1. Product overview
CKV6...A series of three-wire and two-wire electric ball valves are suitable for on-off control of HVAC water systems, water
systems, gas systems, etc., and are composed of two parts: a drive and a valve body.The drive motor (actuator) can be driven by
AC220V, 110V, 24V, and 12V AC synchronous forward and reverse motors, and DC24V, 12V, and 5V DC motors can also be used in water systems or natural gas systems.Built-in limit contacts can power off when the valve is fully open or fully closed.The valve body is all-copper forged, and the surface is pickled and passivated. After the actuator is removed, the valve can be manually opened and closed to facilitate on-site commissioning or pressure test operation.
2. Main technical parameters
Drive power supply: AC220V/110V/24V or DC5V/12V/24V±10%, 50/60Hz.
Power consumption: AC6.5VA or DC2.5VA (only when the wide door is opened and closed).
Motor category: AC forward and reverse synchronous motor or DC motor.
Action time: The AC motor is turned on for 15s and turned off for 15s.The DC motor is turned on for 32s and turned off for 32s.
Lead length: 550-2000MM (customizable).
The nominal pressure of the valve body: 1.6 or 2.5MPa.
Connection method: pipe thread G inner, outer wire or live connection, PPR\PERT snap connection.
Applicable medium: frozen water, hot water or low-pressure steam.
Medium temperature: 1-85ºC.
Valve body, sphere, stem material: copper 57-3 or 59-1.

6. Handling of abnormal problems
| Serial number |
Abnormal phenomenon |
Possible cause of failure |
Troubleshooting method |
| 1 |
The position of opening the valve is opposite to closing the valve |
Wiring error |
Change the valve opening line and the valve closing line |
| 2 |
Leakage at the threaded connection |
The connection is slightly cracked, the installation is not standardized or the force is too large |
Replace the valve body |
| 3 |
The actuator does not operate |
Wiring error, line falling off |
Check the power supply and line thermostat |
| Valve body, thermostat intact, actuator abnormal |
Replace the actuator |
| 4 |
The valve cannot be fully opened or fully closed |
Pipe debris is clogged or the water quality is too poor |
Clean up pipeline debris or install a pre-filter, or replace the valve body |
| 5 |
Abnormal noise continuously occurs in the drive |
Damaged motor |
Replace the drive |
| Dirty valve body |
Replace the valve body |
