Description

FTGS14HC is a Spirax Sarco float and thermostatic steam trap with a 1” threaded connection. The body is made of austenitic stainless steel and includes an automatic air vent. The cover is nickel-plated spheroidal graphite cast iron, providing good corrosion resistance. The trap can be maintained online without dismantling the piping.

Available Models

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

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

Note: Consult Spirax Sarco if the flow direction needs to be changed on site.

Capsule

The BP99/32 capsule can be used with superheated steam, with a superheat limit of 150°C@0 barg and 50°C@32 bar g.

Options

  • In addition to the air vent, this trap can be fitted with a steam-lock release device (SLR) to prevent steam locking in the system. Models with this option have the letter C added to the model designation. Contact Spirax Sarco for further information.

  • A 3”BSP or NPT threaded hole can be drilled in the top of the cover for installation of a balance pipe.

  • A 3/”BSP or NPT threaded hole can be drilled in the bottom of the cover for installation of a drain valve.

Standards and Certificates

  • This product complies with the European Pressure Equipment Directive 97/23/EC.

  • A typical manufacturer’s test report can be supplied with the product. If a certificate is required, specify this when placing the order.

Capacity

The capacity shown in the chart is the condensate capacity at saturation temperature. During startup, the condensate is cold and the thermostatic air vent is open, providing additional condensate capacity. The additional cold-water capacity provided by the air vent at different differential pressures is shown below:

Safety Information, Installation and Maintenance

For detailed information, refer to the installation and maintenance instructions supplied with the product (M-P145-20).

Note: FTGS14 installation must match the fluid flow direction indicated by the arrow on the body. Ensure that the float arm is horizontal and that the float can move freely in the vertical direction.

Disposal

This product is recyclable and will not cause environmental problems when disposed of properly.
