Series VDS valves are particularly suitable to systems with flow rates. VDS valves are supplied with a cap, that protects the thread from damages and allows the complete closure of the valve during system start-up.
The thermostatic insert can be inspected and, if necessary, the spindle o-ring can be replaced even while the system is working. VDS device can be mounted either as a straight or an angle valve according to requirements, simply by screwing the plug (also supplied) into the unused inlet.
In the motorised version, VDS 02, the obturator is machined so to provide a better adjustment, and the headwork has been designed to allow the direct installation of the servomotor on the valve: this ensures a 1-mm extra-stroke from closure position and a higher tolerance on the motor stroke.
