ASSA ABLOY DC340 Door Closer EN 1-4 Black EN 1154 Thermodynamic Valve 80kg

Product Overview

The Assa-Abloy DC340 door closer (body only, without arm) is designed for use on fire-rated, smoke-control, and standard doors, supporting leaf weights up to 80 kg and widths up to 1100 mm when used with a sliding rail. It is certified to EN 1154, making it suitable for use in compliance-driven commercial, institutional, and residential building projects that require fire safety hardware. The closer is compatible with both left and right-handed doors and enables installation either on the door leaf (hinge side) or on the frame (opposite hinge side).

A standout feature of the DC340 is its thermodynamic valve technology, which ensures stable closing performance despite temperature fluctuations. This eliminates procurement risks related to variable climate conditions and helps installers meet performance specifications in unheated or temperature-variable environments. Especially suited for fire-protection retrofit projects and commercial installations seeking EN 1154 compliance without risk of temperature-induced malfunction.
