Frequently Asked Questions (FAQ)
What are the body and disc material options for these butterfly valves?
The valves feature a blue epoxy-coated ductile iron body. The disc options include either stainless steel (CF8 or CF8M) or blue epoxy-coated ductile iron, sealed with a resilient EPDM seat.
What are the maximum temperature and pressure limits?
The valves operate safely under a maximum working pressure of 16.0 Bar and handle a maximum operating temperature of up to 85°C.
What actuator/operation types are available across sizes?
Sizes from DN40 to DN300 are available with lever and gearbox operations, while sizes from DN350 to DN600 and larger are strictly gear-operated.
What are the specific model numbers for Wafer and Lug styles?
Lever operated valves (DN40-DN300) are designated as Model 4020L for Wafer and 4325L for Lug. Gearbox operated valves (DN350-DN600) correspond to Model 4020G for Wafer and 4325G for Lug.
Where can identification markings and manufacturer data be verified on the valve?
The valve body features an official data plate displaying Tianjin top automation equipment Co.,Ltd, along with the specific model number, nominal size, and PN pressure rating.
Are large diameter valves available in both PN10 and PN16 pressure ratings?
Yes, large diameter butterfly valves from DN700 up to DN1000 are fully dimensioned and engineered for both PN10 and PN16 pressure ratings.
