The motorised valve is probably the hardest working component in
'wet' domestic central heating systems. Sunvic Controls' Motor
On/Motor Off (MoMo) valves only operate when the valve changes
position, resulting in greater reliability and longer life.
Independent testing has shown the MoMo to be 96% more energy
efficient than similar spring return versions. The homeowner saves
on electricity and enjoys a longer component life as wear and tear
on the valve and actuator components (such as the synchronous
motor) are reduced during longer 'Off' periods.
Patented 'slipseal' technology provides a tight valve shut-off
and enables improved flow rates, reduced pressure losses and less
turbulence within the valve chamber. This unique 'slipseal' feature
is self-cleaning, further enhancing the life of the product.
The 2-port MoMo and 3-port MoMo both use simple industry
standard wiring. They are easy to install and can readily replace
almost all domestic spring return valves making them suitable for
both new-build and refurbishment/upgrade applications. All MoMo
valves have a valve position indicator and a robust manual
thumbwheel to simplify commissioning.
Industry-standard valve body dimensions mean minimal, if any,
pipework changes. No changeover thermostats or special relays are
required. Additionally, valve actuator replacement does not require
If energy efficiency and high reliability are important in your
application, consider Sunvic Controls' MoMo products. The MoMo
range was designed and is fully manufactured in theUK.
