KV
Elevator Control Valves
EN ISO 9001
KV ½" solenoid valves are designed for small hydraulic lifts operating at speeds up to 0.16 m/s (32 fpm) depending on the valve
selected. The smooth and accurate ride characteristics of the KV2S valve which includes 'soft stop' in both directions, render it
highly suitable for quality home lifts and lifts for the handicapped.

Warning: Only qualified personell 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.
Adjustments UP
Valves are already adjusted and tested. Check electrical operation before changing valve settings.
Test that the correct solenoid is energised, by removing the nut and raising the solenoid slighty to feel pull.
Nominal Settings: Adjustment 1 level with flange faces. Adjustment 5 (KV1S & KV2S) level with flange faces.
KV1P
1. Up Bypass: 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.
KV1S
1. Up Bypass: 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.
5. Up Stop: At floor level solenoid A is de-energized. Through a time relay the pump must run approx. 1 seconds longer
to allow the 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 the car 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
may travel to just above floor level. In overtravelling the floor, down levelling solenoid D is energized, lowering the
car smoothly back down to floor level where D is de-energized.
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.
KV2P

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.

KV2S
1. Up Bypass: 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.
5. Up Stop: At floor level solenoid A is de-energized. Through a time relay the pump must run approx. 1 seconds longer
to allow the 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 the car 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
may travel to just above floor level. In overtravelling the floor, down levelling solenoid D is energized, lowering the
car smoothly back down to floor level where D is de-energized.
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.

Warning: Only qualified personell 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.
Adjustments DOWN
Valves are already tested and adjusted. Check electrical operation before changing valves settings. Test that the correct solenoid is
energized by removing nut and raising solenoid slightly to feel pull.
KV Nominal Settings: Adjustments 7 & 9, screwheads level with the hexagon heads.
KV1P / KV1S
6. 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 turned
all the way in and then solenoid D energized. Turn 6 slowly back out until the car accelerates downwards.
9. 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
6. 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: 6
should 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 adjustment 7.
'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 the
built-in damping. No further adjustment will be required.
9. Down Levelling: With solenoid C de-energized and solenoid D remaining energized, the car will travel at its down levelling speed
according to the setting of adjustment 9. 'In' (clockwise) provides a slower, 'out' (c-clockwise) a faster down levelling 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: Solenoid D must be de-energised! The KS, is adjusted with a 3 mm Allan Key by turning the screw K 'in' for
higher pressure and 'out' for lower pressure. With K turned all the way 'in', then half a turn back out, the unloaded car should descend
when Manual Lowering H is opened. Should the car not descend, K must be backed off until the car just begins to descend, then
backed off a further half turn to ensure that with cold oil, the car can be lowered as required.
