Bronze Motorised Fixed Orifice Double Regulating Valve<br />
(Motorised FODRV)<br />
FEATURES AND BENEFITS<br />
• Provides precise and accurate flow regulation<br />
• Designed for circuits where combined<br />
functions of actuated regulation and flow<br />
measurement are required<br />
• Operated by motorised actuator<br />
• Integral fixed orifice commissioning valve and<br />
two port control panel – faster commissioning<br />
