HX are manually operated down valves, adjustable in their down speed. They close automatically upon release. They can be used for emergency manual lowering or in combination with the EV down valve to achieve an overspeed of the elevator for testing the pipe rupture valve.

MX are solenoid operated down valves, adjustable in their acceleration, down speed and deceleration. They can be used for the revision or inspection travel of the elevator or as a particularly slow down speed valve in addition to the two down speeds of the EV valve to obtain extremely exact floor stops.
