Intellectual Property Rights Explanation：
Warning:
The symbol means the unit is being installed,
it may cause electrical shock hazard during
maintaining, so please make sure it is operated
by the professional technical worker.
1. Summarize
CKF series of Electrical Valve is good at on the on-off conversion
controlling of Heating Air Condition Water System, be consist of a
driver and a valve body .The driver adopts the synchronous motor
drive, spacing-contactor inside, can make the valve complete
Power-on or complete power-off. Valve body is plated with rustproof
brass, and its surface also be spray the sand and phosphated.
Provided with the manual switch, be very convenient to alive
adjustment or press adjustment, it will recover automatically when
the power is on.
2 Technique Requirements.
Driver Voltage: AC230V+/-10%,50/60Hz (Special made 110V or 24V)
Power Consume:4VA(only when the valve is open)
Running Time: Power on -18 sec. Powe off-15sec.
Length of Down-lead:100cm
Normal Pressure:1.6MPa
Closed Pressure differential: 2-way 0.3MPa; 3-way 0.15MPa
Connected mode: tube screw thread G
(Can not be connected with taper screw thread)
Medium of application: cold and frozen water, hot water and t
50% etylene glycol.
Temperature of Medium:2-75 ℃

Rustproof brass valve body with high intensity, the pressure is big during its
installing.
2 Low Power Consume, it only takes 4w power when the valve is open or closed.
3 Provided with spacing-contactor inside in order to make sure the long using life
of motor.
4 Open the valve for 50 by manual, after debugging press-testing, it will auto-
replace when it is gave the power.
5 The driver can be unloaded and connected expeditiously, simple to manipulate.
6 Valve is made uniquely, make sure it is closed intensively

1 Before the installation, pls make sure the cleaness of pipeline, no
sundries allowed
2 The valve can follow the flow way of A to B (2-way);A to AB or B to AB.
It also can be connected to pipeline in any corner, but do not make driver lower
than the horizontal line of valve. Also make sure that there has enough space
around the driver in order to doing the maintenance and exchanging.
3 The screw thread which connected with the valve must be screw thread G, do not
use the taper screw thread. Attention: The driver can be installed vertically on
the valve, at this set, the lock pin will not play the role of lockup

9 Order notice and Installed Requirements.
4 When screwing the part which water tube connected, do not fasten the
driver, but handhold the valve and make spanner connected on the hexangular
nut or hexangular valve`s body. When installing the compact valve, lockup nut
tightly to prevent it to make water. Attention, don't screw it excessively, its max
torque is restricted from 44N.m 60N.m.
5 Pls make sure the heat preservation of pipeline and valve, do not put
actuator to the attemperator`s inner side.

9.1 Before your send your goods order, pls provide below parameter:
Product Model, Normal way-dimension,Normal Pressure; Flux
Coefficient m /h; Medium Variety and Working Temperature.
9.2 When the valve and actuator are provided separately, we can
assemble them in spot.
