Description

The Armstrong International C3510-4 is a heavy-duty, high-pressure drain trap engineered for demanding steam and condensate management applications. Part of the Series 11LD line, this free floating lever drain trap is constructed from corrosion-resistant stainless steel, making it an ideal choice for aggressive process environments where durability and long service life are essential.

The free floating lever mechanism automatically expels condensate and non-condensable gases while preventing steam loss — delivering reliable, efficient drainage without the need for constant manual intervention. With a maximum allowable pressure of 400 PSI and a precision-machined 5/64″ orifice, this trap is designed to handle high-pressure steam systems with consistent, controlled discharge.
