Manufacturers of the Highest Quality:Control Valves for ElevatorsTank Heaters - Hand PumpsPipe Rupture Valves - Ball Valves

KV 1/2" solenoid valves are designed for small hydraulic lifts operating at speeds up to 0.16 m/s (32 fpm) or 1 m/s (200 fpm)depending on the valve selected. The smooth and accurate ride characteristics of the KVH valve which includes 'soft stop' inboth directions, render it highly suitable for quality home lifts and lifts for the handicapped.

Adjustments UP

1. Up Bypass: When the pump is started, the unloaded car should remain stationary at the floor for a period of about 1 secondbefore 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. Noadjustment possible.

S Relief Valve: 'In' (clockwise) produces a higher, 'out' (c-clockwise) a lower maximum pressure setting (3 mm Allan Key).


5. Up Stop: At floor level solenoid A is de-energized. Through a time relay the pump must run approx. 1/2 seconds longer to allowthe car to stop smoothly by valve operation according to the setting of adjustment 5. 'In' (clockwise) provides a softer stop, 'out'(c-clockwise) a quicker stop. Pre-adjustment: With solenoid A disconnected and the pump running, 5 should be turned in until thecar starts to move up, then slowly backed off again until the car stops.

Alternative Up Stop: At relatively higher speeds and with the time relay arrangements as with 'up stop' above, the car maytravel to just above floor level. In overtravelling the floor, down leveling solenoid D is energized, lowering the car smoothly backdown to floor level where D is de-energized.



Up Stop: At floor level, the pump-motor is de-energized. The stop may be abrupt depending on load and speed of approach. Noadjustment possible.



5. Up Stop: At floor level solenoid A is de-energized. Through a time relay the pump must run approx. 1/2 seconds longer to allowthe car to stop smoothly by valve operation according to the setting of adjustment 5. 'In'' (clockwise) provides a softer stop, 'out'(c-clockwise) a quicker stop. Pre-adjustment: With solenoid A disconnected and the pump running, 5 should be turned in until thecar starts to move up, then slowly backed off again until the car stops.

Alternative Up Stop: At relatively higher speeds and with the time relay arrangements as with 'up stop' above, the car maytravel to just above floor level. In overtravelling the floor, down leveling solenoid D is energized, lowering the car smoothly backdown to floor level where D is de-energized.



3. Deceleration: When C is de-energized, the car decelerates according to adjustment 3 to leveling speed. 'In' (clockwise) providesa softer, 'out' (c-clockwise) a rougher deceleration.

4. Up Leveling: With solenoid C de-energized (see 3) the car will proceed at its leveling speed according to the setting of adjustment4. 'In' (clockwise) provides a quicker, 'out' (c-clockwise) a slower leveling speed.

3. Up Stop: At floor level solenoid A is de-energized. Through a time relay the pump must run approx. 1/2 seconds longer to allowthe car to stop smoothly by valve operation according to the setting of adjustment 3. 'In' (clockwise) provides a softer stop, 'out'(c-clockwise) a quicker stop. Pre-adjustment: With solenoid A disconnected and the pump running, 3 should be turned in until thecar starts to move up, then slowly backed off again until the car stops.


Nominal Settings: Adjustment 1 (and 4 at KVH) level with flange faces. Adjustment 3 (at KVH) all the way 'in' (clockwise) then threeturns 'out' (c-clockwise). Adjustment 5 (KV1 & KV2) level with flange faces.

Valves are already tested and adjusted. Check electrical operation before changing valve settings. Test that the correct solenoid isenergized by removing nut and raising solenoid slightly to feel pull.

KV1P / KV1S6. Down Acceleration: When solenoid 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: 6 should be turnedall the way in and then solenoid D energized. Turn 6 slowly back out until the car accelerates downwards.

7. Down Speed: With solenoid 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 floor level, solenoid 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.

KV2P / KV2S / KVH6. Down Acceleration: When solenoids C and D are 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: 6should be turned all the way in and then solenoid C and D energized. Turn 6 slowly back out until the car accelerates downwards.

7. Down Speed: With solenoids C and D energized as above, the down speed of the car is according to the setting of adjustment7. 'In' (clockwise) provides a slower down speed, 'out' (c-clockwise) a faster down speed.

Down deceleration: When solenoid C is de-energized whilst solenoid D remains energized, the car will decelerate according to thebuilt-in damping. No further adjustment will be required.

9. Down Leveling: With solenoid C de-energized and solenoid D remaining energized, the car will travel at its down leveling speedaccording to the setting of adjustment 9. 'In' (clockwise) provides a slower, 'out' (c-clockwise) a faster down leveling speed.

Down Stop: At floor level, solenoid 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.

KS Slack Rope Valve Nominal Settings: With the end of adjustment K initially level with flange faces, open the manual lowering.Thecar without load should descend. Turn 'in' (clockwise) adjustment K until the car comes to a stop then 'out' (c-clockwise) againuntil it again descends. In case the car does not come to a stop, i.e. at pressures over 15 bar, turn 'in' (clockwise) K all the way andthen back 'out' (c-clockwise) half a turn. See also KS sheet.

Valves are already tested and adjusted. Check electrical operation before changing valves settings. Test that the correct solenoidis energized by removing nut and raising solenoid slightly to feel pull.

KV Nominal Settings: Adjustments 7 & 9, screwheads level with the hexagon heads.
