressure is 80 bar g, making the traps suitable for high-pressure steam condensate drainage applications within the corresponding differential pressure ranges.
Carbon steel body with stainless steel internals
The body is made of carbon steel complying with EN 10213 1.0619+N or ASTM A216 WCB, while the internal components are made of stainless steel.
Built-in bimetallic automatic air vent
The product features a built-in bimetallic automatic air vent with a closing temperature of 120 °C to 135 °C.
Multiple connection standards and bidirectional flow configurations
The product is available with BSP or NPT threaded connections, socket-weld connections complying with BS 3799 Class 3000 lbs, and flanged connections complying with EN 1092-1 PN100 or ASME B16.5 Class 600. L-R or R-L flow direction can be selected.
Optional tapping for balance pipe installation
The cover can be drilled as required for balance pipe installation. This option must be specified when placing the order.
Installation & maintenance notes
Install according to the selected flow direction
During installation, confirm that the valve's selected flow direction matches the flow direction of the site piping. FTC62 is available in L-R (left-to-right) and R-L (right-to-left) flow versions.
Verify pressure, temperature, and operating differential pressure for the selected connection type
Before installation, verify that the system pressure and temperature do not exceed the applicable limits for the actual connection type, and confirm that the maximum operating differential pressure does not exceed the limit of the selected model: 46 bar for FTC62-46 and 62 bar for FTC62-62.
FAQ
How does the FTC62 float steam trap work?
The FTC62 uses a carbon steel body, built-in stainless steel trim, and an air vent mechanism. The float linkage moves up and down to control valve opening and closing, separating and discharging steam and condensate.
What flow direction options are available for the valve?
When facing the valve body, the flow direction can be selected as L-R (left to right) or R-L (right to left) to match the installation flow direction of different systems.
Which parameters can be affected by the configuration selected when ordering?
Options include the ability to drill the valve cover for installation of a balancing pipe, which must be specified when ordering. This configuration is a special product option and may incur additional charges.
What certification and compliance information is available for this product?
The product complies with the EU Pressure Equipment Directive 2014/68/EU and carries the CE marking. An EN 10204 3.1 certificate can also be provided when ordering.
What size and connection options are available?
Available sizes include 1/2, 3/4, and 1 inch. Connection options include threaded connections (BSP/NPT), socket weld connections, and flanges complying with standards such as EN 1092-1 PN100 and ASME B16.5 Class 600. The specific selection should be confirmed based on the actual operating conditions.
