Single coil / solenoid valve
Up movement in KV1-P lift valve
One up speed, 0.16 m/s (32 fpm) max.
Up start has built-in damping.
Up stop has no damping (pump stops).
For the correct installation and safety of the lift, the correct installation of the solenoid valve, which is one of its components, is very important, and negligence in this regard can lead to irreparable accidents and loss of life and property. And it should be according to the principles and content of the guide. The following are the up and down movement settings of the elevator and the control elements and adjustment parameters of the single-valve Tork hydraulic valve.
One up speed, 0.16 m/s (32 fpm) max.
Up start has built-in damping.
Up stop has no damping (pump stops).
One down speed, 0.16 m/s (32 fpm) max.
Down start has adjustable damping.
Down speed is adjustable.
Down stop has built-in damping.

Warning
Only qualified personnel should adjust or service valves. Unauthorised manipulation may result in injury, loss of life or damage to equipment. Prior to servicing internal parts, ensure that the electrical power is switched off, cylinder line is closed and residual pressure in the valve is reduced to zero.
Valves are already adjusted and tested. Check electrical operation before changing valve settings.
Test that the correct coil is energized, by removing the nut and raising the coil slighty to feel pull.
When the pump is started, the unloaded car should remain stationary at the floor for a period of about 1 second before starting upwards. The length of this delay is according to the setting of adjustment 1. 'In' (clockwise) shortens the delay, 'out' (c-clockwise) lengthens the delay.
Up Stop:At floor level, the pump-motor is de-energized. The stop may be abrupt depending on load and speed of approach. No adjustment possible
S Relief Valve:'In' (clockwise) produces a higher, 'out' (c-clockwise) a lower maximum pressure setting. After turning 'out', open manual lowering H for an instant. Important: When testing relief valve, close ball valve gradually.
WarningValves are already tested and adjusted. Check electrical operation before changing valves settings. Test that the correct coil is energized by removing nut and raising the coil slightly to feel pull.
When coil D is energized, the car will accelerate downwards according to the setting of adjustment 6. 'In' (clockwise) provides a softer down acceleration, 'out' (c-clockwise) a quicker acceleration. Pre-adjustment: Turn adj. 6 all the way in and then energize coil D. Turn 6 slowly back out until the car accelerates downwards.
9. Down Speed:With coil D energized as above, the down speed of the car is according to the setting of adjustment 9. 'In' (clockwise) provides a slower down speed, 'out' (c-clockwise) a faster down speed.
Down Stop:At fl oor level, coil D is de-energized causing the car to stop. No adjustment necessary.
H Manual Lowering:'out' (c-clockwise) allows the car to be lowered by hand. Closes automatically on release.
Important:
Length of ½" thread on pipe connections should not be longer than 14 mm!
For pressure-flow condition within shaded area, use ¾" piping to avoid unnecessary pressure loss. Pump flows above 80 l/min are not recommended.
