Double Speed Buffer-type Triple Valve (JL36-5)

 Ascend 

The elevator ascends with a motor that directly drives the oil pump,  eliminating the need for a frequency converter.  Acceleration and deceleration are controlled by pilot valve coil A via  the throttle valve.

• After the motor starts, coil A is energized, and the elevator  accelerates smoothly to the set operating speed.  

• When the preset deceleration position is reached, coil A is  de-energized, and the elevator decelerates.  

• Upon arriving at the leveling position, the motor stops, and the  elevator comes to a slow stop.

Descend

For descent, the elevator uses dual solenoid valves to control the  fast and slow pilot throttle valves for speed regulation.  Upon receiving the descent signal, both the fast and slow solenoid  coils are energized, opening the two pilot throttle valves, and the  elevator begins a smooth, accelerated descent. When it reaches  the preset deceleration position, the fast solenoid coil  de-energizes, causing the fast pilot throttle valve to close gradually,  and the elevator decelerates to a slow speed. Upon reaching the  leveling position, the slow solenoid coil de-energizes, the slow pilot  throttle valve closes, and the elevator stops accurately
