Frequently Asked Questions
What body and trim materials are used in these butterfly valves?
The series incorporates a blue epoxy coated ductile iron body, paired with an EPDM seat and a disc made either from stainless steel (CF8 / CF8M) or blue epoxy coated ductile iron.
What are the maximum pressure and temperature limits?
These valves are engineered to withstand a maximum working pressure of 16.0 Bar and a maximum operating temperature of 85°C.
What operation options are available across the size range?
Valves ranging from DN40 to DN300 support lever and gear operation. Larger sizes from DN350 to DN600 and beyond are operated by a manual gearbox.
What are the differences between 4020 and 4325 valve models?
Model 4020 represents the Wafer type connection (4020L for lever, 4020G for gearbox), whereas Model 4325 represents the Lug type connection (4325L for lever, 4325G for gearbox).
How are the valves marked for identification on site?
Each unit features an identification data plate on the valve body displaying Tianjin top automation equipment Co.,Ltd, model, size, and PN rating.
Are large sizes like DN700 to DN1000 available in both PN10 and PN16?
Yes, dimensional specifications and flange drilling patterns are available for both PN10 and PN16 pressure standards from DN700 up to DN1000.
