Application scenarios
Condensate discharge from steam-heated heat exchangers
Installed at the condensate outlet of a steam-heated heat exchanger for continuous discharge of condensate generated as the load changes. The built-in thermostatic air vent discharges air during start-up, helping the heat exchanger establish normal heat transfer conditions more quickly.
Condensate drainage from steam-heated equipment in corrosive environments
Used in condensate drainage branches for steam-heated equipment where there is a risk of corrosion. The austenitic stainless steel body provides good corrosion resistance, making it suitable for drainage points where corrosion resistance is required.
Selection points
Stainless steel body material
The body is made of austenitic stainless steel EN 10213-4(1.4308) or ASTM A351 CF8, providing a selection criterion for applications where body material is a key consideration.
Built-in thermostatic air vent
The product is equipped with a BP99/32 balanced pressure thermostatic air vent, providing a selection criterion for steam trap applications requiring automatic air venting.
Optional steam lock release device
An optional steam lock release device is available. Models with this option have C appended to the order code, providing an option for applications where steam lock is a potential risk.
Horizontal bidirectional flow and multiple maximum differential pressure options
The product is available with two horizontal connection flow directions, R-L and L-R, and with maximum differential pressure versions of 4.5bar, 10bar and 14bar. The selected model must match the actual pipe flow direction and differential pressure.
Installation & maintenance notes
Match the model to the horizontal connection direction and flow
FTGS14HC is available only with horizontal connections. The flow direction of FTGS14HC(R-L) is from right to left, while that of FTGS14HC(L-R) is from left to right. Before installation, verify that the selected model matches the flow direction of the site piping. Consult Spirax Sarco if the direction needs to be changed on site.
FAQ
How does the FTGS14HC work, and how does the float steam trap achieve discharge and pressure control?
The FTGS14HC monitors the water level through its built-in float mechanism. As condensate rises in the steam pipeline and lifts the float, the valve opens automatically to discharge steam and condensate, maintaining system safety and efficiency.
What are the key selection criteria for this valve, and how should the appropriate size and connection type be determined?
The valve has a 1-inch port with BSP or NPT threaded connections. Models are available with R-L (right-to-left) and L-R (left-to-right) flow directions. Selection should be based on the system piping direction and site layout. The specific configuration must be confirmed according to the actual model and application conditions.
Does this model include an air vent, and is a steam-lock breaker available as an option?
The standard model includes an air vent. An FTGS14HC-C version with an optional steam-lock breaker (SLR) is also available. Specify the requirement when ordering.
How do the material and temperature ratings affect corrosion resistance, and is the valve suitable for high-temperature, highly corrosive environments?
The body is made of austenitic stainless steel, and the cover is nickel-plated ductile iron, providing good corrosion resistance. The maximum operating temperature, differential pressure, and other limits must be determined according to the parameters of the specific model and must not be exceeded. The specific configuration must be confirmed according to the actual model and application conditions.
What are the key installation and maintenance considerations, and how can in-line maintenance be ensured?
Ensure that the flow direction indicated by the arrow on the body is correct, and that the float arm is horizontal and can move freely in the vertical direction. Consult the supplier if the flow direction needs to be changed on site. The product supports in-line maintenance, with detailed procedures provided in the installation and maintenance guide supplied with the product. The specific configuration must be confirmed according to the actual model and application conditions.
