Precautions
Installation location
The valve should be installed on the return pipeline, where the temperature is low and the sealing chamber load is also low
Pre valve filtration
Install a filter or dirt collector in front of the valve to ensure valve regulation function and long service life Remove dirt, welding slag, etc. from valves and pipelines
Qi turbidity
Limiting the pressure difference before and after the valve based on the relationship between medium temperature and pressure can prevent cavitation
flow direction
debug
The valve can only be debugged after the valve and actuator are correctly assembled
Ensure a reliable connection between the actuator push rod and the valve stem in all installation orientations
Open/close inspection
| valve | 直通A→AB | Bypass B → AB |
| Valve stem extended | Close | open |
| Valve stem retraction | open | Close |
maintenance
Valves do not require maintenance Before performing valve or actuator maintenance:
Stop the water pump and cut off the power supply
Close the shut-off valve
Release the pressure in the pipeline system and wait for the pipeline to cool down
If necessary, electrical wiring needs to be removed Due to the use of different types of materials, the valve must be disassembled before being scrapped According to legal regulations or ecological environment requirements, certain valve components require special treatment It is necessary to comply with the current local laws and regulations
guarantee
The technical parameters of the valve are only applicable to the use of the valve in conjunction with our company's electric actuator When using actuators from other manufacturers, the terms guaranteed by our company will become invalid
