All-Stainless Steel Material
Description
The TD32F is a maintainable medium pressure flanged thermodynamic steam trap which has an integral strainer screen fitted to protect the internals from dirt.
- TD32FLC: Designed specifically for low load applications such as steam mains drainage.
- TD32FA / TD32FALC: Fitted with an anti-air-binding disc to ensure prompt removal of air on start-up.
- TD32FALC: Identified by the groove in the cap.

Capacities
Installation and Maintenance
The TD32F is designed for installation with the disc in a horizontal plane with the cover at the top.
- It is recommended that a non-return valve is fitted when discharging condensate into return lines where backpressure is experienced.
- It is also recommended that a diffuser is fitted when discharging to atmosphere.
- For ease of maintenance, fit isolation valves upstream and downstream of the steam trap.
- For full details see the Installation and Maintenance Instructions (IM-P068-26) supplied with the product.
