What is the difference between FTS14, FTS14X, and FTS14-C models?

The base FTS14 is the standard ball float trap. The FTS14X includes an internal strainer screen for protection against debris. The FTS14-C adds a manually adjustable needle valve for steam lock release, useful in applications prone to steam locking due to long condensate lines or sub-cooled condensate.

Can the FTS14 be installed in vertical pipelines?

Yes. The FTS14 cover can be rotated to allow vertical up or vertical down installations in addition to standard horizontal configurations. No additional parts are required.

What spare parts are available for the FTS14?

Spirax Sarco offers a complete maintenance kit containing the main valve seat, gaskets, ball float and lever, air vent assembly, pivot frame, and other internals. A gasket-only set is also available. Always specify the size and pressure rating (4.5, 10, or 14 bar) when ordering spares.

Is the FTS14 suitable for hygienic or sanitary steam systems?

Yes. The FTS14-4.5 model is available with Tri-clamp end connections for hygienic and sanitary applications. The O-ring material is FDA CFR Title 21 compliant.

What is the condensate capacity of the FTS14 at start-up?

During start-up, the thermostatic air vent opens and provides additional condensate capacity beyond the main valve. On 4.5 bar units, this provides a minimum 50% increase; on 10 and 14 bar units, capacity increases by at least 100% above published hot condensate figures.

Overview

The Spirax Sarco FTS14 is an austenitic stainless steel ball float steam trap designed for efficient condensate drainage and prompt air removal in process steam applications. The integral automatic air vent ensures that process equipment operates at maximum thermal efficiency by eliminating air and non-condensable gases from the steam system.

A key advantage of the FTS14 is its configurable design — the cover can be rotated to allow horizontal (right-to-left or left-to-right), vertical up, or vertical down installation configurations without additional components. This flexibility simplifies installation across varied piping layouts commonly found in Indian manufacturing plants.

The FTS14 is constructed entirely from 316 stainless steel (EN 10213-4 / ASTM A351 CF8M), making it suitable for corrosive environments, hygienic applications, and high-purity steam systems. It is available with optional internal strainer (FTS14X) and a manually adjustable needle valve for steam lock release (FTS14-C).
