NORMALLY OPEN SERVO ASSISTED SOLENOID VALVES
MWA range of servo assisted solenoid valves are suitable for water, air and oil at temperatures of -10 °C to +120 °C.
The servo assisted solenoid valve has a far higher pressure rating as it uses the differential pressure across the solenoid
valve to help it to close with the solenoid operator. There must be a difference of 0.1 bar from the up stream and
down stream pressures across the solenoid valve.
NORMALLY CLOSED DIRECT ACTING SOLENOID VALVES
MWA range of direct acting solenoid valves are suitable for water, air and oil at temperatures of -10 °C to +160 °C.
The direct acting solenoid valve is ideal for smaller pipe sizes where there is no pressure differential across the solenoid
valve. This means that the solenoid valve will operate if there is equal pressure on the up stream and down stream of
the solenoid valve.
NORMALLY CLOSED SERVO ASSISTED SOLENOID VALVES
MWA range of servo assisted solenoid valves are suitable for water, air and oil at temperatures of -10 °C to +120 °C.
The servo assisted solenoid valve has a far higher pressure rating as it uses the differential pressure across the solenoid
valve to help it to open with the solenoid operator. There must be a difference of 0.5 bar from the up stream and
down stream pressures across the solenoid valve.

VALVES
ROTARY SHOE VALVE - 3 port valve for mixing and diverting
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.
lThe bsp female threaded valve is available DN20/50.
lThe PN6 anged valve is available DN20/150.
ACTUATORS FOR ROTARY SHOE VALVE
The 5Nm actuator is a compact design for operating rotary mixing valves and diverting valves DN15/50. The
motor is reversible with xed limit switches for an operating range of 90 °C 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.
PLUG AND SEAT VALVES FOR MIXING & DELIVERING
Motorised plug & seat valves for control of heating and cooling systems. Valves and actuators
are important products in heating, cooling and air-conditioning systems. They must operate
reliably in rapidly changing conditions.
MWA Technology 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 a long trouble free service life. 2 and 3 port control valves are available in
a wide range, which are very cost effective due to low service requirements and a long service
life. Valves are also available with a 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 ow noise. The valve’s ow characteristic has been modied by an equal percentage,
providing good regulating control for the installation. This gives a high level of precision even
with small ow rates. The motorised plug and seat valves can be used as a mixing valve or
diverting valve.
ACTUATORS FOR PLUG AND SEAT VALVES
MWA Technology 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, 24V DC & 24V DC 0-10V.
