<p>The zone valve for a hydronic system has a device (10-12) for coupling the actuator (4) to the valve body (2) by way of an intermediate support platform (12), the actuator (4) being removable from the valve body. The coupling device (10-12) comprises a mounting bracket (10) resting on said support platform (12), a base plate (11) for supporting the motor (5) and the drive mechanisms (9,21-25), which has two retaining elastic tabs (14,15) for securing the actuator (4) to the support platform (12). The base plate (11) is a plastic moulding fastened onto the mounting bracket (10), further incorporating a tubular guide (21) for the valve spindle (8) while at the same time supporting the torsion spring (22), a strip-spring (23) built into a vertical wall reacting with a manual locking lever (25) for the motor (5).</p> |
