Description
Spirax Sarco FTC32 (DN15 and DN20) carbon steel float steam trap with an internal automatic air vent is an ideal choice for efficiently removing condensate in process applications with fluctuating pressure and load conditions. The standard connection is horizontal, right-to-left flow when viewed from the bottom of the valve.
