Advantages of motor actuated ball valves of
EMV110..series with incorporated relay module for
solar heating systems
In solar heating systems motor actuated ball valves can prevent
various inconveniences.
• Effectively prevent hydraulic shocks in systems as they require 30 seconds for
complete opening.
• Due to their shape they do not impede the flow.
• Springs are not included, therefore noise does not appear.
• When closed, 100% sealing is guaranteed.
• They have an output for pump up to 100 W in open position, therefore they do not present
a hydraulic load for pump in closed position. They enable pump switching on only in
completely open position.
• Due to installed RELAY module they enable control with make contact only.
• If during closing or opening process impurities enter in valve, which could block it, the
valve stops and immediately afterwards continues with opening or closing process in
opposite direction, so that water flow can rinse the impurities up to cleaning net (anti-
blocking system).
