The 3 port rotary shoe valve is used in heating and cooling systems to control and distribute
the operating medium. The 3 port rotary shoe valve can be used as a mixing valve or diverting
valve.

The 5Nm actuator is a compact design for operating rotary mixing valves and
diverting valves DN15/50. The motor is reversible with fixed limit switches for an
operating range of 90° and has manual override facility. Available in 230vAc or 24vAc.

The 15Nm actuators are for operating rotary mixing valves and diverting valves up to
DN150 with high torque ratings. Power supply can be either 230V AC or 24V AC to suit
all building management systems.

Motorised plug & seat valves for control of heating & cooling systems. Valves and actuators
are important products in heating, cooling and air-conditioning systems. They must operate
reliably in rapidly changing conditions.

MWA supply high-quality linear actuated valves. Our actuated valves are used in
applications for heating systems, cooling and domestic hot water. The plug and seat valve
have been developed based on market requirements to maximize on safe and accurate
regulation for problem-free operation. The valves have a design which makes them self
cleaning, resulting in long trouble free service life. 2 and 3 port control valves are available
in a wide range. This range of valves are very cost effective due to low service requirements
and a long service life. Valves are also available with pressure-balanced plug, allowing them
to be regulated with low thrust even with large pressure drops. The design of the valve plug
prevents particles in the medium from getting caught. It also offers excellent resistance to
erosion and corrosion damage. The plug is guided into the seat to prevent vibrations. The
patented design also helps minimise flow noise. The valve’s flow characteristic has been
modified by an equal percentage, providing good regulating control for the installation. This
gives a high level of precision even with small flow rates. The motorised plug & seat valves
can be used as a mixing valve or diverting valve.

Actuators for plug and seat valves are all self stroking (no need for limit switch
adjustment) for easy on site commissioning. Available in either 230v Ac, 24v Ac, 24vDc & 24vDc 0-10v.
