ABB VA/Z78.1 Valve Adapter for Danfoss RA

Description

Introduction

The ABB VA/Z78.1 Valve Adapter is an essential mounting accessory designed for HVAC and heating control installations using thermostatic valve bodies. It enables secure snap-on mounting of compatible ABB Thermoelectric Valve Drives—specifically models TSA/K 230.2 and TSA/K 24.2—onto specified valve bases or within heating circuit distributors. By ensuring a precise mechanical interface, this adapter facilitates reliable valve drive operation across commercial and residential climate control systems. This device is part of our KNX Actuators products range.

Given the limited technical specification footprint for mechanical accessories, strict verification against your project’s Bill of Quantities (BOQ) and valve body specifications is crucial. Purchasing managers and system integrators should confirm exact valve model compatibility prior to procurement to prevent mismatched hardware on site and avoid installation delays.
