Door opening systems
Our pioneering pneumatic control door-opening
system for buses and coaches offers:
> A complete, customised system built from three
basic components: emergency valves, door-
opening block and pneumatic cylinders
> Integrated safety functions, including a
manual override option and an automatic
reverse function for obstacle detection
Climate control valves
Our high performance climate control valves offer
motorised proportional and digital control of engine
coolant, enhancing temperature control for passengers
in buses and coaches. Features include:
> Digital control - damped closing reduces pressure shock
to the coolant system and puts less strain on the radiator
> Motorised proportional valve delivers constant flow and
reduces pressure shock on the radiator, while power
consumption closes off when a set point is reached
> Ceramic discs are resistant to dirt and variation of
temperature, ensuring a more reliable performance
> Motor drive for flap control – EMV resistant and built to
high IP classification (IP6K9K), it includes a gold plated
pin contact to deliver high torque with minimal back lash
> Coolant control valves for the temperature
control of hybrid battery packs.
